                               PROSPECTUS SUMMARY

  This summary highlights selected information contained elsewhere in this
prospectus. You should read the entire prospectus carefully, including "Risk
Factors" and our consolidated financial statements, before making an investment
decision.

                                Sunrise Telecom

  We manufacture and market service verification equipment to pre-qualify,
verify and diagnose telecommunications and Internet networks. Our products
offer broad functionality, leading-edge technology and compact size to test the
variety of new digital subscriber line, or DSL, services, fiber optics, cable
TV networks and signaling networks. Digital subscriber line technology is a
high-speed, high capacity access service that operates over standard copper
telephone wires. We design our products to maximize technicians' effectiveness
in the field and to provide realistic network simulations for equipment
manufacturers to test their products. Our customers include incumbent local
exchange carriers, competitive local exchange carriers, and other service
providers, network infrastructure suppliers and installers throughout North
America, Latin America, Europe and the Asia/Pacific region. Affiliates of SBC
Communications Inc., which include Pacific Bell Telephone Company, Southwestern
Bell Telephone Company, Ameritech Corporation, Nevada Bell and Southern New
England Telephone, accounted for approximately 40.6% of our net sales in 1999.

  According to Ryan Hankin Kent, Inc., the number of DSL lines and cable TV
modems in homes and businesses in the United States and Canada will grow from
2.1 million in 1999 to 24.7 million in 2003. We believe that service
verification products are required for the efficient deployment and maintenance
of broadband networks and that the dramatic growth in broadband service, driven
by the Internet, will accelerate the need for our products. However, our growth
rate may not necessarily correspond with the growth rate of the installation of
DSL lines and cable TV modems. For the year ended December 31, 1999, our net
sales were approximately $61.5 million and our net income was approximately
$10.9 million.

  Our service verification products are used for a broad range of
telecommunications transmission and signaling technologies, including:

  .  DSL. Our new DSL products test the most popular types of DSL service,
     including asymmetric DSL, or ADSL, symmetric DSL, or SDSL, high bit-rate
     DSL, or HDSL, and integrated services digital network DSL, or IDSL. Our
     DSL products have accounted for virtually all of our net sales.

  .  Cable TV. We recently introduced a new service verification solution for
     cable network operators who are converting their analog cable networks
     into digital networks capable of providing Internet and voice services.

  .  Fiber Optics. We recently introduced three new products to verify fiber
     optic transmissions in the access network and to analyze services
     carried on fiber optics in the central office. Our fiber optic products
     allow service providers to verify fiber optic services based on North
     American and international transmission standards.

  .  Signaling. We recently introduced an Internet browser-based remote
     testing and surveillance solution for service providers to test and
     monitor various and changing signaling protocols.

  Our products offer the following key benefits:

  .  Design Flexibility. We design our products to be flexible and to evolve
     as customer needs change. For instance, a flexible design allows the
     customer to adapt their SunSet xDSL test set to new DSL services and
     applications as network standards evolve, thereby protecting the
     customer's investment in the test equipment.

                                       3
<PAGE>


  .  Customer Driven Features. Each of our products is highly tailored to our
     customers' needs. Our marketing engineers continually interact with our
     customers during the design process to ensure that our products are the
     best available solution for them.

  .  Handheld Design. Most of our DSL and fiber optic products weigh less
     than three pounds and offer handheld convenience. The compact,
     lightweight design of these products enable field technicians to access
     problems and verify line operation quickly.

  .  Rapid and Efficient DSL Deployment. Our products allow field and office
     technicians to test DSL lines rapidly and efficiently to ensure that
     they are properly connected to the central office and that they can
     support a specific type and speed of DSL service. In a single device,
     our products can be used to pre-qualify facilities for services,
     identify the source of problems and verify the proper operation of newly
     installed service before handing service over to customers.

  .  Improved Network Quality and Reliability. Field and office technicians
     use our products to diagnose and locate a variety of problems and
     degradations in broadband service. This allows service providers to
     identify and repair problems and to restore service efficiently. As a
     result, our products support our customers' need to provide high quality
     and reliable service.

  Our objective is to be a significant provider of service verification test
equipment for a broad range of applications within the global
telecommunications industry. The key elements of our strategy are to maintain
our position in DSL service verification equipment, to penetrate the growing
market for verification test equipment for fiber optics and cable TV, to expand
beyond field verification testing into remote testing, alarm and surveillance
and central office testing applications, to continue to expand internationally,
to pursue strategic acquisitions and joint ventures and to pursue follow-on
sales opportunities by continuing to develop and market hardware modules which
can be inserted into our service verification equipment.

  We were incorporated in California as Sunrise Telecom, Inc. in October 1991.
In July 2000, we reincorporated as a Delaware corporation and changed our name
to Sunrise Telecom Incorporated. Our principal executive offices are located at
22 Great Oaks Boulevard, San Jose, California 95119, and our telephone number
is (408) 363-8000. We maintain Web sites at www.sunrisetelecom.com,
www.hukk.com, www.ghepardo.com and www.protel-italy.com. Information contained
on our Web sites does not constitute part of this prospectus.

                                  RISK FACTORS

  You should carefully consider the risks described below before making an
investment decision.

                         Risks Relating to Our Business

Quarterly Fluctuations--Because our quarterly operating results have fluctuated
   significantly in the past and are likely to fluctuate significantly in the
   future, our stock price may decline and may be volatile.

  In the past, we have experienced significant fluctuations in our quarterly
results due to a number of factors beyond our control. In the future, we expect
that our quarterly operating results may fluctuate significantly and will be
difficult to predict given the nature of our business. Many factors could cause
our operating results to fluctuate from quarter to quarter in the future,
including the following:

  .  the size and timing of orders from our customers, in each case
     exacerbated by the lengthy and unpredictable buying patterns of our
     customers, and our ability to ship these orders on a timely basis;

  .  the degree to which our customers have allocated and spent their yearly
     budgets, which has, in some cases, resulted in higher net sales in our
     fourth quarter;

  .  the uneven pace of technology innovation, the development of products
     responding to these technology innovations by us and our competitors and
     customer acceptance of these products and innovations;

  .  the varied degree of price, product and technology competition, which
     has been buffeted by the rapid changes in the telecommunications
     industry and our customers' and competitors' responses to these changes;

  .  the relative percentages of our products sold domestically and
     internationally; and

  .  the mix of the products we sell and the varied margins associated with
     these products.

  The factors listed above may affect our business and stock price in several
ways, including the following:

  .  Given the high fixed costs relating to overhead, research and
     development, advertising and marketing, among others, if our net sales
     are below our expectations in any quarter, the negative effect may be
     magnified by our inability to adjust spending in a timely manner.

  .  As a result of the above, our stock price may decline and may be
     volatile, particularly if public market analysts and investors perceive
     these factors to exist, whether or not that perception is accurate.

  .  Finally, the above factors, taken together may make it more difficult
     for us to issue additional equity in the future or raise debt financing
     to fund future acquisitions and accelerate growth.

Customer Concentration--A limited number of customers account for a high
   percentage of our net sales, and any adverse factor affecting these
   customers or our relationship with these customers could cause our net sales
   to decrease.

  Our customer base is highly concentrated, and a relatively small number of
companies have accounted for a large percentage of our net sales. Net sales
from our top five customers in the United States represented approximately
16.4% of net sales in 1997, 15.9% in 1998 and 49.4% in 1999. Our largest
customers over this period have been affiliates of SBC Communications Inc.,
which include Pacific Bell Telephone Company, Southwestern Bell Telephone
Company, Ameritech Corporation, Nevada Bell and Southern New England Telephone
and which in total accounted for approximately 40.6% of net sales in

                                       7
<PAGE>

fiscal 1999. No customer is presently obligated to purchase a specific amount
of products or to provide us with binding forecasts of purchases for any
period. We expect that we will continue to depend upon SBC Communications'
affiliates and other major customers for a substantial portion of our net sales
in future periods. We cannot guarantee that our future net sales, including
those from SBC Communications' affiliates, will be comparable to our fiscal
1999 net sales. The loss of a major customer or the reduction, delay or
cancellation of orders from one or more of our significant customers could
cause our net sales and, therefore, profits to decline. In addition, many of
our customers are able to exert substantial negotiating leverage over us. As a
result, they may cause us to lower our prices and negotiate other forms and
provisions that may negatively affect our business and profits.

Dependence on DSL--Substantially all of our sales have been from our DSL
   products. If the market for DSL services does not continue to grow as we
   anticipate, our net sales could decline.

  In 1999, sales of our DSL products represented approximately 97.5% of our net
sales. Currently, our DSL products are primarily used by a limited number of
incumbent local exchange carriers, including the regional Bell operating
companies, and competitive local exchange carriers, who offer DSL services. A
competitive local exchange carrier is a company that, following the
Telecommunications Act of 1996, is authorized to compete in a local
communications services market. These parties, and other Internet service
providers and users, are continuously evaluating alternative high-speed data
access technologies, including cable modems, fiber optics, wireless technology
and satellite technologies, and may at any time adopt these competing
technologies. These competing technologies may ultimately prove to be superior
to DSL services and reduce or eliminate the demand for our DSL products.

  In addition, the availability and quality of DSL service may be impaired by
technical limitations and problems of the existing copper wire network on which
DSL service runs, such as:

  .  the distance of end users from the central office of the incumbent local
     exchange carrier, which is typically limited to between 12,000 and
     18,000 feet;

  .  the quality and degree of interference with the copper wire network;

  .  the configuration of the copper wire network, which may degrade or
     prevent DSL service;

  .  the ability of DSL networks and operational support systems of service
     providers to connect and manage a substantial number of online end users
     at high speeds, while achieving reliable and high quality service; and

  .  the vulnerability of the copper wire network to physical damage from
     natural disasters and other unanticipated telecommunications failures
     and problems.

Accordingly, our future success is substantially dependent upon whether DSL
technology gains widespread market acceptance by these companies, end users of
their services and other Internet service providers and users.

  To date, our customers have deployed DSL equipment, including our products,
in substantially larger volumes than their current subscriber count. The
inability of our current or future customers to acquire and retain subscribers
as planned, or to respond to competition for their services or reduced demand
for their services, could cause them to reduce or eliminate their DSL
deployment plans. If our customers are forced to reduce or eliminate their DSL
deployment plans, our sales to them will decline.

Use of Field Technicians--If service providers reduce their use of field
   technicians and successfully implement a self-service installation model,
   demand for our products could decrease.

  To ensure quality service, our major service provider customers, including
SBC Communications, typically send a technician who uses our product into the
field to verify service for installations. However, SBC Communications has
recently announced plans to encourage their customers to install their own DSL
service. U.S. West and Bell Atlantic already encourage customers to install DSL
themselves. By encouraging

                                       8
<PAGE>

customers to install DSL themselves, these phone companies intend to reduce
their expenses and expedite installation for their customers. To encourage
self-installation, these companies offer financial incentives. If SBC and other
service providers successfully implement these plans or choose to send
technicians into the field only after a problem has been reported, or if
alternative methods of verification become available, such as remote
verification, the need for field technicians and the need for our products
could decrease.

Sales Implementation Cycles--The length and unpredictability of the sales and
   implementation cycles for our products makes it difficult to forecast
   quarterly revenues.

  Sales of our products often entail an extended decision-making process on the
part of prospective customers. We frequently experience delays following
initial contact with a prospective customer and expend substantial funds and
management effort pursuing these sales. Our ability to forecast the timing and
amount of specific sales is therefore limited. As a result, the uneven buying
patterns of our customers may cause fluctuations in our quarterly operating
results, which could cause our stock price to decline. For more information
regarding the length and unpredictability of our sales and implementation
cycles, see "Business--Sales, Marketing and Customer Service."

  Other sources of delays that lead to long sales cycles, or even a sales loss,
include: potential customers' internal approval and contracting procedures,
procurement practices, and testing and acceptance processes. As a result, the
sales cycle for larger deployment of selected products typically ranges from
six to 24 months for new deployment of selected product sales, and up to six
months for occasional large selected product sales. The deferral or loss of one
or more significant sales could significantly affect operating results in a
particular quarter, especially if there are significant sales and marketing
expenses associated with the deferred or lost sales.

Product Enhancements--If we are unable to enhance our existing products and
   successfully manage the development of new products, our future success may
   be threatened.

  The market for our products is characterized by rapid technological advances,
changes in customer requirements and preferences, evolving industry and
customer-specific protocol standards and frequent new product enhancements and
introductions. Our existing products and our products currently under
development could be rendered obsolete by the introduction of products for
telecommunications networks involving competing technologies, by the evolution
of alternative technologies or new industry protocol standards and by rival
products introduced by our competitors. These market conditions are made more
complex and challenging by the high degree to which the telecommunications
industry is fragmented.

  We believe our future success will depend, in part, upon our ability, on a
timely and cost-effective basis, to continue to:

  .  anticipate and respond to varied and rapidly changing customer
     preferences and requirements, a process made more challenging by our
     customers' buying patterns;

  .  anticipate and develop new products and solutions for networks based on
     emerging technologies, such as the asynchronous transfer mode protocol
     that packs digital information into cells to be routed across a network,
     and Internet telephony, which comprises voice, video, image and data
     across the Internet, that are likely to be characterized by continuing
     technological developments, evolving industry standards and changing
     customer requirements;

  .  invest in research and development to enhance our existing products and
     to introduce new verification and diagnostic products for the
     telecommunications, Internet, cable network and other markets; and

  .  support our products by investing in effective advertising, marketing
     and customer support.

We cannot assure you that we will accomplish these objectives, and our failure
to do so could have a material adverse impact on our market share, business and
financial results.

                                       9
<PAGE>

Potential Product Liability--Our products are complex, and our failure to
   detect errors and defects may subject us to costly repairs, product returns
   under warranty and product liability litigation.

  Our products are complex and may contain undetected defects or errors when
first introduced or as enhancements are released. These errors may occur
despite our testing and may not be discovered until after a product has been
shipped and used by our customers. This risk is compounded by the fact that we
offer over 20 products, with multiple hardware and software modifications,
which makes it more difficult to ensure high standards of quality control in
our manufacturing process. The existence of these errors or defects could
result in costly repairs and/or returns of products under warranty and, more
generally, in delayed market acceptance of the product or damage to our
reputation and business.

  In addition, the terms of our customer agreements and purchase orders, which
provide us with protection against unwarranted claims of product defect and
error, may not protect us adequately from unwarranted claims against us, unfair
verdicts if a claim were to go to trial, settlement of these kinds of claims or
future regulation or laws regarding our products. Our defense against these
claims in the future, regardless of their merit, could result in substantial
expense to us, diversion of management time and attention, damage to our
business reputation and hurt our ability to retain existing customers or
attract new customers.

Managing Growth--We may have difficulties managing our expanding operations,
   which could reduce our chances of maintaining our profitability.

  We have recently experienced rapid growth in revenues and in our business
generally that has placed, and we expect will continue to place, a significant
strain on our management and operations. For example, our revenues have
increased from $28.5 million in 1998 to $61.5 million in 1999, our number of
employees has increased from 118 at December 31, 1998 to 228 at March 31, 2000,
and we have made two important acquisitions, that of Hukk Engineering and
Pro.Tel. As a result of our historical and expected growth, we face several
risks, including:

  .  the need to improve our operational, financial, management,
     informational and control systems;

  .  the need to hire, train and retain highly skilled personnel in a market
     where there are already severe shortages of these kinds of personnel, as
     we discuss below; and

  .  the possibility that our management's attention will be diverted from
     running our business to the needs of managing a public company.

We cannot assure you that we will be able to manage this growth profitably.

Competition--Competition could reduce our market share and decrease our net
   sales.

  The market for our products is fragmented and intensely competitive both in
and outside the United States, and is subject to rapidly evolving industry
standards and varied and changing customer preferences and requirements. Our
principal competitors are described in "Business--Competition." Many of these
competitors have longer operating histories, larger installed customer bases,
longer relationships with customers, wider name recognition and product
offerings and greater financial, technical, marketing, customer service and
other resources than we do. On May 23, 2000, Dynatech, Inc. and Wavetek Wandel
Goltermann, Inc announced the completion of the merger of TTC, a division of
Dynatech, and Wavetek, which could make the combined company a more formidable
competitor.

  We expect that, as our industry and market evolves, new competitors or
alliances among competitors with existing and new technologies could emerge and
acquire significant market share. We anticipate that competition in our market
will increase and we will face greater threats to our market share, price
pressure on our products and the likelihood that, over time, our profitability
may decrease. In addition, it is difficult

                                       10
<PAGE>

to assess accurately the market share of our products or of Sunrise overall
because of the high degree of fragmentation in the market for DSL service
verification equipment, in particular, and for high-speed data access
technology, in general. As a result, it may be difficult for us to forecast
accurately trends in the market, which of our products will be the most
competitive over the longer term and, thus, what is the best use of our human
and other form of capital. We cannot assure you that we will be able to compete
effectively. For discussion of the principal competitive factors in our market,
see "Business--Competition."

Need for New Personnel--If we cannot hire and train the R&D, manufacturing,
   sales, and marketing personnel we need to support our anticipated growth,
   our plans for continued expansion will be hampered.

  Our business requires engineers, technicians and other highly trained and
experienced personnel. In particular, since our products require a
sophisticated selling effort targeted at several key people within our
prospective customers' organizations, we have a special need for experienced
sales personnel as well as specialized engineers. In addition, the complexity
of our products and the difficulty of configuring and maintaining them require
highly trained customer service and support personnel. If we continue to grow,
we will need to hire a significant number of engineering, sales, marketing and
customer service and support personnel in the future, in and outside the United
States. Given that competition for such persons is intense, especially in the
San Francisco Bay Area, we may not be successful in attracting and retaining
these individuals. Our failure to hire, train and keep these kinds of employees
could impair our ability to grow profitably. In addition, if we do hire new
personnel, the addition of significant numbers of new personnel will require us
to incur significant start-up expenses, including procurement of office space
and equipment, initial training costs, and may result in low productivity rates
of these new personnel. These start-up expenses may adversely affect our future
operating results.

Reliance On Non-U.S. Workers--If U.S. immigration policies prevent us from
   hiring or retaining the workers we need, our growth may be limited.

  In the past we have filled a significant portion of our new personnel needs,
particularly for our engineers, with non-U.S. citizens holding temporary work
visas that allow these persons to work in the United States for a limited
period of time. We rely on these non-U.S. workers because of the shortage of
engineers, technicians and other highly skilled and experienced workers in the
telecommunications industry in the United States, in general, and in the San
Francisco Bay Area, in particular. Regulations of the Immigration and
Naturalization Service permit non-U.S. workers a limited number of extensions
for their visas and also set quotas regarding the number of non-U.S. workers
U.S. companies may hire. As a result, we face the risk that a portion of our
existing employees may not be able to continue to work for us, thereby
disrupting our operations, and that we may not be able to hire the number of
engineers, technicians and other highly skilled and experienced workers that we
need to grow our business. Furthermore, changes in these regulations could
exacerbate these risks.

Dependence on Key Employees--If one or more of our senior managers were to
   leave, we could experience difficulties in replacing them and our operating
   results could suffer.

  Our success depends to a significant extent upon the continued service and
performance of a relatively small number of key senior management, technical,
sales and marketing personnel. The loss of any of our three founders, Paul Ker-
Chin Chang, Paul A. Marshall and Robert C. Pfeiffer, in particular, would
likely harm our business. None of these individuals is bound by an employment
agreement with us, and we do not carry key man life insurance on them. In
addition, competition for senior level personnel with telecommunications
knowledge and experience is intense. If any of our senior managers were to
leave Sunrise, we would need to devote substantial resources and management
attention to replace them. As a result, management attention may be diverted
from managing our business and we may need to pay higher compensation to
replace these employees.

                                       11
<PAGE>

Risks of International Operations--Our plan to expand sales in international
   markets could lead to higher operating expenses and may subject us to
   unpredictable regulatory and political systems.

  Sales to customers located outside of the United States represented 46% of
our net sales in 1997, 42% in 1998 and 20% in 1999, and we expect international
revenues to continue to account for a significant percentage of net sales for
the foreseeable future. In addition, an important part of our strategy calls
for further expansion into international markets. As a result, we will face
various risks relating to our international operations, including:

  .  potentially higher operating expenses, resulting from the establishment
     of international offices, the hiring of additional personnel and the
     localization and marketing of products for particular countries'
     technologies;

  .  the need to establish relationships with government-owned or subsidized
     telecommunications providers as well as additional distributors;

  .  fluctuations in foreign currency exchange rates and the risks of using
     hedging strategies to minimize our exposure to these fluctuations, which
     have been heightened by our recent acquisition of Pro.Tel, whose
     revenues have been and are likely to continue to be in Italian lira; and

  .  potentially adverse tax consequences related to acquisitions and
     operations, including the ability to claim goodwill deductions and a
     foreign tax credit against U.S. federal income taxes, especially since
     Italy has a higher tax rate.

We cannot assure you that one or more of these factors will not materially and
adversely affect our ability to expand into international markets, our revenues
and profits.

  In addition, since the last six months of 1997, the Asia/Pacific region has
experienced instability in many of its economies and significant devaluations
in local currencies. Approximately 20% of our sales in 1998 and 9% of our sales
in 1999 were derived from customers located in this region. These instabilities
may continue or worsen, which could have a materially adverse effect on our
results of operations. If international revenues are not adequate to offset the
additional expense of expanding international operations, our future growth and
profitability could suffer.

Dependence on Sole and Single Source Suppliers--Because we depend on a limited
   number of suppliers and some sole and single source suppliers that are not
   contractually bound in the long-term, our future supply of product
   components is uncertain. This could lead to manufacturing difficulties.

  In our manufacturing process, we purchase many key products, such as
microprocessors, bus interface chips, optical components and oscillators, from
a single source or sole supplier and we license certain software from third
parties. We rely exclusively on third-party subcontractors to manufacture some
sub-assemblies, and we have retained, from time to time, third party design
services in the development of our products. We do not have long-term supply
agreements with these vendors. In general, we make advance purchases of some
products and components to ensure an adequate supply, particularly for products
that require lead times of up to six months to manufacture. In the past, we
have experienced supply problems as a result of financial or operational
difficulties of our suppliers, shortages, discontinuations resulting from
component obsolescence or other shortages or allocations of supplies. Our
reliance on these third parties involves a number of risks, including:

  .  the unavailability of critical products and components on a timely
     basis, on commercially reasonable terms or at all;

  .  if products or software licenses were to become unavailable, the need to
     qualify new or alternative products or develop or license new software
     for our use and/or to reconfigure our products and manufacturing
     process, each of which could be lengthy and expensive;

                                       12
<PAGE>

  .  the likelihood that, if these products are not available, we would
     suffer an interruption in the manufacture and shipment of our products
     until the products or alternatives become available;

  .  reduced control over product quality and cost, risks exacerbated by the
     need to respond, at times, to unanticipated changes and increases in
     customer orders; and

  .  the unavailability of, or interruption in, access to some process
     technologies.

In addition, the purchase of these components on a sole source basis subjects
us to risks of price increases and potential quality assurance problems. This
dependence magnifies the risk that we may not be able to ship our products on a
timely basis to satisfy customers' orders. We cannot assure you that one or
more of these factors will not cause delays or reductions in product shipments
or increases in product costs, which in turn could have a material adverse
effect on our business. See "Business--Manufacturing."

Acquisitions--We have acquired two companies and intend to pursue further
   acquisitions in the future. These activities involve numerous risks,
   including the use of cash, amortization of goodwill and the diversion of
   management attention.

  Recently, we acquired two companies, Hukk Engineering in July 1999, and
Pro.Tel in February 2000. As a result of these acquisitions, we face numerous
risks, including:

  .  integrating the existing management, sales force, technicians and other
     personnel into one existing culture and business;

  .  combining manufacturing, administrative and management information and
     other control systems into our corresponding systems;

  .  developing and implementing an integrated business strategy from what
     had been previously three independent companies; and

  .  developing compatible or complementary products and technologies from
     previously independent operations. For Hukk Engineering, this means
     addressing the convergence of telephony and cable products.

The risks stated above will be made more difficult because Hukk Engineering is
located in Norcross, Georgia and Pro.Tel is located in Modena, Italy and
Springfield, Virginia. In addition, if we make future acquisitions, these risks
will be exacerbated by the need to integrate additional operations at a time
when we may not have fully integrated Hukk Engineering and Pro.Tel.

  If we pursue further acquisitions, we will face similar risks as those above
and additional risks, including:

  .  the diversion of our management's attention and the expense of
     identifying and pursuing suitable acquisition candidates, whether or not
     consummated;

  .  negotiating and closing these transactions;

  .  the potential need to fund these acquisitions by dilutive issuances of
     equity securities and by incurring debt; and

  .  the potential negative effect on our financial statements from the
     increase in goodwill and other intangibles, the write-off of research
     and development costs and the high cost and expenses of completing
     acquisitions.

We cannot assure you that we will locate suitable acquisition candidates or
that, if we do, we will be able to acquire them and then integrate them
successfully and efficiently into our business.

                                       13
<PAGE>

Risks of the Telecommunications Industry--We face several risks regarding the
   telecommunications industry, including the possible effects of its rapid and
   unpredictable growth, the possible effects of consolidation among our
   principal customers and the risk that deregulation will slow.

  Since the passage of the Telecommunication Act of 1996, the
telecommunications industry has experienced rapid growth. This has and will
likely continue to lead to great innovations in technology, intense
competition, short product life cycles and, to some extent, regulatory
uncertainty in and outside the United States. The course of the development of
the telecommunications industry is, however, difficult to predict. As a result,
companies who operate in this industry have a difficult time forecasting future
trends and developments and the acceptance of competing technologies. One
possible effect of this uncertainty is that there may be, in the future, a
delay or a reduction in these companies' investment in their business and
purchase of related equipment, such as our products, and a reduction in their
and our access to capital. Moreover, in the short-term, deregulation may result
in a delay or a reduction in the procurement cycle because of the general
uncertainty involved with the transition period of businesses.

  The telecommunications industry has been experiencing consolidation among its
primary participants, such as incumbent local exchange carriers and competitive
local exchange carriers, several of whom are our primary customers. For
example, in recent years, SBC acquired Pacific Bell and Ameritech, both of
which were customers of ours. Continued consolidation may cause delay or cause
cancellation of orders for our products. In addition, the consolidation of our
customers will likely provide them with greater negotiating leverage with us
and may lead them to pressure us to lower the prices of our products.

  Because the market for our products has grown with the deregulation of
portions of the telecommunications industry, we face the risk that these trends
may slow or may be reversed. For example, in the United States, there is
litigation pending that challenges the validity of the Telecommunications Act
of 1996 and the local telephone competition rules adopted by the Federal
Communications Commission to implement that act. If deregulation in
international markets and in the United States were to slow or to take an
unanticipated course, the telecommunications industry might suffer the
following effects:

  .  greater consolidation of providers of high-speed access technologies,
     which may not favor the development of DSL technology and which might
     provide these companies with greater negotiating leverage regarding the
     prices and other terms of the DSL products and services they purchase;

  .  uncertainty regarding judicial and administrative proceedings, which may
     affect the pace at which investment and deregulation continue to occur;

  .  a general slowdown in economic activity relating to the
     telecommunications industry and a consequent multiplier effect on the
     general economy;

  .  reduced investment in the telecommunications industry in general and in
     DSL technology in particular due to increased uncertainty regarding the
     future of the industry and this technology; and

  .  delay in purchase orders of service verification equipment, such as our
     products, if they were to reduce their investment in new high-speed
     access technologies.

Intellectual Property Risks--Policing any unauthorized use of our intellectual
   property by third parties and defending any intellectual property
   infringement claims against us could be expensive and disrupt our business.

  Our intellectual property and proprietary technology is an important part of
our business, and we depend on the development and use of various forms of
intellectual property and proprietary technology. As a result, we are subject
to several related risks, including the risks of unauthorized use of our
intellectual property and the costs of protecting our intellectual property.

                                       14
<PAGE>

  Much of our intellectual property and proprietary technology is not protected
by patents. If unauthorized persons were to copy, obtain or otherwise
misappropriate our intellectual property or proprietary technology without our
approval, the value of our investment in research and development would
decline, our reputation and brand could be diminished and we would likely
suffer a decline in revenue. We believe these risks, which are present in any
business in which intellectual property and proprietary technology play an
important role, are exacerbated by the difficulty in finding unauthorized use
of intellectual property in our business, the increasing incidence of patent
infringement in our industry in general and the difficulty of enforcing
intellectual property rights in some foreign countries.

  In addition, litigation has in the past been, and may in the future be,
necessary to enforce our intellectual property rights. This kind of litigation
is time-consuming and expensive to prosecute or resolve, and results in
substantial diversion of management resources. We cannot assure you that we
will be successful in that litigation, that our intellectual property rights
will be held valid and enforceable in any litigation or that we will otherwise
be able to protect our intellectual property and proprietary technology. See
"Business--Intellectual Property and Proprietary Technology."

                        Risks Relating to this Offering

Concentration of Control--Our executive officers and directors will retain
   significant control over us after this offering, which will allow them to
   decide the outcome of matters submitted to stockholders for approval. This
   influence may not be beneficial to all stockholders.

  Upon completion of the offering, Mr. Chang, Mr. Marshall and Mr. Pfeiffer
will beneficially own 26.8%, 24.5% and 13.0% of our outstanding shares of
common stock (26.3%, 24.0% and 12.8%, if the underwriters' over-allotment
options are exercised in full). Consequently, these three individuals, acting
together, will be able to control the election of our directors and the
approval of significant corporate transactions that must be submitted to a vote
of stockholders. In addition, Mr. Chang, Mr. Marshall and Mr. Pfeiffer will
constitute three of the six members of the board of directors and will have
significant influence in directing the actions taken by the directors. The
interests of these persons may conflict with your interests as stockholders,
and the actions they take or approve may be contrary to those desired by other
stockholders. This concentration of ownership and control of the management and
affairs of our company may also have the effect of delaying or preventing a
change in control of our company that stockholders may consider desirable. See
"Management" and "Principal and Selling Stockholders."

Anti-takeover Provisions--Anti-takeover provisions in our charter documents
   could prevent or delay a change of control, and as a result, negatively
   impact our stockholders.

  Some provisions of our certificate of incorporation and bylaws may have the
effect of discouraging, delaying or preventing a change in control of our
company or unsolicited acquisition proposals that you, as a stockholder, may
consider favorable. These provisions provide for:

  .  authorizing the issuance of "blank check" preferred stock;

  .  a classified board of directors with staggered, three-year terms;

  .  prohibiting cumulative voting in the election of directors;

  .  requiring super-majority voting to effect certain amendments to our
     certificate of incorporation and by-laws;

  .  limiting the persons who may call special meetings of stockholders;

  .  prohibiting stockholder action by written consent; and

  .  establishing advance notice requirements for nominations for election to
     the board of directors or for proposing matters that can be acted upon
     at stockholders meetings.

Some provisions of Delaware law and our stock incentive plans may also have the
effect of discouraging, delaying or preventing a change in control of our
company or unsolicited acquisition proposals. These provisions also could limit
the price that some investors might be willing to pay in the future for shares
of our common stock. See "Management--Benefit Plans," "Description of Capital
Stock--Delaware Anti-Takeover Law and Charter and Bylaw Provisions" and
"Description of Capital Stock--Indemnification Provisions."

No Prior Public Market--There has been no prior public market for our common
   stock, and our stock price may be volatile, resulting in potential
   litigation.

  Prior to this offering, there has been no public market for our common stock.
The initial public offering price for the common stock has been determined by
negotiations between our company and the underwriters, and may not be
representative of the price that will prevail in the open market. See
"Underwriting" for a discussion of the factors considered in determining the
initial public offering price. In addition, the public markets have experienced
volatility that has particularly affected the market prices of securities of
many technology and telecommunications companies for reasons that have been
unrelated to their operating results. As a result, you may face the following
risks:

  .  the market price of our common stock may decline below the initial
     offering price;

  .  an active trading market for our common stock may not develop, which may
     result in your not being able to sell the shares you purchase at
     attractive prices or at all; and

  .  volatility and a lack of liquidity for our common stock may impede our
     ability to raise additional capital to expand our business.

  In addition, if our stock price is volatile, we could face securities class
action litigation. In the past, following periods of volatility in the market
price of their stock, many companies have been the subjects of securities class
action litigation. If we were sued in a securities class action, it could
result in substantial costs and a diversion of management's attention and
resources and could cause our stock prices to fall further.

Sale of Shares--The sale of a substantial number of shares of our common stock
   after this offering may adversely affect our stock price.

  Beginning 180 days after the date of this prospectus, approximately
45,080,153 shares of our common stock held by existing stockholders will become
available for resale under Rule 144 and Rule 701 of the Securities Act. The
market price of our common stock could decline as a result of sales of
substantial amounts of common stock in the public market upon the expiration of
lockup agreements between the existing stockholders and the underwriters or the
perception that substantial sales could occur. These sales might also make it
difficult for us to sell equity securities in the future at a time and at a
price that we deem appropriate. See "Shares Eligible for Future Sale."

                           FORWARD-LOOKING STATEMENTS

  This prospectus contains forward-looking statements, which may be deemed to
include, but are not limited to, our business strategy, timing of and plans for
the introduction of new products and enhancements, plans for hiring additional
personnel, timing of and plans for opening new offices and the adequacy of
anticipated sources of cash, including the proceeds from this offering, to fund
our operations. Words such as "believes," "anticipates," "plans," "expects,"
"intends" and similar expressions are intended to identify forward-looking
statements, but are not the exclusive means of identifying such statements.

                                USE OF PROCEEDS

  We will receive net proceeds of approximately $52.1 million from the sale of
shares of common stock by us in this offering at an initial public offering
price of $15.00 per share after deducting underwriting commissions and
discounts and estimated offering expenses. We will not receive any of the
proceeds from the sale of shares by the selling stockholders.

  The principal purpose of this offering is to increase our equity capital, to
create a public market for our common stock, to facilitate our future access to
public equity markets, to provide liquidity for certain of our existing
stockholders, to improve the effectiveness of our stock option plan in
attracting and retaining key employees and to provide increased visibility of
Sunrise in a marketplace where many of our competitors are publicly held
companies.

  We may use up to $5.0 million to repay amounts drawn to finance our short-
term liquidity needs after March 31, 2000 under our line of credit. Our line of
credit bears interest at 0.25% less than the bank's prime rate, which was 9.0%
at March 31, 2000, and expires in May 2001. We have not made other specific
allocations regarding the remaining net proceeds, and we expect to use the net
proceeds from this offering to expand our business generally, including to fund
the following:

  .  general corporate purposes, including sales and marketing, research and
     development and general and administrative expenses;

  .  working capital;

  .  up to approximately $15.0 million for the construction of our new
     facility in San Jose, California, which we are building to accommodate
     our need for an increase in manufacturing capacity and employees; and

  .  the acquisition of businesses, products and technologies which are
     complementary with or support our business, product offerings and
     strategy.

Pending any use, the net proceeds will be invested in short-term, interest-
bearing securities.

                                DIVIDEND POLICY

  We have declared and paid cash dividends on our common stock since 1994. In
the future, our board of directors will determine whether we will pay dividends
on our common stock. Our line of credit limits the payment of dividends on our
common stock.

                                 CAPITALIZATION

  The following table sets forth our capitalization at March 31, 2000:

  .  on an actual basis; and

     net proceeds from the sale of 3,817,428 shares of common stock offered
     by us in this offering at an initial public offering price of $15.00 per
     share, after deducting underwriting discounts and commissions and
     estimated offering expenses, and to give effect to the expiration on May
     22, 2000 of the put arrangement on the 500,001 shares of common stock
     issued as part of the Pro.Tel acquisition.

  The number of shares of common stock listed in the following table excludes
the following:

  .  approximately 8,893,905 shares of common stock reserved for issuance
     under our 1993 stock option plan, our 2000 stock plan and our 2000
     employee stock purchase plan, of which 2,796,198 shares were subject to

                                    DILUTION

  At March 31, 2000, our actual net tangible book value was approximately $17.4
million or $0.38 per share. Actual net tangible book value per share represents
the amount of total actual tangible assets less total actual liabilities,
divided by the shares of common stock outstanding at March 31, 2000. After
giving effect to the sale of the 3,817,428 shares of common stock we are
offering, after deducting the underwriting discounts and commissions and
estimated offering expenses, our adjusted net tangible book value at March 31,
2000 would have been $69.5 million, or $1.40 per share. This represents an
immediate increase in as adjusted net tangible book value of $1.02 per share to
existing stockholders and an immediate dilution of $13.60 per share to new
investors. The following table illustrates this per share dilution:

  The discussion and tables above assume no exercise of the following:

  .  approximately 8,893,905 shares of common stock reserved for issuance
     under our 1993 stock option plan, our 2000 stock plan and our 2000
     employee stock purchase plan, of which 2,796,198 shares were subject to
     outstanding options at March 31, 2000 issued at a weighted average
     exercise price of $3.99 per share.

  Sales by the selling stockholders in this offering will reduce the number of
shares of common stock held by existing stockholders to 49,595,829 or
approximately 91.9% (44,995,829 shares, or approximately 90.7%, if the
underwriters' over-allotment option is exercised in full) of the total number
of shares of common stock outstanding upon the closing of this offering and
will increase the number of shares held by new public investors to 4 million or
approximately 8.1% (4,600,000 shares, or approximately 9.3%, if the
underwriters' over-allotment option is exercised in full) of the total number
of shares of common stock outstanding after this offering. See "Principal and
Selling Stockholders."

  We have prepared the following unaudited pro forma consolidated condensed

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

  The following discussion should be read in conjunction with our consolidated
financial statements and the related notes appearing at the end of this
prospectus.

Overview

  We manufacture and market service verification equipment to pre-qualify,
verify and diagnose telecommunications and Internet networks. We design our
products to maximize technicians' effectiveness in the field and to provide
realistic network simulations for equipment manufacturers to test their
products. Our customers include incumbent local exchange carriers, competitive
local exchange carriers, and other service providers, network infrastructure
suppliers and installers throughout North America, Latin America, Europe and
the Asia/Pacific region.

 Sources of Net Sales

  We sell our products predominantly to large telecommunications service
providers. These prospective customers generally commit significant resources
to an evaluation of our and our competitors' products and require each vendor
to expend substantial time, effort and money educating the prospective customer
about the value of the proposed solutions. Delays associated with potential
customers' internal approval and contracting procedures, procurement practices,
testing and acceptance processes are common and may cause potential sales to be
delayed or foregone. As a result of these and related factors, the sales cycle
of new products for large customers typically ranges from six to 24 months.
Substantially all of our sales are made on the basis of purchase orders rather
than long-term agreements or requirements contracts. As a result, we commit
resources to the development and production of products without having received
advance or long-term purchase commitments from customers.

  To date, a significant portion of our net sales has resulted from a small
number of relatively large orders from a limited number of customers. In 1999,
we sold approximately $25.0 million of our products to affiliates of SBC
Communications, which represented approximately 40.6% of our net sales. We
anticipate that our operating results for any given period will continue to be
dependent to a significant extent on large purchase orders, which can be
delayed or cancelled by our customers without penalty. In addition, we
anticipate that our operating results for a given period will continue to be
dependent on a small number of customers.

  Currently, competition in the telecommunications equipment market is intense
and is characterized by declining prices due to increased competition, new
products and increasing unit volumes. Due to competition and potential pricing
pressures from large customers in the future, we expect that the average
selling price and gross margins for our products will decline over time. If we
fail to reduce our production costs accordingly, our gross margins will
correspondingly decline. See "Risk Factors--Competition and --Risks of the
Telecommunications Industry."

  During the last three years, a substantial portion of our net sales were
derived from customers located outside of the United States, and we believe
that continued growth will require expansion of our sales in international
markets. Currently, we maintain a procurement support and manufacturing
facility in Taipei, Taiwan, a representative liaison office in Beijing, China,
a foreign sales corporation in Barbados and manufacturing, research and
development and sales facilities in Modena, Italy and expect to establish
additional international sales and other offices in the future. Prior to our
acquisition of Pro.Tel, international sales have been denominated solely in
U.S. dollars and, accordingly, we have not been exposed to fluctuations in non-
U.S. currency exchange rates related to these sales activities. We have been
exposed, however, to fluctuations in non-U.S. currency exchange rates related
to our procurement activities in Taiwan. In the future, we expect that a
portion of international sales may be denominated in currencies

                                       24
<PAGE>

other than U.S. dollars, thereby exposing us to gains and losses on non-U.S.
currency transactions. We may choose to limit such exposure by entering into
various hedging strategies. See Note 14 of notes to consolidated financial
statements of Sunrise and "Risk Factors--Risks Relating to Our Business--Risks
of International Operations."

  We recognize product sales upon shipment to customers. We offer a three-year
warranty covering parts and labor on our DSL and fiber optic products sold in
the United States and a one-year warranty covering parts and labor for those
products sold overseas with a two-year extended warranty option at time of
sale. Our cable TV and signaling products are covered by a one-year warranty.
Sales of extended warranties are deferred and recognized over the extended
warranty term, which is generally two years. We charge estimated warranty costs
to cost of sales when the related sales are recognized. We recognize revenue
for out-of-warranty repair when we ship the repaired product.

 Cost of Sales

  Our cost of sales consist primarily of:

  .  direct material costs of product components, manuals, product
     documentation and product accessories sold;

  .  production wages, taxes and benefits;

  .  production allocated occupancy costs;

  .  warranty costs;

  .  the costs of board level assembly by third party contract manufacturers;
     and

  .  scrapped material used in the production process.

  Our industry is characterized by limited supply chains and long lead times
for materials and components we use in the manufacture of our products. If we
underestimate our requirements, we may have inadequate inventory, resulting in
additional costs to our products to expedite delivery of certain long lead time
components. An increase in the cost of components could result in lower
margins.

  Additionally, these long lead times have in the past, and may in the future,
cause us to attempt to mitigate these lead times by purchasing larger
quantities of some parts, increasing our investment in inventory and the risk
of the parts' obsolescence. Any subsequent write-off of inventory could also
result in lower margins. See "Risk Factors--Risks Relating to Our Business--
Dependence on Sole and Single Source Suppliers" and "Business--Manufacturing."

  We recognize direct cost of sales as we ship product. We expense scrapped
materials, wages, taxes, benefits and allocated occupancy costs as incurred.

 Operating Costs

  We classify our operating expenses into three general operational categories:
sales and marketing, research and development and general and administrative.
Our operating expenses also include stock-based compensation and amortization
of goodwill and other intangible assets. We classify all charges to the sales
and marketing, research and development and general and administrative expense
categories based on the nature of the expenditures. Although each of these
three categories includes expenses that are unique to the category type, there
are commonly recurring expenditures that are typically included in these
categories, such as salaries, amortization of stock-based compensation,
employee benefits, travel and entertainment costs, allocated communication,
rent and facilities costs and third party professional service fees. The sales
and marketing category of operating expenses also includes expenditures
specific to the sales and marketing group, such as those relating to
commissions, public relations and advertising, trade shows and marketing
materials.

  We allocate the total cost of overhead and facilities to each of the
functional areas that use overhead and facilities based upon the facilities
square footage used by each of these areas. These allocated charges

                                       25
<PAGE>

include facility rent and utilities for the corporate office, communications
charges and depreciation expense for office furniture and equipment.

  In 1999, we recorded amortization of deferred compensation expense of
$205,000 related to the grant of options to purchase our common stock at
exercise prices subsequently deemed to be below fair market value. Total
compensation expense related to options granted in 1999 will be amortized on a
straight-line basis to the departments in which the employees received these
below market option grants over the respective four-year vesting periods of the
options. In 1999, we allocated amortization of deferred compensation expense of
$17,000 to cost of sales, $111,000 to research and development expense, $58,000
to sales and marketing expense and $18,000 to general and administrative
expense. At December 31, 1999, $2,065,000 of deferred compensation expense
remained to be amortized at a rate not exceeding $142,000 per quarter.

 Acquisitions

  Recently, we purchased two companies, Hukk Engineering and Pro.Tel. In July
1999, we acquired Hukk Engineering, a manufacturer of digital cable testing
equipment. We accounted for the Hukk Engineering acquisition as a purchase and
recorded goodwill and other intangibles of approximately $2.5 million to be
amortized on a straight-line basis over the next five years. In February 2000,
we acquired Pro.Tel, an Italian manufacturer of distributed network signaling
analysis equipment, and its U.S. affiliate and the assets of an unrelated U.S.
distributor. We accounted for the Pro.Tel acquisition as a purchase and
recorded goodwill and other intangibles of approximately $9.4 million to be
amortized on a straight-line basis over the next five years. In addition, we
expect to record stock-based compensation for stock options granted to
employees of Pro.Tel subsequent to December 31, 1999 in the amount of $6.5
million to be amortized on a straight-line basis over their four year vesting
period. We believe that acquisitions and joint ventures may be an important
part of our growth and competitive strategy. See Note 11 of notes to
consolidated financial statements of Sunrise and "Risk Factors--Risks Relating
to Our Business--Acquisitions."

Comparison of Quarters Ended March 31, 1999 and 2000

  Net Sales. Net sales increased approximately 145% from $8.1 million in the
first quarter of 1999 to $19.8 million in the same period in 2000. Sales of our
xDSL products accounted for approximately $9.6 million of the net sales
increase, our new fiber optics products accounted for approximately $1.3
million of the net sales increase, and our new signaling products accounted for
approximately $552,000 of the net sales increase. We expect that sales growth
in the near future will be primarily from our xDSL, fiber optics and signaling
products.

  Sales to customers in North America, Europe, Asia and Latin America were $5.6
million, $948,000, $1.3 million and $246,000 in the first quarter of 1999,
respectively, and $15.8 million, $1.9 million, $1.6 million and $547,000 in the
first quarter of 2000, respectively. The strong increase in North American
sales is primarily due to the increase in sales to affiliates of SBC
Communications. Sales to SBC Communications affiliates increased from $1.3
million or 16.5% of total net sales in the first quarter of 1999 to $9.0
million or 45.5% of total net sales in the first quarter of 2000, primarily due
to purchases of our xDSL products.

  Cost of Sales. Cost of sales consists primarily of direct material, warranty
and personnel costs related to the manufacturing of our products and allocated
overhead. Cost of sales increased approximately 145% from $2.3 million in the
first quarter of 1999 to $5.6 million in the same period in 2000. The increase
in absolute dollars is primarily due to the increase in net sales. Cost of
sales represented approximately 28.2% of net sales in both the first quarter of
1999 and the first quarter of 2000.

  Research and Development. Research and development expenses consist primarily
of the costs of payroll and benefits for engineers, equipment and consulting
services. Research and development expenses increased approximately 97% from
$1.7 million in the first quarter of 1999 to $3.4 million in the same period in
2000. The increase in absolute dollars was primarily due to costs associated
with increased staffing dedicated to research and development activities. These
research and development expenses represented approximately 21.1% of net sales
during the first quarter of 1999 and approximately 16.9% in the same period in
2000. The decrease as a percentage of net sales in 2000 was primarily
attributable to increased product sales relative to research and development
expenditures. We expect that research and development expenses will increase in
absolute dollars for the foreseeable future as we intend to continue to invest
in product development.

  Sales and Marketing. Sales and marketing expenses consist primarily of
manufacturers' representatives and direct sales commissions, personnel, travel
and facilities expenses related to sales and marketing, and trade show and
advertising expenses. Sales and marketing expenses increased approximately 138%
from $2.1 million in the first quarter of 1999 to $5.1 million in the same
period in 2000. The increase in absolute dollars in 2000 was primarily related
to increased staffing to support expanded product offerings, increased
marketing and promotional activities and an increase in commissions paid to the
independent manufacturers' representatives. These sales and marketing expenses
represented approximately 26.3% of net sales in the first quarter of 1999 and
approximately 25.7% in the same period in 2000. The slight decrease as a
percentage of net sales during the first quarter of 2000 was primarily due to
our ability to leverage our base of resources to support a larger organization
which led to lower advertising and promotion, occupancy, and salary and related
expenses as a percentage of sales. We expect that sales and marketing expenses
will increase in absolute dollars for the foreseeable future as we intend to
continue to invest in our sales and marketing capabilities.

  General and Administrative. General and administrative expenses consist
primarily of personnel, facilities and other costs of our finance and
administrative departments, amortization of goodwill and other intangibles as
well as legal and accounting expenses. General and administrative expenses
increased approximately 175% from $522,000 in the first quarter of 1999 to $1.4
million in the same period in 2000.

                                       27
<PAGE>

These general and administrative expenses represented approximately 6.5% of net
sales in the first quarter of 1999 and approximately 7.3% in the same period in
2000. The increase in both absolute dollars and as a percentage of sales was
primarily related to increased staffing and related costs associated with the
growth of our business, amortization of goodwill and other intangible assets
related to recent business acquisitions and deferred compensation amortization.
We anticipate that general and administrative expenses will continue to
increase in absolute dollars for the foreseeable future as we accommodate our
growth, add related infrastructure and incur expenses related to being a public
company.

  Other Income, Net. Other income, net represents primarily interest earned on
cash balances. Other income, net increased from $71,000 in the first quarter of
1999 to $138,000 in the same period in 2000. The increase resulted from
increased interest earned on higher average balances of cash and cash
equivalents held during the quarter, partially offset by interest expense
incurred on a note payable related to the Hukk acquisition and from borrowings
under our line of credit.

  Income Taxes. Income taxes consist of federal, state and international income
taxes. We recorded income tax expense of $476,000 in the first quarter of 1999
and $1.7 million in the same period in 2000. Our effective income tax rates
were 31.3% in the first quarter of 1999 and 38.0% for the same period in 2000.
The effective income tax rate was higher in 2000 than in 1999 primarily due to
higher levels of income as well as an increased concentration of sales in local
jurisdictions with higher tax rates.

Comparison of Years Ended December 31, 1998 and 1999

  Net Sales. Net sales increased approximately 115.4% from $28.5 million in
1998 to $61.5 million in 1999. Sales of our xDSL products accounted for
approximately $30.0 million of the $33.0 million increase in net sales in 1999.
Sales to affiliates of SBC Communications represented approximately $22.8
million of the increase in 1999. We also introduced two new products in the
second half of 1999, the SunSet OCx and SS500, to address the fiber optic
transmissions testing market.

  Cost of Sales. Cost of sales increased approximately 94.2% from $7.6 million
in 1998 to $14.7 million in 1999. Cost of sales represented approximately 26.6%
of net sales in 1998 and approximately 24.0% in 1999. The decrease as a
percentage of net sales during 1999 resulted primarily from an increase in
domestic sales, which have higher gross margins than international sales as a
percentage of net sales and lower manufacturing costs due to volume discounts.

  Research and Development. Research and development expenses increased
approximately 72.4% from $6.2 million in 1998 to $10.7 million in 1999. The
increase in absolute dollars was primarily due to costs associated with
increased staffing dedicated to research and development activities. These
research and development expenses represented approximately 21.7% of net sales
during 1998 and approximately 17.4% in 1999. The decrease as a percentage of
net sales in 1999 was primarily attributable to increased product sales
relative to research and development expenditures.

  Sales and Marketing. Sales and marketing expenses increased approximately
96.0% from $7.8 million in 1998 to $15.2 million in 1999. The increase in
absolute dollars in 1999 was primarily related to increased staffing to support
expanded product offerings, increased marketing and promotional activities and
an increase in commissions paid to the independent manufacturers'
representatives. These sales and marketing expenses represented approximately
27.2% of net sales during 1998 and approximately 24.7% in 1999. The decrease as
a percentage of net sales during 1999 was primarily due to relatively higher
growth in sales in North America as a percentage of net sales.

                                       28
<PAGE>

  General and Administrative. General and administrative expenses increased
approximately 74.4% from $2.2 million in 1998 to $3.9 million in 1999. The
increase in absolute dollars was primarily related to increased staffing and
related costs associated with the growth of our business and professional and
legal fees associated with our successful patent lawsuit against Electrodata,
Inc. These general and administrative expenses represented approximately 7.9%
of net sales during 1998 and approximately 6.4% in 1999. The slight decrease as
a percentage of net sales during 1999 was primarily due to relatively higher
growth in net sales and our ability to leverage our base of resources to
support a larger organization.

  Other Income, Net. Other income, net increased from $224,000 in 1998 to
$327,000 in 1999. The increase in 1999 resulted from increased interest earned
on higher balances of cash and cash equivalents resulting from increased cash
flow from operations, partially offset by interest expense attributable to
notes payable.

  Income Taxes. We recorded income tax expense of $1.6 million in 1998 and $6.3
million in 1999. Our effective income tax rates were 32.0% in 1998 and 36.5% in
1999. The effective income tax rate was higher in 1999 than in 1998 primarily
due to higher levels of income as well as an increased concentration of sales
in local jurisdictions with higher tax rates.

Comparison of Years Ended December 31, 1997 and 1998

  Net Sales. Net sales decreased 1.8% from $29.1 million in 1997 to $28.5
million in 1998. The decrease in sales from 1997 to 1998 was primarily due to
the consolidation of two of our large customers, which resulted in delays in
orders for certain of our products as they integrated their purchasing
practices, a downturn in global economies, especially in Asia, deregulation in
Europe and privatization in Latin America.

  Cost of Sales. Cost of sales decreased approximately 0.8% from $7.7 million
in 1997 to $7.6 million in 1998. Cost of sales represented approximately 26.3%
of net sales in 1997 and 26.6% in 1998. The decrease in absolute dollars and
the slight increase as a percentage of net sales during 1998 resulted primarily
from the change in product mix and lower volume of new products sold in 1998
compared to 1997. Overall decreases in material costs were assisted by the
organization of Taiwan Sunrise Telecom Company Limited in 1998 to manage local
procurement activities in Taiwan. The material cost reductions were partially
offset by lower prices on our products in Asia and other countries during 1998
as well as start-up manufacturing, materials and integration expenses
associated with the initial release of SunLite E1, SunLite BRI, SunSet E8,
SunSet PDH, SunSet E20 and the SunSet xDSL. Quality standards and procedures
were also increased in 1998 as a result of ISO 9001 certification, which we
received in September 1998. The increased effort to maintain ISO 9001
certification, documentation and procedures increased additional expense to the
overall cost of goods sold.

  Research and Development. Research and development expenses increased
approximately 5.3% from $5.9 million in 1997 to $6.2 million in 1998. The
increase in both absolute dollars and as a percentage of net sales was
primarily due to costs associated with increased staffing dedicated to research
and development activities. These expenses represented approximately 20.3% of
net sales in 1997 and approximately 21.7% in 1998.

  Sales and Marketing. Sales and marketing expenses increased approximately
1.6% from $7.6 million in 1997 to $7.8 million in 1998. The increase in
absolute dollars in 1998 was primarily related to increased staffing as we
expanded product offerings and increased marketing and promotional activities.
These expenses represented approximately 26.3% of net sales during 1997 and
approximately 27.2% in 1998. The increase as a percentage of net sales during
1998 was primarily due to advertising and promotional expenses for new products
as well as an increase in travel expenses for expanded sales activities.

                                       29
<PAGE>

  General and Administrative. General and administrative expenses increased
approximately 37.4% from $1.6 million in 1997 to $2.2 million in 1998. The
increase in absolute dollars was primarily related to increased staffing and
related costs associated with the growth of our business. These expenses
represented approximately 5.6% of net sales during 1997 and approximately 7.9%
in 1998. The increase as a percentage of net sales during 1998 was primarily
due to increased staffing and related costs incurred in anticipation of future
growth as well as an increase in legal and professional fees associated with
our successful patent lawsuit against Electrodata, Inc.

  Other Income, Net. Other income, net increased from $112,000 in 1997 to
$224,000 in 1998. The increase in 1998 resulted from increased interest earned
on higher balances of cash and cash equivalents resulting from increased cash
flow from operations, partially offset by interest expense attributable to
notes payable.

  Income Taxes. We recorded income tax expense of $1.9 million in 1997 and $1.6
million in 1998. Our effective income tax rates were 30% in 1997 and 32% in
1998. The effective income tax rate was higher in 1998 than in 1997 primarily
due to reduced foreign sales corporation export benefits due to a reduction in
international sales as a percentage of net sales and research and development
tax credit benefits.

</TABLE>

  Our operating results have fluctuated from quarter to quarter due to a
variety of reasons. We note below some of the larger changes in various line
items in the table above.

  Net Sales. Net sales increased significantly during the quarter ended June
30, 1999 as compared to the first and third quarters of 1999. This was
primarily due to an increase in shipments of our SunSet xDSL product to Pacific
Bell, an affiliate of SBC Communications, as Pacific Bell began to accelerate
the installation of their ADSL service. Shipments in the third quarter of 1999
remained relatively level and then increased once again in the fourth quarter
of 1999 as Pacific Bell's year end orders increased.

  Gross Profit. Gross profit increased to 77.7% of net sales during the quarter
ended December 31, 1998 and increased again to 77.8% of net sales during the
quarter ended December 31, 1999, primarily due to an increase in domestic sales
as a percentage of net sales and the mix of product shipped during the quarter,
each of which led to higher gross profit. Gross profit decreased to 71.8% of
net sales during the quarter ended March 31, 2000, primarily due to a change in
the mix of product shipped during the quarter, which led to lower gross profit.

                                       31
<PAGE>

  Research and Development. During the quarters ended September 30, 1998 and
September 30, 1999, research and development expenses decreased in absolute
dollars due to the reduction in bonus accruals during the quarter,
corresponding with net sales declines during the third quarters of 1998 and
1999.

  Sales and Marketing. Sales and marketing expenses increased in absolute
dollars during the second and fourth quarters ended June 30, 1999 and December
31, 1999 due to increased spending in advertising and promotion of new products
during the quarters. Additional fluctuation in sales and marketing expense can
occur due to the geographical location of sales because we incur commission
expense on domestic sales whereas we incur a reduced sales price net of
distributor mark up on international sales.

  General and Administrative. General and administrative expenses generally
increased in absolute dollars during the nine quarters ended March 31, 2000
primarily due to increases in personnel and related costs required to support
our growth. The increase in general and administrative expense during the
quarters ended December 31, 1998 and June 30, 1999 through September 30, 1999
was related primarily to legal and professional expenses relating to our
successful patent litigation against Electrodata. During the quarters ended
December 31, 1999 and March 31, 2000, general and administrative expenses
increased due to a full quarter of amortization associated with the Hukk
Engineering acquisition and due to amortization expenses associated with the
Pro.Tel acquisition, respectively.

  We believe that quarterly revenues and operating results are likely to vary
significantly in the future and that quarter-to-quarter comparisons of our
results of operations are not necessarily meaningful and should not be relied
upon as indications of future performance. We cannot assure you that our net
sales will increase or be sustained or that we will be profitable in any future
period. Further, it is likely that there will be quarter to quarter
fluctuations in our operating results some of which may be below the
expectations of public market analysts and investors. For a discussion of the
factors that could affect our quarterly operating results and the possible
effects of these changes, see "Risk Factors--Risks Relating to Our Business--
Quarterly Fluctuations" and "Selected Consolidated Financial Data."

Backlog

  Our backlog of customer orders at December 31, 1999 was approximately $11.0
million. Variations in the size and delivery schedules of purchase orders that
we receive, as well as changes in customers' delivery requirements may result
in substantial fluctuations in the amount of backlog orders for our products
from quarter to quarter. Accordingly, we believe that our backlog cannot be
considered a meaningful indicator of our future financial results.

Seasonality

  We believe that our sales are seasonal in nature with the largest portion of
quarterly sales tied to the buying patterns of our customers which usually
increase during the last calendar quarter of the year as customers spend the
unused portion of their yearly budget. As a result, our first quarter sales
tend to decrease from the prior quarter.

Liquidity and Capital Resources

  Historically, we have financed our operations and satisfied our capital
expenditure requirements primarily through cash flow from operations. As of
December 31, 1999 and March 31, 2000, we had working capital of $16.0 million
and $14.0 million, respectively, and cash and cash equivalents of $8.6 million
and $1.8 million, respectively.

  Cash provided by operating activities was $2.4 million in 1997, $4.5 million
in 1998 and $10.1 million in 1999. Cash used in operating activities was $1.1
million for the three months ended March 31, 2000. Operating cash flows
decreased during the first quarter of 2000, primarily as a result of increases
in accounts receivable from our largest customer and increases in inventory
required to meet our expected future sales targets. Operating cash flows in
1999 increased primarily due to increased levels of income from operations,
partially offset by increases in accounts receivable due to increased sales
late in the period and increases in inventory.

                                       32

  Cash used in investing activities was $227,000 in 1997, $1.7 million in 1998,
$6.2 million in 1999 and $5.8 million for the three months ended March 31,
2000. For the quarter ended March 31, 2000, cash used in investing activities
included $4.1 million for the acquisition of Pro.Tel in February 2000 and
$1.7 million for capital expenditures. Cash used for capital expenditures
increased in the first quarter of 2000 primarily as a result of $400,000 used
for the purchase of the assets of Pro.Tel USA, $500,000 used to purchase
research and development equipment and $300,000 used to meet our demonstration
equipment requirements for the introduction of new products and an increase in
the number of our distribution channels. Our use of cash in investing
activities in 1999 was primarily related to a $2.7 million cash deposit for the
purchase of land for and construction of our new facility, a $782,000 payment
relating to the Hukk Engineering acquisition and $2.7 million of purchases of
property and equipment. We believe that capital expenditures in 2000 will
include approximately $15.0 million relating to the construction of our new
facility in San Jose, California, which we are building to accommodate our need
for an increase in manufacturing capacity and employees, and approximately $5.0
million for equipment, furniture and fixtures relating to the new facility. In
addition, due to anticipated growth in our operations and the increased
capacity afforded by our new facility, we believe that capital expenditures for
the acquisition of property and equipment relating to our ongoing business
activities will increase to a total of approximately $5.0 million in 2000.

  Cash used in financing activities was $396,000 in 1997, $263,000 in 1998 and
$311,000 in 1999. For the quarter ended March 31, 2000, cash provided by
financing activities included $370,000 received from the exercise of stock
options, partially offset by $288,000 for repayments of notes payable. Our use
of cash in financing activities in 1999 was primarily related to the repurchase
of $202,000 of our common stock and cash dividends of $223,000, offset by
proceeds from the exercise of stock options.

  Currently, we have a line of credit from Bank of America, N.A. for up to $9.0
million in borrowings at the bank's prime rate less 0.25% and expires on May 1,
2001. If this offering is not completed by August 2001, the borrowing limit
will be reduced to $6.0 million. At December 31, 1999 and March 31, 2000, there
were no balances outstanding under the line of credit. Borrowings under the
line of credit are secured by our inventory and accounts receivable. The
agreement governing the line of credit contains covenants, which we were in
compliance with at December 31, 1999 and March 31, 2000, that, among other
things:

  .  requires us to maintain various financial covenants, including
     profitability and current ratios;

  .  limits capital expenditures;

  .  restricts the payment of dividends on our common stock, including that
     offered by this prospectus, to dividends payable in common stock and to
     $750,000 payable in any one fiscal year or $1.0 million payable in any
     one fiscal year after this offering; and

  .  restricts our ability to redeem our common stock beyond 20% of our net
     income for the prior fiscal year.

  We believe that the net proceeds received by us from this offering, together
with current cash balances, cash flows from operations and available borrowings
under our line of credit will be sufficient to meet our anticipated cash needs
for working capital, capital expenditures and other activities for at least the
next 12 months. After that, if current sources are not sufficient to meet our
needs, we may seek additional equity or debt financing. In addition, any
material acquisition of complementary businesses, products or technologies or
material joint venture could require us to obtain additional equity or debt
financing. We cannot assure you that such additional financing would be
available on acceptable terms, if at all.

Qualitative and Quantitative Disclosure about Market Risk

  We sell our products in North America, Asia, Latin America and Europe. As a
result, our financial results could be affected by factors such as changes in
foreign currency exchange rates. As all sales are currently made in U.S.
dollars, a strengthening of the dollar could make our services less competitive
in foreign markets. Prior to the acquisition of Pro.Tel in February 2000, we
had not used derivative instruments to hedge our foreign exchange risks. Our
interest income is sensitive to changes in the general level of U.S. interest
rates, particularly since the majority of our investments are in money market
accounts. Due to the nature of our investments, we anticipate no material
market risk exposure.

Recent Accounting Pronouncements

  In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards, or SFAS, No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 established methods of
accounting for derivative financial instruments and hedging activities related
to those instruments as well as other hedging activities. Currently, we do not
hold any derivative instrument, so we expect that the adoption of SFAS No. 133
will not have a material impact on our financial position, results of
operations or cash flows. We will be required to implement SFAS No. 133 during
the year ending December 31, 2001.

Industry Background

 Demand for High-Speed Data Access

  The telecommunications industry is undergoing fundamental change and growth
worldwide. Following the Telecommunications Act of 1996, competitive local
exchange carriers in the United States have been allowed to compete with
incumbent local exchange carriers, including the regional Bell operating
companies, for local carrier services. The regulatory developments in the
telecommunications industry have coincided with a surge in demand for high-
speed Internet access and data transmission service. According to Ryan Hankin
Kent, Inc., data traffic in the United States and Canada has surpassed the
amount of voice traffic carried on the existing telephone network. At the end
of 1999, data traffic had reached 350,000 terabytes per month, approximately
seven times the level of voice traffic. Further, the research indicates that
streaming media or other large, multi-media intensive files account for ten
percent of all Internet traffic, while voice and fax over Internet protocol
represents two to three percent of all traffic. Consumers are seeking higher-
speed access to bandwidth intensive content and services, such as highly
graphical Web sites, audio, video and software downloads. As an increasing
number of Internet users access more and different content, the ability to
connect to and receive data from the Internet at high speeds has become and
will continue to be more important. Businesses have even greater requirements
for high-speed access to implement e-commerce strategies, to access the
Internet for a variety of purposes and to provide employees with effective
telecommuting capabilities. Outside the United States, there is evidence to
suggest that deregulation and the availability of broadband service will
continue and will follow the general trends in the United States.

  Service providers are responding to the increased demand with the deployment
of reliable high-speed, digital networks. One primary investment area is the
redesign of the access network to support broadband access to end users. This
portion of the network between the customer's premise and the service
provider's central office is also known as the "last-mile." The last mile
typically consists of copper wires that operate at

                                       35
<PAGE>

substantially lower transmission speeds than those offered in the long-haul
segment of a network or by some available broadband alternatives. These copper
wires were originally intended to carry only analog circuit-switched, low-speed
voice signals and, as a result, have become a bottleneck that limits high-speed
data transmission. Several access technologies are being deployed to support
higher-speed Internet access in the networks, including digital subscriber
lines, digital cable TV, fiber optics and broadband wireless. In addition, the
signaling portion of the network is essential to the integration of new
broadband services into the existing telecommunications network. We summarize
some of these technologies below.

  Digital Subscriber Line Technology. Digital subscriber line technology,
commonly known as DSL, today transmits data up to 50 times faster than a
conventional dial-up modem using the existing copper telephone wires. Various
implementations of DSL are being developed and deployed, including asymmetric
DSL, known as ADSL, symmetric DSL, know as SDSL, high bit-rate DSL, know as
HDSL, and integrated services digital network DSL, known as IDSL. Service
providers deploying DSL technology include incumbent local exchange carriers,
such as SBC Communications, Inc. and Bell Atlantic Corporation, as well as
competitive local exchange carriers, such as Rhythms NetConnections Inc., Covad
Communications Group, Inc. and Northpoint Communications Group, Inc.

  Cable TV Networks. Cable TV operators use two-way cable, cable modems
installed in the home, cable modem termination systems installed at major cable
concentration points and network headend equipment designed to interface their
cable TV networks to video feeds and other networks. Several cable companies
are currently offering broadband access services across two-way cable,
including Excite@Home, Road Runner, Softnet Systems, Inc., High Speed Access
Corporation and TimeWarner. In addition, we believe that as a result of AT&T's
recent acquisition of Tele-Communications, Inc. and the proposed merger of
America Online, Inc. and Time Warner, cable TV networks will be used
increasingly for voice and high-speed data services.

  Fiber Optics. Fiber optic cables use pulses of light to transmit digital
information. Because fiber optic cables support thousands of high-speed, local
digital connections onto a single higher-speed connection to the central office
or the central side of the cable TV network where the video signals emanate,
they offer virtually unlimited bandwidth capacity. Due to their high capacity,
fiber optic cables are being used increasingly in the access network in both
telecommunications and cable TV applications.

  Signaling. Telephone systems require a signaling mechanism to set up and end
phone calls. These signals serve three basic functions: supervising or
monitoring the status of a line on circuit to see if it is busy, idle or
requesting service; alerting or indicating the arrival of an incoming call;
addressing or transmitting routing and destination signals over the network.
Signaling Systems 7, or SS7, is the standard signaling system used by telecom
networks worldwide. Signaling networks must support new access technologies to
ensure interoperability with the existing telephone network.

  We believe that the increasing demand for high-speed bandwidth access and the
increasing development and availability to end users of technologies, such as
those described above, that support this access will propel the continued
growth of the Internet and of network service providers. According to Ryan
Hankin Kent, Inc., at the end of 1999, 625,000 households and businesses in the
United States and Canada used DSL for broadband access and another 1.5 million
households used cable TV modems. Further, by 2003, the research indicates that
there will be 13.6 million DSL connections and 11.1 million cable TV modem
connections.

 Challenges of High-Speed Data Services Deployment

  Regardless of the type of technology, the successful deployment of high-speed
broadband services poses several major challenges to service providers.
Physical impairments in cable TV lines and the copper telephone wires upon
which DSL technology depends can degrade the quality of the broadband access
and,

                                       36
<PAGE>

in some cases, prevent any service from being delivered. Examples of physical
impairments include the following:

  .  shorts, which occur when the twisted pair conductors are touching each
     other or when one of them comes into contact with a grounded piece of
     metal;

  .  opens, which occur in a variety of ways including when a splice joining
     two cable segments fails or when a construction crew cuts through a
     buried cable;

  .  power crosses, which occur when the telephone wire comes into contact
     with a live AC power source; and

  .  wet cables, which occur when the aerial cable is subjected to rain or
     when the underground cable comes into contact with ground water and the
     pressurization system (if any) is inadequate to handle the leakage.

  In addition to the challenges stated above, asymmetric DSL, or ADSL, service
for residential end users faces its own particular challenges. ADSL is designed
to share the existing copper telephone wires using splitters or microfilters at
the customer premises and central office to break the single line into two
service appearances. Although a customer may have a working voice line, several
line impairments can kill ADSL service. These impairments include:

  .  load coils, which are inductors sometimes placed at 6000 foot intervals
     on telephone lines to optimize voice transmission;

  .  bridge taps, which occur when an existing spare telephone line to one
     customer location is "tapped" into prior to its endpoint to provide
     service to another location that has exhausted its supply of existing
     copper telephone lines, with the result that the line then has two
     separate customer ends, one at the original location and the other at
     the new location;

  .  AM radio interference, where the AM radio spectrum covers the same
     frequencies used in ADSL, high bit-rate DSL, or HDSL, high speed
     symmetric DSL, or SDSL, and T1 frequencies; and

  .  intra-cable crosstalk between high frequency service twisted pairs,
     where the twisted pairs act as long antennas placed in the same cable
     bundles, effectively transmitting onto one another creating excessive
     levels of background noise.

Because these problems may only be diagnosed and repaired effectively in the
field, many DSL service providers send field technicians to verify every line
before they hand over service to their customers.

  Cable TV and fiber optic networks face similar challenges. The cable TV
network was used originally to support one-way analog transmission of video
images. Now, digital cable TV networks also support voice and interactive high-
speed data services and customers require the same level of reliability as
provided by the existing telephone network. Potential problems for reliable and
high quality broadband access through cable TV lines include signal return path
interference and downstream signal degradation. As a result, cable TV providers
believe that cable plant pre-qualification and verification is a prerequisite
for the successful implementation of the technology. The widespread deployment
of fiber optic technologies into the cable TV and telecommunications access
networks also requires field verification equipment to verify and diagnose
service problems with these links.

 The Need for Service Verification Equipment

  In order to deploy successfully and maintain the new broadband networks,
service providers rely on sophisticated service verification equipment. This
equipment allows service providers to pre-qualify facilities for services,
verify proper operation of newly installed services and diagnose problems. In
addition, equipment manufacturers use service verification equipment to test
simulated networks during equipment

                                       37
<PAGE>

development and verify the successful production of equipment. Service
verification equipment can be grouped into three types: field verification,
remote testing and alarm and surveillance.

  Field Verification Equipment. Field verification equipment is used by all
service providers to probe the actual wires, cables or airwaves to verify that
a service works. In the case of a service malfunction, a field technician can
use the equipment to locate the exact fault so that repairs can be made.
Research and development labs, manufacturing departments and central office
technicians also use field verification equipment in their day-to-day
operations. Of the three types of service verification equipment, field
verification equipment delivers the most detailed service information and is
essential to the successful deployment of broadband networks. Service providers
have found field verification to be the most effective method to ensure that
the lines work as promised before they hand over service to their customers.

  Remote Test Equipment. Remote test equipment can help verify services and
identify certain types of service malfunctions from a centralized location. The
equipment is typically controlled by a centralized test system that automates
much of the remote testing process. It is commonly used to determine which
section within a 3,000 mile circuit has malfunctioned and to diagnose quickly
the nature of a customer's complaint. Due to its centralized and automated
nature, remote test equipment is an efficient way to complement field test
equipment in the deployment and maintenance of broadband networks.

  Alarm and Surveillance Equipment. Alarm and surveillance equipment constantly
monitors the telephone network, searching for facility or service degradations,
including outages. When a problem is noticed, a report may be sent immediately
to an automated trouble diagnostic system or to a human operator who interprets
the message and decides what further action is required. Corrective action
typically involves field verification or remote test equipment to identify and
correct specific problems.

  Because the competition for subscribers for high-speed bandwidth access is
intense, the quality and reliability of network service has become critical to
service providers because of the expense, loss of customers and negative
publicity resulting from poor service. Field technicians who use service
verification equipment allow service providers to verify and repair service
problems effectively and, thus, increase the quality and reliability of the
network. We believe that as broadband services are deployed further and as
competition for subscribers proliferates, service providers will increasingly
depend on advanced field test and monitoring solutions.

The Sunrise Solution

  We design and manufacture service verification equipment that enables service
providers to pre-qualify facilities for services, verify newly installed
services and diagnose problems relating to the new DSL services, fiber optic
and cable TV and signaling networks. Our products also enable equipment
manufacturers to test simulated networks during equipment development and
verify the successful production of equipment. Our products offer the following
features:

  .  Design Flexibility. We design our products to be flexible and to evolve
     as customer needs change. Our SunSet xDSL line, for example, allows
     field technicians the ability to upgrade their equipment easily through
     a variety of plug-in hardware modules. This flexible design allows the
     customer to adapt the test set to new DSL services and applications as
     network standards evolve, thereby protecting the customer's investment
     in the test equipment.

  .  Customer Driven Features. Each of our products is highly tailored to our
     customers' needs. Our marketing engineers continually interact with our
     customers during the design process to ensure that our products are the
     best available solution for them. For example, based on conversations
     with our customers, we delivered a pinging method for the technician to
     verify that a DSL line works the entire distance from the customer's
     premise to the Internet service provider.


                                       38
<PAGE>

  .  Handheld Design. We design most of our products to be used in the field.
     Most of our DSL and fiber optic products weigh less than three pounds
     and offer handheld convenience. The compact, lightweight design of these
     products enable field technicians to access problems and verify line
     operation quickly. The SunSet OCx for example, is the first handheld
     asynchronous transfer mode or ATM-compatible fiber optic field test set
     for SONET, or synchronous optical network, which is the North American
     standard for transmissions using fiber optics. Similarly, our new SunSet
     SDH will offer the same flexibility as the SunSet OCx for different
     international standards.

  Because of the design and functionality of our products, we provide the
following benefits to our customers:

  .  Rapid and Efficient DSL Deployment. Our products allow field and office
     technicians to test DSL lines rapidly and efficiently to ensure that
     they are properly connected to the central office and that they can
     support a specific type and speed of DSL service. In a single device,
     our products can be used to pre-qualify facilities for services,
     identify the source of problems and verify the proper operation of newly
     installed service before handing service over to customers.

  .  Improved Network Quality and Reliability. Field and office technicians
     use our products to diagnose and locate a variety of problems and
     degradations in broadband service. For example, our xDSL products allow
     extensive diagnosis and analysis of the physical layers of the copper
     wire network. This allows service providers to identify and repair
     problems and to restore service efficiently. As a result, our products
     support our customers' need to provide high quality and reliable
     service.

Strategy

  Our objective is to be a significant provider of service verification test
equipment for a broad range of applications within the global
telecommunications industry. The following are the key elements of our
strategy:

  .  Maintain Our Position in DSL Service Verification Equipment. We intend
     to maintain our position in DSL service verification equipment by
     continuing to enhance the features and functionality of our existing
     products to serve our customers' rapidly changing needs. In particular,
     we expect to introduce additional products to address new DSL
     technologies. We also plan to expand our relationships with the top DSL
     service providers in the United States and in international markets. In
     addition, we have recently begun to supply Lucent Technologies with a
     customized copper loop test head for their Stinger DSL Access
     Multiplexor product, which will provide service providers with a DSL
     test solution for DSL line deployment, maintenance and diagnostics
     functions.

  .  Penetrate the Growing Market for Fiber Optic Cable Verification Testing
     Equipment. We plan to capitalize on the expanding use of fiber optic
     cable in the telecommunications industry. For example, we have just
     introduced three new products to support testing of higher bandwidth
     fiber optic networks and plan to continue to increase the data rates
     supported by our optical products and develop additional products to
     support new network applications and technologies based on gigabit
     optical rates.

  .  Provide New Cable TV Verification Solutions. We intend to penetrate the
     growing market for verification equipment for cable TV by adding
     features and functionality to increase the applicability of our product
     offerings. For example, we have recently introduced our CR1200R, which
     provides for testing digital networks with Internet capabilities, and we
     expect to add new features in the future. Similarly, we intend to
     further address the convergence of voice and data across cable TV
     networks.

  .  Expand Beyond Field Verification Testing. We intend to leverage our
     expertise in field verification testing to expand into remote testing,
     alarm and surveillance and central office testing applications. Our
     Ghepardo signaling products allow technicians to remotely access
     signaling probes distributed throughout the network. In addition, our
     Ghepardo products provide alarm and surveillance

                                       39
<PAGE>

     monitoring and enable equipment developers to exercise and evaluate
     their network elements' signaling capabilities. We have also introduced
     products aimed at central office testing that are a natural extension of
     our field testing products. For example, the SS500 is a complete SONET
     service tester that offers a new combination of bi-directional protocol
     analysis and service verification for the central office, and our xDSL
     products offer the industry's only rack-mount verification solution for
     central office technicians.

  .  Grow Internationally. We plan to expand from our presence in over 60
     countries to meet the growing demand for high-speed access solutions and
     increase our brand recognition internationally. We believe existing
     service providers in Asia, Europe and Latin America will gradually
     convert their installed base of analog voice equipment to more efficient
     DSL equipment due to the advantages of the technology, its superior
     economics compared to readily available alternatives and the increasing
     demand for it. We plan to introduce a new fiber optics testing product,
     the Sunset SDH, which provides a combination of SONET/SDH for testing
     international gateway areas. We intend to add features to our existing
     products to make our solutions more attractive to service providers in
     other countries.

  .  Pursue Strategic Acquisitions. We plan to continue to make acquisitions
     and enter into joint ventures on a selected basis. We expect that
     acquisitions and joint ventures may provide an efficient way of
     expanding our business, product offerings and access to different
     customers and market niches.

  .  Pursue Follow-On Sales Opportunities. We plan to continue to develop
     hardware modules that allow our customers to increase the functionality
     of the products which they have purchased from us. For example, our xDSL
     products allow technicians to add hardware cartridges to test different
     types of DSL service. This feature allows customers to protect their
     investment in test equipment and generates follow-on sales opportunities
     as we develop new modules in the future.

Products

  We currently offer two main categories of service verification products:
broadband access service verification products and signaling testing products.

 Broadband Access Service Verification Products

  Our broadband access service verification products support a wide range of
access technologies, including DSL, cable TV and fiber optics, and within each
of these technologies, different transmission types, frequencies or speeds and
protocols for U.S. and international standards.

  We design our products to enable technicians to verify if a broadband service
has been properly installed and to help identify and correct problems in case
of an error. Our products are designed to be carried into the field by a
technician and offer a large graphical display, menu-driven functionality and
an easy-to-use interface. In addition, most of our DSL and fiber optic products
weigh less than three pounds, allowing field technicians to carry them easily.
Many of our new models support plug-in hardware modules that enable technicians
to upgrade our handheld test sets quickly and easily while in the field.

  Sales of our DSL products accounted for 100% of our net sales in 1997 and
1998 and approximately 97.5% in 1999. Although we have recently introduced or
acquired fiber optic, cable TV and signaling products, we expect that sales of
DSL products will continue to account for a substantial majority of our net
sales for the foreseeable future.

  We offer a three-year warranty on our DSL and fiber optic products sold in
the United States and a one-year warranty for those sold overseas with a two-
year extended warranty option at the time of sale. We offer a one-year warranty
on our cable TV and signaling products.

                                       40
<PAGE>

  Within our broadband access testing products, we manufacture service
verification equipment for three main technologies: DSL, cable TV and fiber
optics. We describe our major products in each product category below.

 DSL Products

 Global DSL          Global DSL products allow worldwide telecommunications
                     service providers to install and troubleshoot digital
                     copper-based circuits and services. The xDSL series
                     finds data transmission rates and noise margins that can
                     be supported by the line. This series employs modules to

 Signaling Testing Products

  We recently introduced Ghepardo, a new product line for signaling testing and
analysis. Our signaling products are designed for the central office to analyze
major signaling protocols, including SS7, and standard data communication
protocols. We design our products on an open platform with hardware and
software that users can customize easily. Our web-based user interface allows
users to control our products, including customization of test functions, from
anywhere in the world through standard web-browser software.

Customers

  Our customers include telecommunications service providers, network
infrastructure suppliers and installers, technicians and engineers in North
America, Latin America, Europe and the Asia/Pacific region. The following is a
selected list of companies who purchased in excess of $500,000 of our products
during 1999. Each of these companies accounted for 1% or more of our net sales
in 1999.

  AT&T Corp./TCI Communications,         Rhythms NetConnections Inc.
   Inc.                                  SBC Communications Inc.
  Bell Atlantic Corporation               (consisting of Ameritech
  BellSouth Telecom, Inc.                 Corporation, Nevada Bell,
  Chunghwa Telecom Co., Ltd.              Pacific Bell, Southern New
  France Telecom                          England Telephone and
  Korea Telecom                           Southwestern Bell Telephone
  Nippon Telegraph and Telephone          Company)
   Corporation                           Sprint Corporation
  NorthPoint Communications Group,       Teligent, Inc.
   Inc.                                  Telkom SA, Ltd.

As of March 31, 2000, we had sold versions of our products to over 1,800
customers in over 60 countries. In 1999, affiliates of SBC Communications
accounted for approximately 40.6% of our net sales. Besides SBC Communications
in 1999, no individual customer accounted for 10% or more of our net sales in
1997, 1998 or 1999. We expect that we will continue to depend upon a relatively
limited number of customers for substantially all of our revenues in future
periods. See "Risk Factors--Risks Relating to Our Business--Customer
Concentration."

Sales, Marketing and Customer Service

  Sales. We sell our products to telecommunications service providers, network
infrastructure suppliers and installers, technicians and engineers through
manufacturers' representatives, independent distributor organizations and our
direct sales force.

  In the United States, we sell our products through 13 manufacturers'
representatives companies who are supported by our in-house direct sales force.
Manufacturers' representatives are paid on a commission basis to sell our
products and have exclusive rights in their respective regions. Our
manufacturers' representatives solicit orders from the customer, and we ship
our products directly to the customer. We pay commissions once payment is
received from the customer. Our direct sales force consists of 13 employees who
focus on sales in the United States, including a team of regional sales
managers who direct the efforts of our manufacturers' representatives, regional
account managers who focus on specific accounts within a region and our Vice
President of North American Sales, who directs the sales effort in North
America.

  Outside the United States, we sell our products through 64 independent
distributor organizations, which are directed by our regional directors of
marketing and sales. Once a sale is made, we sell our product to the
distributor who then resells the product to the end user. We sell our products
to our independent distributor organizations at a discount off our list price.
The Asia/Pacific region is directed by our Vice President of Strategic
Marketing. International sales were $13.5 million or approximately 46% of our
net sales in 1997, $12.0 million or approximately 42% in 1998 and $12.2 million
or approximately 20% in 1999.

                                       43
<PAGE>

We expect that international sales will continue to account for a significant
portion of our net sales in future periods. In addition to our network of
international distributors, we have sales people located in Beijing, China and
Modena, Italy and plan to open new offices in other locations in the future.
See "Risk Factors--Risks Relating to Our Business--Risks of International
Operations." For information regarding export sales and international
operations, see Note 14 of notes to consolidated financial statements of
Sunrise.

  We sell our products predominantly to large telecommunications service
providers. These prospective customers generally commit significant resources
to an evaluation of our and our competitors' products and require each vendor
to expend substantial time, effort and money educating the prospective customer
about the value of the vendor's solutions. Consequently, sales to this type of
customer generally require an extensive sales effort throughout the prospective
customer's organization and final approval by an executive officer or other
senior level employee. The result is lengthy sales and implementation cycles,
which make sales forecasting difficult. In addition, even after a large
telecommunications service provider has approved our product for purchase,
their future purchases are uncertain because we do not enter into long-term
supply agreements or requirements contracts with those parties. Delays
associated with potential customers' internal approval and contracting
procedures, procurement practices, testing and acceptance processes are common
and may cause potential sales to be delayed or foregone. As a result of these
and related factors, the sales cycle of new products for large customers
typically ranges from six to 24 months.

  Marketing. We market and promote sales of our products by the following
activities:

  .  Our product marketing group researches new opportunities, prepares
     product definitions with our research and development group and defines
     new features to create new products;

  .  The overall marketing group hosts a variety of seminars several times a
     year in the United States, Asia, Europe and Latin America to improve the
     sales effectiveness of our manufacturers' representatives and
     international distributors;

  .  Our product marketing engineers, regional sales managers and account
     managers travel extensively with our manufacturers' representatives and
     international distributors to develop new product opportunities with
     customers and to support their presentations;

  .  The marketing communications group maintains a public Web site,
     publishes brochures and specification sheets and generates press
     releases and publicity to increase our recognition in the
     telecommunications industry;

  .  Our technical publications group prepares user's manuals, field manuals,
     quick reference guides, and product operation videos to serve the needs
     of our users;

  .  Our training department prepares customer training presentations and
     sponsors Sunrise University, a factory-based xDSL training program for
     our customers.

  Customer Service. We believe that customer service following the sale of our
products is a critical ingredient to our success. We provide customer service
in numerous ways, including:

  .  providing rapid instrument repair services;

  .  operating a 24 hour per day telephone support line to help customers who
     are having difficulty using our products in their particular
     application;

  .  maintaining a proprietary Web site containing on-line, up-to-the-minute
     product repair information for our distributors' international repair
     centers, with a factory-certified technician training program for our
     distributors' international repair center technicians; and

  .  measuring the satisfaction of our customers and communicating this
     information to our quality group.

                                       44

Research and Development

  We have assembled a team of highly skilled engineering professionals who are
experienced at designing telecommunications service verification test
equipment. Our engineering personnel have expertise in a number of fields,
including interfacing test equipment with digital loop carrier, voice and data
switching technology, local loop equipment and operations support systems. We
spent approximately $5.9 million on research and development in 1997, $6.2
million in 1998 and $10.7 million in 1999. Research and development represents
our largest direct employment expense. At March 31, 2000, we had a total of 89
employees engaged in research and development in San Jose, California;
Norcross, Georgia; Springfield, Virginia; and Modena, Italy.

  We believe that our continued success depends on our ability to anticipate
and respond to changes in the telecommunications industry and anticipate and
satisfy our customers preferences and requirements. Accordingly, we
continually review and evaluate technological and regulatory changes affecting
the telecommunications industry and seek to offer products and capabilities
that solve customers' operational challenges and improve their efficiency. In
general, we spend anywhere from two months to four years developing a new
product.

Regulations and Industry Standards

  Our products are designed to comply with a significant number of industry
standards and regulations, some of which are evolving as new technologies are
deployed. In the United States, our products must comply with various
regulations defined by the Federal Communications Commission and Underwriters
Laboratories as well as industry standards established by Telcordia
Technologies, Inc., formerly Bellcore, and the American National Standards
Institute. Internationally, our products must comply with standards
established by the European Committee for Electrotechnical Standardization,
the European Committee for Standardization, the European Telecommunications
Standards Institute, telecommunications authorities in various countries as
well as with recommendations of the International Telecommunications Union.
The failure of our products to comply, or delays in compliance, with the
various existing and evolving standards could negatively impact our ability to
sell our products.

Manufacturing

  Our production process consists of planning, procurement, fabrication,
rework, system assembly, system final test, software option customization and
shipping. We purchase substantially all parts, including resistors, integrated
circuit boards, LCDs and printed circuit boards, from distributors and
manufacturers worldwide. We package these parts into kits and send them to
contract manufacturers to assemble them into printed circuit boards. We
perform substantially all remaining manufacturing operations. We maintain
sourcing and manufacturing operations in San Jose, California; Norcross,
Georgia; Taipei, Taiwan and Modena, Italy. In 1999, we performed the majority
of sourcing and nearly all contract manufacturing and final assembly in San
Jose, California. We have obtained ISO-9001 certification for our San Jose
operations.

  In 1998, we formed a subsidiary in Taiwan, Taiwan Sunrise Telecom Company
Limited, as a turn-key manufacturer and local procurement operation. We also
own an equity interest of approximately fifteen percent in Top Union, an
assembly company located in Taipei, Taiwan that performs module assembly as
part of the Taiwan Sunrise Telecom turn-key operation. We intend to increase
the use of outsource manufacturing for our more mature products. We believe
that outsourcing will lower our manufacturing costs, in particular our labor
costs, provide us with more flexibility to scale our operations to meet
changing demand and allow us to focus our engineering resources on new product
development and product enhancements.

  In our manufacturing process, we purchase many key products, such as
microprocessors, bus interface chips, optical components and oscillators, from
a single source or from that product's sole supplier. We rely exclusively on
third-party subcontractors to manufacture certain sub-assemblies and we have
retained, from time to time, third party design services in the development of
our products. We do not have long-term

                                      45
<PAGE>

supply agreements with these vendors. In general, we make advance purchases of
some products and components to ensure an adequate supply, particularly for
products that require lead times of up to six months to manufacture. For a
discussion of the risks associated with our reliance on these third parties,
see "Risk Factors--Risks Relating to Our Business--Dependence on Sole and
Single Source Suppliers."

Competition

  The market for field verification test equipment is fragmented and intensely
competitive, both in and outside the United States, and is subject to rapid
technological change, evolving industry standards and regulatory developments.
We compete with a number of United States and international suppliers that vary
in size and in the scope and breadth of the products and services offered. The
following table sets forth our principal competitors in each of our product
categories.

<TABLE>
<CAPTION>
Product Category         Principal Competitors
----------------         ---------------------
<S>                      <C>
Digital Subscriber Line  TTC (a division of Dynatech, Inc.) and Agilent Technologies, Inc.
Fiber Optics SONET/SDH   Digital Lightwave, Inc., TTC and Agilent Technologies, Inc.
Cable TV                 Wavetek Wandel Golterman, Inc. and Agilent Technologies, Inc.
Signaling                Inet Technologies, Inc. and GN Nettest
</TABLE>

  On February 14, 2000, Dynatech and Wavetek announced the merger of TTC to
Wavetek, which could have the effect of making the combined company a more
formidable competitor. We expect that, as our industry and market evolves, new
competitors or alliances among competitors could emerge and acquire significant
market share. We anticipate that competition in our market will increase with
the result that we will face greater threats to our market share, price
pressure on our products and the likelihood that, over time, our profitability
may decrease.

  We believe that the principal competitive factors in our market include:

  .  a continued high level of investment in research and development and
     marketing;

  .  speed of new product introductions to market;

  .  depth of product functionality;

  .  ease of installation, integration and use;

  .  system reliability and performance;

  .  price and financing terms;

  .  technical support and customer service;

  .  size and stability of the vendor's operations; and

  .  compliance with government and industry standards.

Intellectual Property and Proprietary Technology

  Our intellectual property, including our proprietary technology, processes
and know-how, trade secrets, patents, trademarks and copyrights, is important
to our business and to our continued success. We have one patent for a handheld
communications tester, and we have filed several applications for additional
patents with the U.S. Patent and Trademark Office. Our research and development
and manufacturing process typically involves the use and development of a
variety of forms of intellectual property and proprietary technology, although
no one form of this intellectual property and proprietary technology is
material to our business. In addition, we incorporate software that we license
from several third party sources into our products. These licenses generally
renew automatically on an annual basis. We believe that alternative
technologies for this licensed software are available both domestically and
internationally.


                                       46
<PAGE>

  We protect our proprietary technology by:

  .  relying on intellectual property law, including patent, trade secret,
     copyright and trademark law and by initiating litigation where necessary
     to enforce our rights;

  .  limiting access to our software, documentation and other proprietary
     information; and

  .  entering into confidentiality agreements with our employees.

  We may receive in the future notices from holders of patents that raise
issues as to possible infringement by our products. As the number of
telecommunications test, measurement, and network management products increases
and the functionality of these products further overlaps, we believe that we
may become subject to allegations of infringement given the nature of the
telecommunications industry and the high incidence of these kinds of claims.
Questions of infringement and the validity of patents in the field of
telecommunications technologies involve highly technical and subjective
analyses. These kinds of proceedings are time consuming and expensive to defend
or resolve, result in substantial diversion of management resources, cause
product shipment delays or could force us to enter into royalty or license
agreements rather than dispute the merits of the proceeding initiated against
us. For more information regarding the risks to our intellectual property, see
"Risk Factors--Risks Relating to Our Business--Intellectual Property Risks."

Employees

  At March 31, 2000, we had a total of 228 full-time employees, consisting of
184 in the United States, 21 in Taiwan and 23 in Italy, and approximately 35
temporary employees. Of the total permanent employees, 89 were engaged in
research and development, 50 were engaged in sales, marketing and customer
support, 62 were engaged in operations and 27 were engaged in administration
and finance. None of our employees is subject to a collective bargaining
agreement. The employees of our Pro.Tel subsidiary are protected by certain
provisions of Italian law. We believe that our relations with our employees are
good. See "Risk Factors--Risks Relating to Our Business--Need for New
Personnel" and "--Dependence on Key Employees."

Legal Proceedings

  We are not currently a party to any material legal proceedings. In September
1999, the United States District Court for the Northern District of California
entered final judgment against Electrodata, Inc. stating that it had literally
infringed our U.S. Patent No. 5,619,489, entitled Handheld Communications
Tester. The court also entered judgment against Electrodata that the claims at
issue were valid and the patent was enforceable. Electrodata has filed a notice
of appeal with the United States Court of Appeals for the Federal Circuit. We
do not believe that the outcome of this appeal will materially impact our
business.

Facilities

  Our current headquarters and manufacturing facility occupies approximately
47,000 square feet in San Jose, California under a lease that expires in
November 2004. We have contracted to build near our current headquarters a new
91,700 facility, which we are building to accommodate our need for an increase
in manufacturing capacity and employees. The new facility is scheduled for
completion in late 2000. We also lease approximately 7,500 square feet of
office and manufacturing space in Norcross, Georgia; approximately 7,300 square
feet of office space in Springfield, Virginia, approximately 10,000 square feet
of office and manufacturing space in Modena, Italy, 10,000 square feet of
office space in Taipei, Taiwan and a liaison office in Beijing, China.

---------------------
(1) All options granted to Mr. Eidelman vest annually in four equal
    installments beginning one year after the date of grant.
(2) Realizable values are reported net of the option exercise price. The dollar
    amounts under these columns are the result of calculations at the 5% and
    10% rates (determined from the initial offering price of $15.00, not the
    stock's current market value) set by the Securities and Exchange Commission
    and therefore are not intended to forecast possible future appreciation, if
    any, of Sunrise's stock price. Actual gains, if any, on stock option
    exercises are dependent on the future performance of the common stock as
    well as the optionholder's continued employment through the vesting period.
    The potential realizable value calculation assumes that the optionholder
    waits until the end of the option term to exercise the option.

Option Exercises and Holdings

  The following table provides summary information concerning the shares of
common stock acquired in 1999, the value realized upon exercise of stock
options in 1999, and the year end number and value of unexercised options with
respect to each of the officers listed in the summary compensation table as of
December 31, 1999. The value was calculated by determining the difference
between the fair market value of underlying securities and the exercise price.
The fair market value of our common stock at December 31, 1999 was assumed to
be $5.00 per share.

Benefit Plans

  1993 Stock Option Plan. Our 1993 stock option plan was adopted by our board
of directors in December 1993 and approved by our stockholders in April 1994.
In 1995, our board amended and restated the 1993 stock option plan and our
stockholders approved the amended and restated plan in April 1996. Our 1993
stock option plan provides for the granting to employees of incentive stock
options within the meaning of Section 422 of the Internal Revenue Code and of
nonstatutory stock options. A total of 5,250,000 shares has been reserved for
issuance under the 1993 stock option plan. As of March 31, 2000, options to
purchase an aggregate of 2,796,198 shares of our common stock were outstanding
under our 1993 stock option plan. Nonqualified options generally become vested
and exercisable over a four year period in equal annual installments and expire
ten years from the date of grant. Incentive stock options generally are
exercisable upon grant; provided, however, that no incentive stock options are
still outstanding from a prior grant. In the event of a stock split or stock
dividend the board may appropriately adjust the number, kind and price of the
shares subject to outstanding options to reflect such a change. In the event of
an acquisition of Sunrise, including a merger or sale of assets, options will
generally terminate, unless the merger agreement provides for the assumption of
the stock option agreements executed pursuant to the plan. Upon the exercise of
an option, shares may be subject to transfer restrictions, as defined in the
stock option agreement, including the right of first refusal and the right to
repurchase the stock. Our board of directors has determined that no further
options will be granted under the 1993 stock option plan after this offering.

  2000 Stock Plan. Our 2000 stock plan was adopted by our board of directors
and approved by our stockholder in April 2000. The 2000 stock plan will become
effective upon our initial public offering. At that time, all outstanding
shares reserved under our 1993 stock option plan will be merged into the
reserved share pool of the 2000 stock plan. All outstanding options under the
1993 stock option plan will continue to be administered according to the terms
and conditions of the stock option agreements issued pursuant to that plan. In
the event that an option expires after this offering without being exercised,
any remaining shares reserved for the option grant under the 1993 stock option
plan will return to the reserved share pool of the 2000 stock plan.

  The 2000 stock plan provides for the discretionary grant of incentive stock
options to employees, including officers and employee directors, and for the
discretionary grant of nonstatutory stock options and stock purchase rights to
employees, directors and consultants. The 2000 stock plan also provides for the
periodic automatic grant of nonstatutory stock options to non-employee
directors.

  The total shares of common stock currently reserved for issuance under the
2000 stock plan equals 3,750,000 shares of common stock plus the number of
shares that remain reserved for issuance under the 1993 stock option plan as of
the date the 2000 stock plan became effective.

  In addition, commencing on the first day of our next fiscal year, shares will
be added to the 2000 stock plan annually equal to the least of

  . 2 1/2% of the outstanding shares on the last day of the prior fiscal
    year;

  . 1,300,000 shares; and

  . such lower amount as the board may determine.

  Unless terminated sooner, the 2000 stock plan will terminate automatically 10
years from its effective date.

  Our compensation committee, which generally administers our 2000 stock plan,
has the power to determine the terms of the options or stock purchase rights
granted, including the exercise price of the option or restricted stock grant;
the number of shares subject to each option or restricted stock grant; the
vesting and exercise forms of each option or stock purchase right; and the form
of consideration payable upon the exercise of each option or stock purchase
right.

  Under the 2000 stock plan non-employee directors receive annual grants of
nonstatutory stock options. As of the date of this prospectus non-employee
directors will receive a grant of an option to purchase shares with a fair
market value of $25,000 on the grant date. Non-employee directors who first
join our board after the date of this prospectus will receive an initial grant
when they join the board. In addition, all non-employee directors will receive
a grant of an option to purchase shares with a fair market value equal to
$25,000 on the grant date at each subsequent annual meeting, provided they will
continue to serve on the board after such annual meeting. Non-employee director
options will have a term of ten years but will expire within 90 days of the
directors termination of service or one year if such termination is due to
death or disability. Non-employee director options vest one year from the date
of grant, provided the director continues to serve as a director at that time.

  In addition, the board has the authority to amend, suspend or terminate the
2000 stock plan, so long as no such action affects any shares of common stock
previously issued and sold or any option previously granted under the plan. The
maximum number of option shares each optionee may be granted during a fiscal
year is 600,000 shares. However, in connection with an optionee's initial
service with us, such optionee may be granted up to a total of 900,000 shares
during the initial fiscal year of service. Restricted stock grants are limited
to 75,000 shares per person in any fiscal year.

  Options and restricted stock granted under our 2000 stock plan are generally
not transferable by the participant, and each option is exercisable during the
lifetime of the optionee and only by such optionee.

  In the case of restricted stock, unless the compensation committee determines
otherwise, the restricted stock purchase agreement shall grant Sunrise a
repurchase option exercisable after the purchaser's employment or consulting
relationship with Sunrise has ended for any reason, including death or
disability. The purchase price for shares repurchased pursuant to the
restricted stock purchase agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to Sunrise. The repurchase option shall lapse at a rate determined by the
compensation committee.

  The exercise price of all incentive stock options and nonstatutory stock
options granted automatically to non-employee directors must be at least equal
to the fair market value of the common stock on the date of grant. The exercise
price of other nonstatutory stock options and stock purchase rights granted
under the 2000 stock plan is determined by the administrator, but with respect
to nonstatutory stock options intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Internal Revenue
Code, the exercise price must be at least equal to the fair market value of our
common stock on the date of grant. With respect to any participant who owns
stock possessing more than 10% of the voting power of all classes of our
outstanding capital stock, the exercise price of any incentive stock option
granted must at least equal 110% of the fair market value on the grant date and
the term of such incentive stock option must not exceed five years. The term of
all other options granted under the 2000 stock plan may not exceed ten years.

  The 2000 stock plan provides that in the event that we are acquired by
another corporation, or sell substantially all of our assets, each option and
stock purchase right may be assumed or an equivalent option substituted for by
the successor corporation. If the outstanding options and stock purchase rights
are not assumed or substituted for by the successor corporation, the stock
option agreements made under the 2000 stock plan may provide that the option
holder will fully vest in and have the right to exercise the option as to all
of the optioned stock, or that the repurchase option of a restricted stock
grant may lapse, including shares to which the holder would not otherwise be
entitled.

  2000 Employee Stock Purchase Plan. Our 2000 employee stock purchase plan was
adopted by our board of directors and approved by our stockholder in April
2000. A total of 600,000 shares of our common stock has been reserved for
issuance under the 2000 purchase plan, plus annual increases equal to the least
of

  .  0.75% of the outstanding shares on the last day of the prior fiscal
     year;

                                       54
<PAGE>

  .  300,000 shares; and

  .  such lower amount as the board may determine.

  Under the 2000 purchase plan, which is intended to qualify under Section 423
of the Internal Revenue Code, our board of directors may determine the duration
and frequency of stock purchase periods. Initially the plan will operate using
consecutive, overlapping, twenty-four month offering periods. Each offering
period will include four six-month purchase periods. The offering periods
generally start on the first trading day on or after May 15 and November 15 of
each year, except for the first such offering period which commences on the
first trading day on or after the effective date of this offering and ends on
the last trading day on or before November 14, 2000.

  Employees of Sunrise or of any participating subsidiaries are eligible to
participate. However, employees may not be granted an option to purchase stock
under the 2000 purchase plan if they, immediately after the grant, own stock
possessing 5% or more of the total combined voting power or value of all
classes of our capital stock.

  The 2000 purchase plan permits participants to purchase our common stock
through payroll deductions of up to 15% of their total base compensation,
excluding bonuses, commissions and overtime, not to exceed $25,000 in any plan
year. In addition, no more than 0.5% of the outstanding shares of the company
may be sold under the plan on any purchase date, and no more than 1% of the
outstanding shares may be sold in any calendar year.

  Amounts deducted and accumulated by the participant are used to purchase
shares of common stock at the end of each purchase period. The price of stock
purchased under the 2000 purchase plan is generally 85% of the lower of the
fair market value of the common stock either at the beginning of the offering
period or at the end of the purchase period. Rights to purchase stock under the
2000 purchase plan expire on the earlier of

  .  27 months after the date of grant;

  .  the option period as determined by the board at the time of grant; or

  .  the employee's termination of employment.

  In the event the fair market value at the end of a purchase period is less
than the fair market value at the beginning of the offering period, the
participants will be withdrawn from the current offering period following
exercise and automatically re-enrolled in a new offering period. Participants
may end their participation at specified times during an offering period, and
they will be paid their payroll deductions to date. Participation ends
automatically upon termination of employment with Sunrise.

  Rights granted under the 2000 purchase plan are not transferable by a
participant other than upon death or by a special determination by the plan
administrator. Each outstanding option under the 2000 purchase plan will be
subject to the acquisition agreement in the event we merge with or into another
corporation or sell substantially all of our assets.

  Our board of directors has the authority to amend or terminate the 2000
purchase plan at any time and for any reason. If the board of directors
terminates the plan during an offering period, the board may terminate all
outstanding rights either upon termination of the plan, upon completion of the
purchase of shares on the next purchase date, or may elect to permit rights to
expire according to their terms. Notwithstanding anything to the contrary, the
board of directors may in its sole discretion amend the 2000 purchase plan to
the extent necessary and desirable to avoid unfavorable financial accounting
consequences by altering the purchase price for any offering period, shortening
any offering period or allocating remaining shares among the participants.
Unless earlier terminated by our board of directors, the 2000 purchase plan
will terminate automatically ten years from its effective date.

                       PRINCIPAL AND SELLING STOCKHOLDERS

  The following table sets forth information regarding the beneficial ownership
of our common stock as of March 31, 2000 and as adjusted to reflect the sale of
the common stock offered by Sunrise by this prospectus by:

  .  each of our directors and the officers listed in the summary
     compensation table;

  .  all directors and executive officers as a group;

  .  each person who is known to us to own beneficially more than 5% of its
     common stock; and

  .  each of the selling stockholders.

  Except as otherwise noted, the address of each person listed in the table is
c/o Sunrise Telecom Incorporated, 22 Great Oaks Boulevard, San Jose, California
95119. The table includes all shares of common stock issuable within 60 days of
March 31, 2000 upon the exercise of options and other rights beneficially owned
by the indicated stockholders on that date. Beneficial ownership is determined
in accordance with the rules of the Securities and Exchange Commission and
includes voting and investment power with respect to shares. To our knowledge,
except under applicable community property laws or as otherwise indicated, the
persons named in the table have sole voting and sole investment control
regarding all shares beneficially owned. The applicable percentage of ownership
for each stockholder is based on 45,778,401 shares of common stock outstanding
as of March 31, 2000, together with applicable options for that stockholder.
Shares of common stock issuable upon exercise of options and other rights
beneficially owned were deemed outstanding for the purpose of computing the
percentage ownership of the person holding these options and other rights, but
are not deemed outstanding for computing the percentage ownership of any other
person.

                              CERTAIN TRANSACTIONS

  Since January 1, 1997, we have not been involved in any transaction or series
of similar transactions to which we were or are a party in which the amount
involved exceeded or exceeds $60,000 and in which any of our directors or
executive officers, any holder of more than 5% of any class of our voting
securities or any member of the immediate family of any of the foregoing
persons had or will have a direct or indirect material interest, other than the
transactions described below.

Insider Transactions

  Paul Ker-Chin Chang, our Chief Executive Officer and President, is the owner
of Telecom Research Center. We purchased equipment from Telecom Research Center
used in our manufacturing process totaling $58,000 in 1999, $84,000 in 1998 and
$81,000 in 1997. At December 31, 1999, 1998 and 1997, there was no accounts
payable due to Telecom Research Center. The terms of these transactions were
negotiated at arms length and are similar to those of unrelated parties.

  In June 1997, we repurchased shares of our common stock at a price of $1.10
per share from certain of our stockholders, including:

  .  3,000 shares from Bruce and Molly Mastic, a brother-in-law and sister of
     Paul Marshall, our Chief Operating Officer;

  .  60,000 shares from Robert and Pat Pfeiffer, the parents of Robert C.
     Pfeiffer, our Chief Technology Officer; and

  .  15,000 shares from Ann Filson, a sister of Paul Marshall, our Chief
     Operating Officer.

  In May 1998, we repurchased shares of our common stock at a price of $1.43
per share from certain of our stockholders, including:

  .  15,000 shares from Andrew and Mary Marshall, the parents of Paul
     Marshall, our Chief Operating Officer; and

  .  52,500 shares from Bryant Blewett and Ellen Marshall, a brother-in-law
     and a sister of Paul Marshall, our Chief Operating Officer.

  During 1997, 1998 and 1999, we retained the law firm of Littler Mendelson to
perform legal services for us. Ms. Walt, a director of Sunrise and a member of
the Compensation Committee, is a shareholder in Littler Mendelson.

  Mr. Huff, a director of Sunrise, was the Chief Financial Officer of
NorthPoint Communications from June 1998 until April 2000. We sold
approximately $590,000 of products to NorthPoint Communications in 1999 and
$192,000 in 1998.

  Creative Technologies Ltd., the parent of Digicom Systems Inc., has been
allocated 270,000 shares in the initial public offering. Patrick Peng-Koon Ang,
a director of Sunrise, is the President of Digicom Systems Inc.

Agreements with Management

  We have entered into indemnification agreements with our officers and
directors containing provisions which may require us, among other things, to
indemnify our officers and directors against certain liabilities that may arise
by reason of their status or service as officers or directors (other than
liabilities arising from willful misconduct of a culpable nature) and to
advance their expenses incurred as a result of any proceeding against them as
to which they could be indemnified. See "Description of Capital Stock--
Indemnification Provisions."

                                       58
<PAGE>

                          DESCRIPTION OF CAPITAL STOCK

  Upon the completion of this offering, Sunrise will be authorized to issue
175,000,000 shares of common stock, $.001 par value per share, and 10,000,000
shares of undesignated preferred stock, $.001 par value per share.

Common Stock

  At March 31, 2000, there were 45,778,401 shares of common stock outstanding,
which includes 500,001 shares of common stock issued subject to a put option,
which expired on May 22, 2000, as part of the Pro.Tel acquisition, held of
record by 90 stockholders. Options to purchase 2,796,198 shares of common stock
were also outstanding. There would be 49,595,829 shares of common stock
outstanding as of March 31, 2000 (assuming no exercise of outstanding options
under Sunrise's stock option plans after March 31, 2000) after giving effect to
the sale of the shares offered hereby.

  The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. Subject to
preferences that may be applicable to any outstanding preferred stock, holders
of common stock are entitled to receive ratably such dividends as may be
declared by the Board of Directors out of funds legally available for that
purpose. See "Dividend Policy." In the event of liquidation, dissolution or
winding up of Sunrise, the holders of common stock are entitled to share
ratably in all assets remaining after payment of liabilities, subject to the
prior distribution rights of any outstanding preferred stock. The common stock
has no preemptive or conversion rights or other subscription rights.

Preferred Stock

  There are currently no outstanding shares of preferred stock. Upon the
closing of this offering, the Board of Directors will have the authority,
without further action by the stockholders, to issue up to 10,000,000 shares of
preferred stock, $.001 par value, in one or more series. The Board of Directors
will also have the authority to designate the rights, preferences, privileges
and restrictions of each such series, including dividend rights, dividend
rates, conversion rights, voting rights, terms of redemption, redemption
prices, liquidation preferences and the number of shares constituting any
series.

  The issuance of preferred stock may have the effect of delaying, deferring or
preventing a change in control of Sunrise without further action by the
stockholders. The issuance of preferred stock with voting and conversion rights
may also adversely affect the voting power of the holders of common stock. In
certain circumstances, an issuance of preferred stock could have the effect of
decreasing the market price of the common stock. As of the closing of the
offering, no shares of preferred stock will be outstanding. Sunrise currently
has no plans to issue any shares of preferred stock.

Delaware Anti-Takeover Law and Charter and Bylaw Provisions

  Provisions of Delaware law and our charter documents could make the
acquisition of our company and the removal of incumbent officers and directors
more difficult. These provisions are expected to discourage certain types of
coercive takeover practices and inadequate takeover bids and to encourage
persons seeking to acquire control of our company to negotiate with it first.
We believe that the benefits of increased protection of its potential ability
to negotiate with the proponent of an unfriendly or unsolicited proposal to
acquire or restructure Sunrise outweigh the disadvantages of discouraging such
proposals because, among other things, negotiation of such proposals could
result in an improvement of their terms.

  Section 203. We are subject to the provisions of Section 203 of the Delaware
law. In general, the statute prohibits a publicly-held Delaware corporation
from engaging in a "business combination" with an "interested stockholder" for
a period of three years after the date that the person became an interested
stockholder unless, subject to exceptions, the business combination or the
transaction in which the person

                                       59
<PAGE>

became an interested stockholder is approved in a prescribed manner. Generally,
a "business combination" includes a merger, asset or stock sale, or other
transaction resulting in a financial benefit to the stockholder. Generally, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years prior, did own, 15% or more of the
corporation's voting stock. These provisions may have the effect of delaying,
deferring or preventing a change in control of Sunrise without further action
by the stockholders.

  Special Stockholder Meetings. Our restated certificate of incorporation
provides that special meetings of the stockholders for any purpose or purposes,
unless required by law, may only be called by the board of directors, the
Chairman of the Board, if any, and the President. This limitation on the
ability to call a special meeting could make it more difficult for stockholders
to initiate actions that are opposed by the board. These actions could include
the removal of an incumbent director or the election of a stockholder nominee
as a director. They could also include the implementation of a rule requiring
stockholder ratification of specific defensive strategies that have been
adopted by the board with respect to unsolicited takeover bids. In addition,
the limited ability to call a special meeting of stockholders may make it more
difficult to change the existing board and management.

  Classified Board of Directors. Our board will be divided into three classes
of directors serving staggered three-year terms. As a result, approximately
one-third of the board of directors will be elected each year. These provision
are likely to increase the time required for stockholders to change the
composition of our board of directors. For example, in general at least two
annual meetings will be necessary for stockholders to effect a change in the
majority of our board of directors. Subject to the rights of the holders of any
outstanding series of preferred stock, the certificate of incorporation
authorizes only the board of directors to fill vacancies, including newly
created directorships. The certificate of incorporation also provides that
directors may be removed by stockholders only for cause and only by affirmative
vote of holders of two-thirds of the outstanding shares of voting stock.

  Supermajority Vote to Amend Charter and Bylaws. Our restated certificate of
incorporation and restated bylaws each provide that our bylaws may only be
amended by a two-thirds vote of the outstanding shares. In addition, our
certificate of incorporation provides that its provisions related to bylaw
amendments, staggered board and indemnification may only be amended by a two-
thirds vote of the outstanding shares.

  No Stockholder Action by Written Consent. Our restated certificate of
incorporation provides that stockholder action can be taken only at an annual
or special meeting of stockholders and may not be taken by written consent.

  Advance Notice Procedures. Our restated bylaws provide for an advance notice
procedure for the nomination, other than by or at the direction of our board of
directors, of candidates for election as directors as well as for other
stockholder proposals to be considered at annual meetings of stockholders.

Indemnification Provisions

  As permitted by the Delaware General Corporation Law, our certificate of
incorporation eliminates the personal liability of our officers and directors
for monetary damages for breach or alleged breach of their fiduciary duties as
officers or directors, other than in cases of fraud or other willful
misconduct. In addition, our by-laws provide that we are required to indemnify
our officers and directors even when indemnification would otherwise be
discretionary, and we are required to advance expenses to our officers and
directors as incurred in connection with proceedings against them for which
they may be indemnified. We have entered into indemnification agreements with
our officers and directors containing provisions that are, in some respects,
broader than the specific indemnification provisions contained in the Delaware
General Corporation Law. The indemnification agreements require us to indemnify
our officers and directors against liabilities that may arise by reason of
their status or service as officers and directors and to advance their expenses
incurred as a result of any proceeding against them as to which they could be
indemnified.

                                       60
<PAGE>

  At present, we are not aware of any pending or threatened litigation or
proceeding involving a director, officer, employee or agent of Sunrise in which
indemnification would be required or permitted. We are not aware of any
threatened litigation or proceeding that might result in a claim for
indemnification. We believe that our charter provisions and indemnification
agreements are necessary to attract and retain qualified persons as directors
and officers.

  The transfer agent and registrar for our common stock is Computershare Trust
Company, Inc. The transfer agent's address and telephone number is 12039 W.
Alameda Parkway, Suite Z2, Lakewood, Colorado 80228 and (303) 984-4110.

                        SHARES ELIGIBLE FOR FUTURE SALE

  Upon completion of this offering, we will have outstanding 49,595,829 shares
of common stock based upon shares outstanding at March 31, 2000. Excluding the
4,000,000 shares of common stock offered hereby and assuming no exercise of the
underwriters' over-allotment option, as of the effective date of the
registration statement, there will be 45,595,829 shares of common stock
outstanding, all of which are "restricted" shares under the Securities Act of
1933.

  The following table indicates approximately when the 45,595,829 shares of our
common stock that are not being sold in the offering but which will be
outstanding at the time the offering is complete will be eligible for sale into
the public market:

</TABLE>

  Most of the restricted shares that will become available for sale in the
public market beginning 180 days after the effective date will be subject to
volume and other resale restrictions pursuant to Rule 144 under the Securities
Act of 1933 because the holders are our affiliates. The general provisions of
Rule 144 are described below.

  In general, under Rule 144, any of our affiliates, or person, or persons
whose shares are aggregated, who has beneficially owned restricted shares for
at least one year, will be entitled to sell in any three-month period a number
of shares that does not exceed the greater of:

  .  1% of the then outstanding shares of the common stock, approximately
     495,958 shares immediately after this offering, or

  .  the average weekly trading volume during the four calendar weeks
     preceding the date on which notice of the sale is filed with the SEC.

In addition, sales pursuant to Rule 144 are subject to requirements relating to
manner of sale, notice and availability of current public information about us.
A person, or persons whose shares are aggregated, who is not deemed to have
been one of our affiliates at any time during the 90 days immediately preceding
the sale and who has beneficially owned his or her shares for at least two
years is entitled to sell such shares pursuant to Rule 144(k) without regard to
the limitations described above.

  As of March 31, 2000, 4,543,905 shares were reserved for issuance under our
1993 stock option plan, of which options to purchase 2,796,198 shares were then
outstanding, all of which were exercisable. We intend to file, within 180 days
after the date of this prospectus, a registration statement under the
Securities Act of 1933 to register the 8,293,905 shares under our 2000 stock
option plan, including the shares from the 1993 stock option plan, and the
600,000 shares of common stock reserved for issuance under our employee stock
purchase plan. Upon registration, all of these shares will be freely tradeable
when issued, subject to Rule 144 volume limitations applicable to affiliates
and lock-up agreements.

Lock-Up Agreements

  Substantially all of the holders of common stock and options to purchase
common stock, including our executive officers and directors and the selling
stockholders, have agreed, pursuant to "lock-up" agreements with Chase
Securities Inc., that they will not offer, sell, contract to sell, pledge,
grant any option to sell, or otherwise dispose of, directly or indirectly, any
shares of common stock or securities convertible or exchangeable for common
stock, or warrants or other rights to purchase common stock for a period of
180 days after the date of this prospectus without the prior written consent of
Chase Securities Inc.. Chase Securities Inc. may release the shares subject to
the lock-up agreements in whole or in part at any time with or without notice.
Currently, Chase Securities Inc. has no plans, however, to do so.

  The underwriting agreement provides that the obligations of the underwriters
are subject to specified conditions precedent, including the absence of any
material adverse change in our business and the receipt of certain
certificates, opinions and letters from us, our counsel and the independent
accountants. The underwriters are committed to purchase all of the shares of
common stock offered by us and the selling stockholders if they purchase any
shares.

  The following table shows the per share and total underwriting discounts and
commissions we will pay to the underwriters. These amounts are shown assuming
both no exercise and full exercise of the underwriters' over-allotment option

</TABLE>

  We estimate that the total expenses of this offering, excluding underwriting
discounts and commissions, will be approximately $1,150,000.

  The underwriters propose to offer the shares of common stock directly to the
public at the initial public offering price set forth on the cover page of this
prospectus and to selected dealers at that price less a concession not in
excess of $0.63 per share. The underwriters may allow and these dealers may
reallow a concession not in excess of $0.10 per share to other dealers. After
the initial public offering of the shares, the offering price and other selling
terms may be changed by the underwriters. The underwriters have informed us
that they do not intend to confirm discretionary sales of more than 5% of the
shares of common stock offered in this offering.

  The selling stockholders have granted to the underwriters an option,
exercisable no later than 30 days after the date of this prospectus, to
purchase up to 600,000 additional shares of common stock at the

                                       63
<PAGE>

initial public offering price, less the underwriting discount set forth on the
cover page of this prospectus. To the extent that the underwriters exercise
this option, each of the underwriters will have a firm commitment to purchase
approximately the same percentage of shares which the number of shares of
common stock to be purchased by it shown in the above table bears to the total
number of shares of common stock offered hereby. The selling stockholders will
be obligated, pursuant to the option, to sell shares to the underwriters to
the extent the option is exercised. The underwriters may exercise this option
only to cover over-allotments made in connection with the sale of shares of
common stock offered hereby.

  The offering of the shares is made for delivery when, as and if accepted by
the underwriters and subject to prior sale and withdrawal, cancellation or
modification of the offering without notice. The underwriters reserve the
right to reject an order for the purchase of shares in whole or in part.

  We and the selling stockholders have each agreed to indemnify the
underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, and to contribute to payments the underwriters may be
required to make in respect of these liabilities.

  Our stockholders, including executive officers, directors and the selling
stockholders, have agreed not to, without the prior written consent of Chase
Securities Inc., offer, sell or otherwise dispose of any shares of common
stock or options to acquire shares of common stock or securities exchangeable
for or convertible into shares of common stock owned by them during the 180-
day period following the date of this prospectus. We have agreed that we will
not, without the prior written consent of Chase Securities Inc., offer, sell
or otherwise dispose of any shares of common stock or options to acquire
shares of common stock or securities exchangeable for or convertible into
shares of common stock during the 180-day period following the date of this
prospectus, except that we may issue shares upon the exercise of options
granted prior to the date hereof. We may grant additional options under our
stock option plans. Without the prior written consent of Chase Securities
Inc., the additional options shall not be exercisable during this 180-day
period.

  The representatives of the underwriters participating in this offering may
over-allot or effect transactions which stabilize, maintain or otherwise
affect the market price of the common stock at levels above those which might
otherwise prevail in the open market, including by entering stabilizing bids,
effecting syndicate covering transactions or imposing penalty bids. A
stabilizing bid means the placing of any bid or the effecting of any purchase,
for the purpose of pegging, fixing or maintaining the price of the common
stock. A syndicate covering transaction means the placing of any bid on behalf
of the underwriting syndicate or the effecting of any purchase to reduce a
short position created in connection with the offering. A penalty bid means an
arrangement that permits the underwriters to reclaim a selling concession from
a syndicate member in connection with the offering when shares of common stock
sold by the syndicate member are purchased in syndicate covering transactions.
Such transactions may be effected on the Nasdaq National Market, in the over-
the-counter market, or otherwise. Stabilizing, if commenced, may be
discontinued at any time.

  Prior to this offering, there has been no public market for the common
stock. The initial public offering price for the common stock has been
determined by negotiation among us and the representatives. Among the factors
considered in determining the initial public offering price were prevailing
market and economic conditions, our revenues and earnings, market valuations
of other companies engaged in activities similar to our business operations
and management.

  You should rely only on the information contained in this prospectus. We
have not authorized anyone to provide you with information different from that
contained in this prospectus. We are offering to sell, and seeking offers to
buy, shares of common stock only in jurisdictions where offers and sales are
permitted. The information contained in this prospectus is accurate only as of
the date of this prospectus, regardless of the time of delivery of this
prospectus or of any sale of our common stock.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors
Sunrise Telecom, Inc.

  We have audited the accompanying consolidated balance sheets of Sunrise
Telecom, Inc. and subsidiaries as of December 31, 1998 and 1999, and the
related consolidated statements of net income, stockholders' equity, and cash
flows for each of the years in the three-year period ended December 31, 1999.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Sunrise
Telecom, Inc. and subsidiaries as of December 31, 1998 and 1999, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1999, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
       (Information as of March 31, 2000 and for the three-month periods
                  ended March 31, 1999 and 2000 is unaudited)

(1) Business and Significant Accounting Policies

 (a) Business

     Sunrise Telecom, Inc. and subsidiaries (the Company) was incorporated in
  California on October 1, 1991. The Company manufactures and markets service
  verification equipment to pre-qualify, verify and diagnose
  telecommunications and Internet networks. The Company markets and
  distributes its products via a worldwide network of manufacturers,
  representatives and independent distributor organizations. The Company has
  wholly owned subsidiaries in Norcross, Georgia; Taipei, Taiwan; a
  representative liaison office in Beijing, China; and a foreign sales
  corporation in Barbados.

 (b) Principles of Consolidation

     The accompanying consolidated financial statements include the accounts
  of the Company and its wholly owned subsidiaries. All significant
  intercompany transactions have been eliminated in consolidation.

 (c) Revenue Recognition

     Revenue is recognized when earned. The Company recognizes revenue from
  product sales upon shipment, assuming collectibility of the resulting
  receivable is probable. Revenue from services and support provided under
  the Company's extended warranty programs is deferred and recognized on a
  straight-line basis over the period of the contract. Deferred revenue
  represents amounts received from customers in respect of the extended
  warranty program in advance of services and support to be provided.
  Provisions are recorded at the time of sale for estimated product returns,
  standard warranty and customer support.

 (d) Warranty Cost

     The Company provides standard warranties covering parts and labor on all
  its hardware products. Estimated warranty costs for such standard
  warranties are charged to cost of sales when the related sales are
  recognized.

 (e) Research and Development

     Development costs incurred in the research and development of new
  products and enhancements to existing products are expensed as incurred
  until the product has been completed, tested, and is ready for commercial
  manufacturing. To date, hardware and software development projects have
  been completed concurrently with the establishment of commercial
  manufacturing and technological feasibility in the form of a working model,
  respectively. Accordingly, no development costs have been capitalized.

 (f) Cash and Cash Equivalents

     The Company considers all highly liquid investments with maturities at
  the date of purchase of three months or less to be cash equivalents. Cash
  equivalents are limited to money market mutual funds.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


 (g) Fair Value of Financial Instruments

     For certain financial instruments, including cash and cash equivalents,
  accounts receivable, accounts payable, notes payable, and accrued expenses,
  recorded amounts approximate fair value due to the relatively short
  maturity period.

 (h) Inventories

     Inventories are stated at the lower of cost or market. Cost is
  determined using the first-in, first-out method.

 (i) Property and Equipment

     Equipment, furniture, fixtures, and leasehold improvements are stated at
  cost. Depreciation and amortization is computed by the straight-line method
  over the shorter of the estimated useful life of the asset or the lease
  term. The estimated useful lives of assets are five years.

     The Company reviews property and equipment for impairment whenever
  events or changes in circumstances indicate that the carrying amount of an
  asset may not be recoverable. Recoverability of property and equipment is
  measured by comparison of its carrying amount to the future net cash flows
  the property and equipment are expected to generate. If such assets are
  considered to be impaired, the impairment to be recognized is measured by
  the amount by which the carrying amount of the property and equipment
  exceeds its fair market value. To date, the Company has made no adjustments
  to the carrying values of its property and equipment.

 (j) Intangible Assets

     Intangibles include the fair value of issued and pending patents,
  technology, noncompete agreements, and goodwill. The Company amortizes such
  intangibles on a straight-line basis over four to five years based on
  expected lives of patents, technology, noncompete agreements, and goodwill.

     The Company reviews intangible assets for impairment based on a
  comparison of the fair value of the intangibles relating to the acquisition
  to their carrying value.

 (k) Income Taxes

     Income taxes are accounted for under the asset and liability method.
  Deferred tax assets and liabilities are recognized for the future tax
  consequences attributable to differences between the financial statement
  carrying amounts of existing assets and liabilities and their respective
  tax bases and operating loss and tax credit carryforwards. Deferred tax
  assets and liabilities are measured using enacted tax rates expected to
  apply to taxable income in the years in which those temporary differences
  are expected to be recovered or settled. The effect on deferred tax assets
  and liabilities of a change in tax rates is recognized in income in the
  period that includes the enactment date.

 (l) Business and Concentrations of Credit Risk

     Financial instruments, which potentially subject the Company to
  concentrations of credit risk, consist primarily of cash equivalents and
  accounts receivable. The Company's cash equivalents are primarily in highly
  liquid money market funds. The Company believes no significant
  concentrations of credit exist with respect to these financial instruments.
  Concentrations of credit risk with respect to trade receivables are limited
  as the majority of the Company's sales are derived from large telephone

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

  operating companies and other telecommunication companies located
  throughout the world. The Company performs ongoing credit evaluations of
  its customers. Based on management's evaluation of potential credit losses,
  the Company believes its allowances for doubtful accounts are adequate. The
  Company had one customer that accounted for 9.9%, 7.7%, 40.6%, 16.5% and
  45.5% of its net sales for the years ended December 31, 1997, 1998 and
  1999, and the three months ended March 31, 1999 and 2000 (unaudited),
  respectively, and $301,000, $148,000, $2,833,000, and $5,265,000 of its
  accounts receivable as of December 31, 1997, 1998 and 1999, and March 31,
  2000 (unaudited), respectively.

     The Company's customers are concentrated in the telecommunications
  industry. Accordingly, the Company's future success depends upon the buying
  patterns of such customers and the continued demand by such customers for
  the Company's products. Additionally, the telecommunications equipment
  market is characterized by rapidly changing technology, evolving industry
  standards, changes in end user requirement, and frequent new product
  introductions and enhancements. Furthermore, the telecommunications
  industry has experienced and is expected to continue to experience
  consolidation. The Company's continued success will depend upon its ability
  to enhance existing products and to develop and introduce, on a timely
  basis, new products and features that keep pace with technological
  developments and emerging industry standards. Furthermore, as a result of
  its international sales, the Company's operations are subject to risks of
  doing business abroad, including but not limited to, fluctuations in the
  value of currency, longer payment cycles, and greater difficulty in
  collecting accounts receivable. While to date these factors have not had an
  adverse material impact on the Company's consolidated results of
  operations, there can be no assurance that there will not be such an impact
  in the future.

 (m) Net Income per Share

     Basic earnings per share (EPS) is computed using the weighted-average
  number of common shares outstanding during the period. Diluted EPS is
  computed using the weighted-average number of common and dilutive common
  equivalent shares outstanding during the period. Dilutive common equivalent
  shares consist of common stock issuable upon exercise of stock options
  using the treasury stock method.

     The following is a reconciliation of the shares used in the computation
  of basic and diluted EPS (in thousands):

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

  Pursuant to Securities and Exchange Commission Staff Accounting Bulletin
  No. 98, convertible preferred stock and common stock granted for nominal
  consideration prior to the anticipated effective date of an initial public
  offering (IPO) must be included in the calculation of basic and diluted net
  income per share as if they had been outstanding for all periods presented.
  To date, the Company has not had any issuances or grants for nominal
  consideration.

 (n) Stock-Based Compensation

     The Company uses the intrinsic-value method in accordance with
  Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock-
  Issued to Employees, to account for employee stock-based compensation.
  Accordingly, compensation cost is recorded on the date of grant to the
  extent the fair value of the underlying share of common stock exceeds the
  exercise price for a stock option or the purchase price for a share of
  common stock. During 1999, the Company issued stock options to employees
  which were subsequently determined to have been issued below the fair value
  of the stock on the date of grant. The compensation cost associated with
  1999 stock options is amortized as a charge against income on a straight-
  line basis over four years vesting period of the options. The Company has
  allocated the amortization of deferred stock-based compensation to the
  departments in which the related employee's services are charged. Pursuant
  to Statement of Financial Accounting Standards (SFAS) No. 123, the Company
  discloses the pro forma effect of using the fair value method of accounting
  for employee stock-based compensation arrangements.

 (o) Use of Estimates

     The preparation of financial statements in accordance with generally
  accepted accounting principles requires management to make estimates and
  assumptions that affect the reporting of assets and liabilities and the
  disclosure of contingent assets and liabilities at the date of the
  financial statements, and the reported amounts of revenues and expenses
  during the period. Accordingly, actual results could differ from those
  estimates.

 (p) Foreign Currency Translation

     The functional currency for the Company's foreign subsidiary located in
  Taiwan is the U.S. dollar. Accordingly, the Company remeasures monetary
  assets and liabilities of this foreign subsidiary at year-end exchange
  rates while nonmonetary items are remeasured at historical rates. Income
  and expense accounts are remeasured at the average rates in effect during
  the year, except for depreciation which is remeasured at historical rates.
  Remeasurement adjustments and transaction gains and losses are recognized
  in income in the year of occurrence.

     The functional currency for the Company's foreign subsidiary located in
  Italy is the local currency. Accordingly, the Company applies the current
  exchange rate to translate the subsidiary's assets and liabilities and the
  weighted average exchange rate to translate the subsidiary's revenues,
  expenses, gains and losses into U.S. dollars. Translation adjustments are
  included as a separate component of comprehensive income within
  stockholders' equity in the accompanying consolidated financial statements.

 (q) Other Comprehensive Income

     Comprehensive income comprises net income and other comprehensive
  income. Other comprehensive income includes certain changes in equity of
  the Company that are excluded from net income, including foreign currency
  translation adjustments.

 (r) Advertising Expense

     The cost of advertising is expensed as incurred. Such costs are included
  in selling and marketing expense and totaled approximately $743,000,
  $848,000, and $1,023,000 during the years ended December 31, 1997, 1998,
  and 1999, respectively, and approximately $263,000 and $341,000 for the
  three months ended March 31, 1999 and 2000 (unaudited).

 (s) Recent Accounting Pronouncement

     In June 1998, the Financial Accounting Standards Board (FASB) issued
  SFAS No. 133, Accounting for Derivative Interments and Hedging Activities.
  SFAS No. 133 establishes accounting and reporting standards, requiring that
  every derivative instrument be recorded in the balance sheet as either an
  asset or liability measured at its fair value. SFAS No. 133, as recently
  amended, is effective for fiscal years beginning after June 30, 2000.
  Management believes the adoption of SFAS No. 133 will not have a material
  effect on the Company's financial position or results of operations.

 (t)Unaudited Balances

     The accompanying unaudited financial statements for the three months
  ended March 31, 1999 and 2000 include all adjustments (consisting of only
  normal recurring adjustments) that management considers necessary for a
  fair presentation of the financial position and results of operations as of
  the date and for the periods indicated.

(2) Related Party Transactions

  One of the significant stockholders of the Company is also the owner of
Telecom Research Center. During 1997, 1998, and 1999, the Company purchased
equipment used in its manufacturing process totaling $81,000, $84,000, and
$58,000, respectively, from Telecom Research Center. As of December 31, 1997,
1998, and 1999, there were no accounts payable due to Telecom Research Center.
The terms of these transactions were similar to those of unrelated parties.

  During 1999, the Company issued an employee a promissory note in an aggregate
principal amount of $50,000. The note bears interest at 7.75% per annum and is
payable monthly with the final payment due in December 2004. As of December 31,
1999, the outstanding balance totaled $44,034.

(5) Minority Investment

  During 1998 the Company acquired 1,666,667 shares (approximately 16.4%) of
the common stock of Top Union Electronics (Top Union), a Taiwan R.O.C.
corporation, for a purchase price of $606,612. Top Union is a subcontractor
manufacturer utilized by the Company for the manufacture of certain products.
During 1999, the Company invested an additional $39,000 in Top Union as part of
one of two external rounds of third-party financing obtained by Top Union. This
investment by the Company was less than 16.4% of the total financing raised by
Top Union and, thus, diluted the Company's ownership of Top Union to 14.6%. The
Company accounts for this investment using the cost method of accounting.
During the years ended December 31, 1998 and 1999, the Company purchased
$26,406 and $94,227, respectively, in product from Top Union. As of December
31, 1998 and 1999, the Company had $0 and $36,484, respectively, in

accounts payable to Top Union. The Company evaluates the fair value of its
investment based on the valuation associated with third party external rounds
of financing. To date no impairment charges have been recognized.

(6) Other Assets and Commitments

  Other assets as of December 31, 1999 and March 31, 2000 (unaudited) consisted
principally of a $2,675,000 deposit for the Company's new facility, currently
under construction, which is estimated to be completed in late 2000. The total
cost of the new facility is estimated to be $17,000,000.

(7) Notes Payable and Line of Credit

  In connection with the acquisition of Hukk Engineering ("Hukk"), the Company
issued two notes payable, a $450,000 note related to a noncompete agreement due
in quarterly installments of $28,125 through October 2004, and a $450,000 note
due in quarterly installments through October 2004 bearing interest at a rate
of prime plus 2.5%.

  In connection with the acquisition of Pro.Tel, the Company issued a $500,000
note related to a non-compete agreement due in quarterly installments of
$31,250 through March 2004. The Company also issued a $100,000 note payable,
related to the Pro.Tel USA acquisition, which is due in May 2000.

  The remaining borrowings consisted of borrowings from various Italian
financial institutions, which bear interest at variable rates, ranging from
6.0% to 6.75% at March 31, 2000, based on the ABI prime rate. At March 31,
2000, $77,000 (unaudited) had been drawn down under these facilities.
Generally, these foreign credit lines do not require commitment fees or
compensating balances and are cancelable at the option of the Company or the
financial institutions.

  The Company has a $3,000,000 revolving line of credit with a financial
institution that expires on October 1, 2000, bearing interest at the bank's
prime rate (8.5% as of December 31, 1999). The agreement, which is
collateralized by the receivables and inventories of the Company, contains
certain financial covenants and restrictions. As of December 31, 1998 and 1999
and March 31, 2000 (unaudited), there were no balances outstanding under the
line of credit.

(8) Leases

  The Company leases its facilities under operating lease agreements, expiring
January 2001 and August 2004. The leases require the Company to pay property
taxes and normal maintenance. Future minimum lease payments, under these
agreements, as of December 31, 1999, are as follows (in thousands):

its new facility.

(9) Capital Stock

 Common Stock

  In January 1997, the Company's Board of Directors approved the increase of
the authorized common stock to 100,000,000 shares and approved a five-for-one
stock split of its common stock. All share amounts in the accompanying
consolidated financial statements have been retroactively adjusted to reflect
the stock split.

  The Company established a program of repurchasing common stock in order to
offer liquidity to its stockholders. Repurchases are offered based on
valuations performed by the Company of the fair value of its stock at the time
of repurchase. During 1997, 1998, and 1999, the Company repurchased
approximately 298,000, 135,000, and 135,000 shares of common stock,
respectively, for $325,000, $195,000, and $202,000, respectively.

 Stock Issued in Acquisition Subject to Put Agreement

  On February 22, 2000, the Company issued 500,001 shares of its common stock
to the former Pro.Tel shareholders as part of the total purchase price for
Pro.Tel (see Note 11. Acquisitions) and granted those shareholders the right to
"put" their shares back to the Company for cash at $10.00 per share on May 22,
2000. If all of the former Pro.Tel shareholders elect to sell their shares back
to the Company, it will be required to pay them $5.0 million in cash.

(10) Stock Option Plan

  Under the terms of the 1993 Employee Stock Option Plan (the Option Plan), the
Company's Board of Directors may grant options to directors, officers, and
employees of the Company to purchase not more than an aggregate of 5,250,000
shares of the Company's common stock.

  Options may be granted as incentive stock options or nonstatutory stock
options at the fair market value of such shares on the date of grant as
determined by the Board of Directors. Options granted prior to 1996 expire 5
years from the date of grant and are exercisable in 3 equal annual installments
commencing 1 year from the date of grant. Upon termination of employment, the
optionee may exercise any such vested options within 30 days of termination.
Options granted subsequent to 1996 vest over a 4-year period, and expire at the
end of 10 years from the date of grant, or sooner, if terminated by the Board
of Directors.

  The options include a provision whereby the option holder may elect at any
time to exercise the option prior to the full vesting of the option. Unvested
shares so purchased are subject to a repurchase right by the Company at the
original purchase price. Such right shall lapse at a rate equivalent to the
vesting period of the original option. As of December 31, 1997, 1998, 1999 and
March 31, 2000 (unaudited), shares issued and subject to repurchase were 9,000,
6,750, 25,161 and 80,025, respectively.

  The Company uses the intrinsic-value based method to account for its
employees stock-based compensation plan. For options granted in 1997 and 1998,
no compensation cost has been recognized in the accompanying consolidated
financial statements for options granted under this plan as the exercise price
of each option equaled or exceeded the fair value of the underlying common
stock as of the grant date. With respect to options granted in 1999, the
Company has recorded unearned stock-based compensation of approximately
$2,270,000 for the difference at the grant date between the exercise price and
the fair value.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


  The deferred compensation represents the aggregate difference, at the date of
grant, between the respective exercise price of stock options and the estimated
fair value of the underlying common stock. The total unearned stock-based
compensation recorded for all option grants through December 31, 1999, will be
amortized as follows for the years ending December 31: 2000, $567,000; 2001,
$567,000; 2002, $567,000; and 2003, $364,000. The amount of deferred stock
compensation expense to be recorded in future periods could decrease if options
for which accrued but unvested compensation has been recorded are forfeited.

  If compensation for the Company's stock-based compensation plans had been
determined in a manner consistent with the fair value approach described in
SFAS No. 123, Accounting for Stock-Based Compensation, the Company's net income
and net income per share, as reported, would have been reduced to the pro forma
amounts indicated below (in thousands, except per share data):

  The provisions of SFAS No. 123 are effective for options granted beginning
January 1, 1996. Options vest over several years and new options are generally
granted each year. Because of these factors, the pro forma effect shown above
may not be representative of the pro forma effect of SFAS No. 123 in future
years.

  For the purposes of computing pro forma net income, the fair value of each
option grant is estimated on the date of grant using the Black-Scholes option
pricing model. The assumptions used to value the option grant are as follows:

   Intangibles include the fair value of technology and noncompete agreements
with resulting excess purchase price allocated to goodwill. The Company
amortizes such intangibles on a straight-line basis over four to five years
based on expected lives of technologies, noncompete agreements, and goodwill.
If the identified technologies are not successfully developed, the Company may
not utilize the value assigned to intangible assets.

  Pro.Tel

  On February 22, 2000, the Company acquired all the outstanding shares of
Pro.Tel. Srl and subsidiaries, an Italian manufacturer of distributed network
signal analysis equipment. The Company paid $4,100,000 in cash and acquisition
costs, a note payable related to a non-compete agreement for $500,000, payable
over four years, and 500,001 contingently issuable shares of the Company's
stock valued at $5,000,000. The 500,001 shares of stock in Sunrise were granted
to the former Pro.Tel shareholders with the right to "put" their Sunrise stock
to the Company for cash on May 22, 2000 for $10.00 per share. The "put" feature
represents, in effect, a guarantee of purchase price, which was used in
conjunction with both a discounted cashflow and market-based valuations in
determining the valuation of the shares issued in connection with the
acquisition.

  The transaction has been accounted for under the purchase method. The results
of Pro.Tel and the estimated fair value of assets acquired and liabilities
assumed are included in the Company's financial statements from the date of

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


  In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
assets will be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the periods in
which those temporary differences become deductible. Based on the level of
historical taxable income and projections for future taxable income over the
periods which the deferred tax assets are deductible, management believes it is
more likely than not that the Company will realize the benefits of such
deferred assets.

(14) Segment Information

  SFAS No. 131, Disclosure About Segments of an Enterprise and Related
Information, establishes standards for the manner in which public companies
report information about operating segments, products, services, geographic
areas, and major customers in annual and interim financial statements. The
method of determining what information to report is based on the way that
management organizes the operating segments within the enterprise for making
operating decisions and assessing financial performance.

  The Company's chief operating decision-maker is considered to be the
Company's Chief Executive Officer (CEO). The CEO reviews financial information
presented on a consolidated basis accompanied by disaggregated information
about revenue by geographic region for purposes of making operating decisions
and assessing financial performance. The consolidated financial information
reviewed by the CEO is the same as the information presented in the
accompanying consolidated statements of operations. In addition, as the
Company's assets are primarily located in its corporate offices in the United
States and not allocated to any specific segment, the Company does not produce
reports for or measures the performance of its segments based on any asset-
based metrics. Therefore, the Company operates in a single operating segment
the design, manufacture, and sale of digital test equipment for
telecommunications, transmission, and signaling applications.

  Revenue information regarding operations in the different geographic regions

                     SUNRISE TELECOM, INC. AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


(15) Subsequent Events

 (a) Recapitalization

   On March 7, 2000, the Board of Directors authorized the filing of a
   registration statement with the SEC that would permit the Company to sell
   shares of the Company's common stock in connection with a proposed
   initial public offering. On April 5, 2000, the Company's Board of
   Directors approved the reincorporation of the Company into Delaware
   effecting the authorization of 175,000,000 shares of $0.001 par value per
   share common stock and 10,000,000 shares of $0.001 par value preferred
   stock. The Company's stockholders approved the reincorporation on April
   22, 2000. The reincorporation will be effective upon the Company's
   initial public offering. The Board of Directors also authorized a three-
   for-one stock split of its common stock and the change of the name of the
   company to Sunrise Telecom Incorporated. The consolidated financial
   statements have been adjusted to give effect to the recapitalization.

 (b) 2000 Employee Stock Purchase Plan

   In April 2000, the Company's Board of Directors approved the adoption of
   the 2000 Employee Stock Purchase Plan (the "Purchase Plan") and reserved
   600,000 shares of common stock for issuance thereunder. The Purchase Plan
   will be effective upon the Company's initial public offering. The
   Purchase Plan permits eligible employees to purchase common stock through
   payroll deductions of up to 15% of the employee's total base
   compensation, not to exceed $25,000 in any plan year, excluding bonuses,
   commissions and overtime at a price equal to 85% of the lower of the fair
   market value of the common stock on the first day of the offering period
   or on the last day of the purchase period.

 (c) 2000 Stock Plan

   In April 2000, the Company's Board of Directors approved the adoption of
   the 2000 Stock Plan (the "Stock Plan.") The Stock Plan will become
   effective upon the Company's initial public offering. The total number of
   shares reserved for issuance under the stock plan equals 3,750,000 shares
   of common stock plus the number of shares that remain reserved for
   issuance under the 1993 stock option plan as of the date the stock plan
   becomes effective. All outstanding options under the 1993 stock option
   plan will be administered under the 2000 Stock Plan but will continue to
   be governed by their existing terms.

 (d) Line of Credit

   In April 2000, the Company increased their available line of credit from
   $3 million to $9 million. The line of credit now expires on May 1, 2001
   and continues to be collateralized by the receivables and inventories of
   the Company.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and
Quotaholders of Pro.Tel. Srl

  We have audited the accompanying consolidated balance sheets of Pro.Tel. Srl
and its subsidiary as of December 31, 1998 and 1999 and the related
consolidated statements of operations, quotaholders' equity and cash flows for
each of the years in the two-year period ended December 31, 1999. These
financial statements are the responsibility of the management of Pro.Tel. Srl.
Our responsibility is to express an opinion on these financial statements based
on our audits.

  We conducted our audits in accordance with auditing standards generally
accepted in the Republic of Italy, which standards are substantially similar in
all material respects to generally accepted auditing standards in the United
States of America. Those standards require that we plan and perform the audits
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Pro.Tel.
Srl and its subsidiary as of December 31, 1998 and 1999, and the results of
their operations and their cash flows for each of the years in the two-year
period ended December 31, 1999 in conformity with accounting principles
generally accepted in the Republic of Italy.

  Accounting principles established or adopted by Italian law and the Italian
Accounting Profession, as described in note 1, vary in certain significant
respects from generally accepted accounting principles in the United States of
America. Application of generally accepted accounting principles in the United
States of America would have affected the results of operations for each of the
years in the two-year period ended December 31, 1999 and quotaholders' equity
as of December 31, 1998 and 1999 to the extent summarized in note 26 to the
consolidated financial statements.

1. Organization and summary of significant accounting policies

  Pro.Tel. Srl (hereafter "Pro.Tel.' or the "Company') was incorporated on July
24, 1996 with a quota capital of L100,000 thousand and is registered in Italy
with limited liability and is regulated by Italian law.

  On June 25, 1998 Pro.Tel. purchased 100% of the quota capital of Tel.Mark.
Srl (hereafter "Tel.Mark.') from certain quotaholders of Pro.Tel.. Tel.Mark. is
registered in Italy with limited liability and is regulated by Italian law.

  The Extraordinary General Meeting of the quotaholders on June 25, 1998
increased the quota capital of the Company from L100,000 thousand to L500,000
thousand.

  Pro.Tel. is a full service telecommunication engineering consulting and
manufacturing company and provides hardware, firmware and software design. In
particular Pro.Tel. is a worldwide company designing both test and network
equipment for the data and telecommunications industry and prototyping products
for the Information Communication market. The volume of sales became
significant at the end of 1998.

  Tel.Mark. supplies administrative services, office space, technical
assistance and specific advice concerning data and telecommunication networks
primarily to Pro.Tel. The annual remuneration for these activities provided to
Pro.Tel. is L360 million for the period from October 1, 1999 to October 1,
2000.

  The offices and the production site of Pro.Tel. and its subsidiary (hereafter
the "Group') are located in Vaciglio Modena, Italy.

  The By-laws of Pro.Tel. and Tel.Mark. contain specific clauses restricting
the transfer or sale of the companies' quota to third parties. In the event of
such a sale or transfer, the existing quotaholders have the right of first
refusal. Otherwise, such a transaction would be subject to the approval of the
majority of the existing quotaholders.

  A summary of the significant accounting policies followed by the Group is set
out below:

  Principles of preparation and consolidation

  The consolidated financial statements of the Company have been prepared for
distribution to its quotaholders in conformity with accounting standards issued
by the "Consigli Nazionali dei Dottori Commercialisti e dei Ragionieri'
(National Boards of Public Accountants in Italy) which include those
established or adopted by the Italian Civil Code, and where these are not
exhaustive, with standards issued by the International Accounting Standard
Committee (I.A.S.C.). Hereafter these have been identified as "Italian GAAP'.
Italian GAAP differ in certain respects from generally accepted accounting
principles in the United States of America ("US GAAP'). A description of these
differences and their effects on net profit/(loss) and quotaholders' equity is
set forth in note 26. The consolidated financial statements have been
reformatted from the original Italian statutory financial statement
presentation to conform more closely with international presentation and
include certain additional disclosures required by the US Securities and
Exchange Commission ("the SEC').

  The consolidated financial statements for the years ended December 31, 1998
and 1999, have been prepared on the basis of statutory accounts of Pro.Tel. Srl
and its subsidiary Tel.Mark. Srl. The statutory accounts of the two companies
for the year ended December 31, 1999 have not yet been approved by the Board of
Directors and the Quotaholders' Meeting. The consolidated financial statements
for the years ended December 31, 1998 and 1999 have been approved by the Board
of Directors during the meeting held on February 17, 2000.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


  All significant intercompany balances and transactions have been eliminated
in consolidation.

  As noted above, the company acquired 100% of the quota capital of Tel.Mark.
on June 25, 1998 for L60 million. The majority of the quotaholders of Tel.Mark.
were also quotaholders of Pro.Tel. as of January 1, 1998 and the date of
acquisition. Therefore, for purposes of these consolidated financial
statements, the financial position and results of operations of Tel.Mark. prior
to the acquisition date have been combined with Pro.Tel. as of January 1, 1998,
the earliest period presented. No goodwill was recorded as a result of this
transaction.

  Cash and bank borrowings

  Cash and bank borrowings are stated at nominal value and include accrued
interest.

  Accounts receivable and payable

  Receivables are stated at nominal value net of an allowance for doubtful
accounts. Payables are stated at face value.

  Inventories

  Inventories are stated at the lower of cost or net realizable value. The cost
is determined using the average purchase cost method.

  Plant and equipment

  Plant and equipment are stated at cost less accumulated depreciation.
Maintenance and repairs are expensed as incurred; significant improvements are
capitalized and depreciated over the useful lives of the related assets.

  Depreciation is calculated on the straight-line method over the estimated
useful lives of the assets. The following table summarizes the annual
depreciation rates of the Group's plant and equipment:

<TABLE>

                                                                         Annual
                                                                          rate
                                                                         ------
     <S>                                                                 <C>
     Plant and machinery................................................ 12-30%
     Industrial and sales tooling/equipment............................. 15-30%
     Other.............................................................. 10-25%
</TABLE>

  Assets acquired during the year are depreciated at half the annual rate in
order to take into account the average period of utilization thereof.

  Assets acquired with a unit cost less than L1 million are charged to the
profit and loss account given their limited estimated useful life.

  Assets acquired under capital leases are treated in the same manner as
operating leases, with the purchase of the asset being recorded at the price
paid to acquire title at the end of the lease term.

  Intangible assets

  Intangible assets are carried at the purchase price and are amortized on the
straight-line method over the estimated useful lives of the assets. The
following table summarizes the estimated useful lives of the Group's intangible
assets:

<TABLE>
<CAPTION>
                                                                          Years
                                                                          -----
     <S>                                                                  <C>
     Incorporation and expansion costs...................................    5
     Research and development costs on specific development projects.....    5
     Software............................................................    5
</TABLE>

  In addition to the above, intangible assets include leasehold improvements
which are amortized on a straight-line basis over the shorter of the lease term
or estimated life of the asset.

  Research and development costs, comprising principally external consultants
employed in that activity, are capitalized as an intangible asset for specific
development projects. The amortization is allocated to cost of goods sold' and
selling, general and administrative expenses' based on their useful life. The
total amount capitalized was L51,506 thousand all of which related to expenses
incurred prior to December 31, 1997. No such costs have been incurred or
capitalized in the years ended December 31, 1998 and 1999 as there have been no
specific development projects that could be capitalized in conformity with
accounting principles generally accepted in the Republic of Italy. All research
and development costs have been expensed as incurred in 1998 and 1999.

  Management periodically assesses the recoverability of intangible assets and,
in cases where such an asset is deemed to have no remaining useful economic
life, the carrying value of the asset is written off in full.

  Advertising costs

  Advertising costs are expensed as incurred.

  Income taxes

  Current income tax payable by each of the two individual companies included
in the consolidation is calculated according to the tax regulations in force in
Italy and is classified net of the advances paid or withholdings sustained
under "income and other taxes payable'. If the net amount is a debit balance,
it is classified under "other current assets'. In addition, a provision is made
for deferred tax liabilities of the two individual companies, as well as those
deriving from consolidation adjustments, net of deferred tax assets, if any,
where realization of the benefit is considered reasonably certain on the basis
of the Group's forecasted performance.

  Deferred income taxes are calculated at the relevant tax rates in force in
Italy at the balance sheet date and are reviewed annually to reflect changes in
the economic circumstances of the companies and in the tax rates.

  Revenue and cost recognition

  Revenues are recognized when title passes to the customer, usually the date
of shipment or when services are rendered to the independent dealer or other
third party. Costs are recognized on the accrual basis.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


  Employee benefit plans

  Leaving entitlements reflect the liability to employees when they leave their
employment, calculated in conformity with current Italian legislation, and are
based on a percentage of remuneration. The full amount of the employees' vested
benefits is accrued. The liability is adjusted annually by 1.5% plus 75% of the
official inflation. There is no funding requirement associated with this
liability. Employees' leaving entitlements charged in the years ended December
31, 1998 and 1999 amounted to L37,285 thousand and L53,236 thousand,
respectively.

  Foreign currencies

  Foreign currency transactions are recorded at the exchange rates applicable
at the transaction dates. Assets and liabilities denominated in foreign
currencies are re-measured at exchange rates applicable at the balance sheet
date unless covered by a hedge instrument. Balances denominated in currencies
of the member countries of the European Monetary Union at December 31, 1998 and
1999 have been recorded at their final Euro conversion rates with respect to
the Italian Lire. The resulting gains and losses on assets and liabilities are
recorded in the consolidated statement of operations.

  Grants

  Grants received for reimbursement of research and development expenses not
capitalized are recorded as non operating income when they become receivable.
Grants are considered receivable when the Company's request is approved by the
governmental institution. The related expenses are recorded in the financial
year when incurred.

  Use of estimates

  Management has made a number of estimates and assumptions relating to the
reporting of assets and liabilities and the disclosure of contingent assets and
liabilities to prepare these financial statements in conformity with generally
accepted accounting principles in the Republic of Italy and, with respect to
note 26, the United States of America. Actual results could differ from those
estimates.

2. Translations of Italian Lire into US Dollars

  The consolidated financial statements are stated in Italian Lire. The
translations of Italian Lire into US Dollars are included solely for the
convenience of the reader, using the noon buying rate in New York on December
31, 1999, which was 1,922.810327 to $1.00. The convenience translations are
unaudited and should not be construed as representations that the Italian Lire
amounts have been, could have been, or could in the future be, converted into
US Dollars at this or any other rate of exchange.

</TABLE>

  Trade receivables denominated in US Dollars totalled 644,231 US Dollars and
51,727 US Dollars at December 31, 1998 and 1999, respectively.

  The Group is potentially subject to concentrations of credit risk principally
on its accounts receivable balances. Management believes, however, that the
loss due to credit risk to be incurred by the Group if parties to these
receivables failed completely to perform according to the terms of the
contracts is not material. The Group does not require collateral and all the
accounts receivable balances are unsecured. While management believes the trade
receivables will ultimately be collected, it anticipates that in the event of
default they will follow normal collection procedures. The Group estimates the
allowance for doubtful accounts on the basis of the credit worthiness of its
customers as well as general economic conditions. Consequently, an adverse
change in those factors could affect estimates of bad debts. As described in
note 17, Pro.Tel.'s products are sold exclusively by independent distributors
pursuant to a distribution agreement with the Company. During the years ended
December 31, 1998 and 1999, two customers/distributors (Pro.Tel. USA in 1998
and 1999; Chevas in 1998; Set-up in 1999) accounted for approximately 89% and
63%, respectively, of net sales for products of the Group. In addition, these
customers, who are unrelated third parties, accounted for 74% and 88%,
respectively, of the trade receivable balance as of December 31, 1998 and 1999.

  Sales made to distributors (which are all unrelated third parties) are
recognized on the date of shipment of the goods and are not subject to any
rights of return other than for defects in materials or workmanship, as
described in Note 17. Furthermore, these sales are not contingent upon their
subsequent sale to third parties by the distributors.

non-income taxes due and withholdings of tax yet to be reimbursed at the
balance sheet date, net of the advances paid or withholdings sustained.

the Italian law 140/97 (see note 22). The Italian fiscal authority permits the
taxation of such amounts to be deferred for a period of five years. Deferred
taxes are calculated at the effective IRPEG tax rate of the company at December
31, 1999 (27%) and are classified between short-term and long-term.

  At December 31, 1998 the Group had one forward foreign exchange contract
outstanding for 28,000 US Dollars which was designated as being for hedging
purposes. The Group uses these contracts to manage its exposure to foreign
currency fluctuations.

  There were no other foreign exchange contracts, futures, options or other
financial instruments open at December 31, 1998 and 1999.

  The Group is subject to the national agreement for "mechanical engineering
employees' which covers all of its employees. The contract expires in 2001.
Management expects that this agreement will be renewed without any significant
adverse effects to the operations of the Group.

  The Group is not involved in any claims or legal actions arising in the
ordinary course of its business.

17. Net sales

  The Group operates predominantly in a single industry segment:
telecommunication engineering consulting and manufacturing market, by providing
hardware, firmware and software design. The Group offers a wide product range
of items for sale, manufactured and marketed.

  The Group also produces personalized products upon the order of customers.

  Warranties are given by the group for labor and material costs for a period
of 14 months from the date of sale. Due to the nature, high quality and
workmanship of Pro. Tel's products, managements does not expect warranty costs
to be significant. For the years ended December 31, 1999 and 1998, the group
incurred insignificant product warranty costs. Therefore, management does not
consider any additional provision to be required as at December 31, 1999 and
1998.

  Pro.Tel.'s products are sold exclusively by distributors in Italy, China,
Switzerland, France, Germany, USA, Austria, UK, Japan, Korea and Malaysia.

  During 1999, the Company applied for reimbursement of certain research and
development expenditures from the Ministry of Industry and Trade under the
Italian law 140/97.

  This application was subsequently approved by the Ministry of Industry and
Trade at which time the Company recorded grant revenue of L217,706 thousand.
The research and development costs were incurred in the year ended December 31,
1998 and related primarily to personnel costs. The grant is recovered through
reductions of the Company's employer withholding taxes and the remaining amount
to be received was L20,942 thousand as of December 31, 1999.

23. Income taxes

  The two consolidated Group companies are located in Italy; consequently the
Group's activities are only affected by the income tax regime in Italy. Income
taxes recorded in the consolidated financial statements are IRPEG (national
corporate income tax) and IRAP (regional corporate income tax). IRPEG is
calculated at 37% of taxable income, but a reduced rate can be applied in
certain circumstances, in the presence of an increase of net equity of the
company, applying DIT (dual income tax) regulation. IRAP is levied at 4.25% on
certain components of revenue and expenses, which broadly speaking are all
business revenues less costs for purchases of materials and services and
depreciation and amortization excluding all other production, administration
and selling costs (such as personnel costs and charge for doubtful accounts).
Because of the method of calculation, IRAP is not directly related to pre-tax
income.

  Deferred income taxes have been determined on the basis of the effective 1999
tax rate (see note 13).

  Income tax charge is composed of the following:

25. Subsequent events

  At the beginning of year 2000 the terms of an agreement between the
quotaholders of Pro.Tel. and Sunrise Telecom Inc, a company incorporated in the
United States of America, regarding the sale of 100% of the quota capital of
the Company, has been defined but has not yet been signed by the respective
parties. The transaction will be finalized in the first quarter of year 2000
and represents the best opportunity for development and growth for Pro.Tel.

26. Summary of significant differences between generally accepted accounting
principles in the Republic of Italy and the United States of America

  The accompanying consolidated financial statements of the Company have been
prepared in conformity with accounting principles established or adopted by
Italian law and the Italian Accounting Profession, as described in note 1
("Italian GAAP'). Those standards differ in certain significant respects from
those generally accepted in the United States ("US GAAP'). Set forth below is a
summary of certain significant differences between Italian and US GAAP which
management believe are relevant to the Group.

(a)  Intangible assets

     Under Italian GAAP certain costs, principally research and development
  expenditures on specific product development projects and incorporation and
  expansion costs, are deferred and amortized over the estimated useful lives
  of the respective assets. There were no significant increases in intangible
  assets for these items under Italian GAAP in 1998 and 1999. Under US GAAP,
  such costs are expensed as incurred.

(b) Leasing

     Under Italian GAAP, all leases are accounted for as an operating lease,
  i.e., plant and equipment acquired under capital leases are not recognized
  as equipment along with the obligation under capital lease until the end of
  the lease term. Under US GAAP, where the necessary conditions are met, the
  plant and equipment are recorded at the present value of minimum lease
  payments and the obligation under capital leases is recognized as a
  liability. The related assets are then amortized over their useful economic
  lives. In certain circumstances, Pro.Tel. has made payments in advance of
  delivery of leased assets. Under Italian GAAP, these advance payments are
  recognized as an expense in the period in which they are paid and are
  recorded in costs of goods sold. Under US GAAP, such advance payments would
  be accounted for as a prepaid expense.

(c) Balance sheet reclassification differences

     Under Italian GAAP leasehold improvements and purchased software costs
  are classified as "other intangible assets' whereas these items would be
  classified under "plant and equipment' for US GAAP purposes.

(d) Statement of cash flows

     With regard to the consolidated statements of cash flows, differences in
  classifications with that presented under Italian GAAP arise not only from
  the aforementioned differences in presentation and principle in the
  consolidated balance sheet but also from the fact that under US GAAP, the
  effect of exchange rate changes on cash are included as a separate line
  item of the consolidated statements of cash flows rather than within
  operating activities.

Income taxes--US GAAP basis

  As described in note 23, the two consolidated companies are both located in
Italy. Consequently the profit before income taxes and the income tax expenses
consists only of domestic items which arise from the ordinary operating
activities of the Group.

  Income taxes differ from the amounts computed by applying the Italian
statutory income tax rate (37%) to pre-tax income as a result of the following:

 Leasing--US GAAP basis

  On October 2, 1998 Pro.Tel. signed a leasing contract relating to personal
computers that expires in 2001. Since such machinery was delivered on January
28, 1999, they have been included (together with the related obligations) in
the US GAAP reconciliation starting from 1999. At December 31, 1999, the gross
amount capitalized and related accumulated amortization of this lease amounted
to L27,560 thousand and L2,756 thousand, respectively. Plant and equipment,
net, and the related obligations would be higher by L24,804 thousand and
L17,549 thousand, respectively, as of December 31, 1999.

  Future minimum capital lease payments as of December 31, 1999 are:
