                                  COMMON STOCK

          The 159,997 shares (the "Shares") of Common Stock of Ascend
Communications, Inc., a Delaware corporation ("Ascend" or the "Company") offered
by this Prospectus were issued in connection with the merger of Ascend
Acquisition Corporation, a Delaware corporation and a wholly-owned subsidiary of
Ascend ("Sub") with and into StonyBrook Services Inc., a New York corporation
("StonyBrook"), which was consummated on December 27, 1996 (the "StonyBrook

effective registration statement.  The Company will not receive any of the
proceeds from the sale of the Shares by the Selling Stockholders.  See "Use of
Proceeds."

  The Company has been advised by the Selling Stockholders that they intend to
sell all or a portion of the Shares from time to time in The Nasdaq National
Market, in negotiated transactions or otherwise, and on terms and at prices then
obtainable.  The Selling Stockholders and any broker-dealers, agents or
underwriters that participate with the Selling Stockholders in the distribution
of any of the Shares may be deemed to be "underwriters" within the meaning of
the Securities Act, and any commission received by them and any profit on the
resale of the Shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act.  The Company has agreed to
indemnify in certain circumstances the Selling Stockholders against certain
liabilities, including liabilities under the Securities Act.  The Selling
Stockholders have agreed to indemnify in certain circumstances the Company
against certain liabilities, including liabilities under the Securities Act.
See "Plan of Distribution."

  The Company will bear all out-of-pocket expenses incurred in connection with
the registration of the Shares, including, without limitation, all registration
and filing fees imposed by the Securities and Exchange Commission (the
"Commission"), the National Association of Securities Dealers ("NASD") and blue
sky laws, printing expenses, transfer agents' and registrars' fees, and the
reasonable fees and disbursements of the Company's outside counsel and
independent accountants and a single counsel for all of the Selling
Stockholders, but excluding underwriting discounts and commissions and transfer
or other taxes and other costs and expenses incident to the offering and sale of
the shares to the public which shall be borne by the Selling Stockholders.

  THE SHARES HAVE NOT BEEN REGISTERED FOR SALE UNDER THE SECURITIES LAWS OF ANY
STATE OR JURISDICTION AS OF THE DATE OF THIS PROSPECTUS.  BROKERS OR DEALERS

                                  THE COMPANY

     Ascend develops, manufactures, markets, sells and supports a broad range of
high-speed digital remote networking access products that enable its customers
to build:  (i) Internet access systems consisting of point of presence ("POP")
termination equipment for Internet Service Providers ("ISPs") and remote site
Internet access equipment for Internet subscribers; (ii) extensions and
enhancements to corporate backbone networks that facilitate access to these
networks by remote offices, telecommuters and mobile computer users; and (iii)
videoconferencing and multimedia access facilities.  These products are termed
bandwidth on demand systems because they establish high-speed switched digital
connections whose bandwidth, duration and destination can be adjusted to suit
user application needs.  These products support existing digital and analog
networks.

     Ascend has three bandwidth on demand remote networking access product
families, each of which is focused on major application segments: MAX products
for wide area network ("WAN") access to corporate backbone networks, Internet
access in POPs and multimedia access facilities; Pipeline products for
telecommuting, remote office access and Internet access by individual sites or
users and Multiband products for videoconferencing and multimedia networks.
These products support a wide variety of application interfaces, switched
digital services, digital modem services and digital and analog access line
types. In addition, Ascend has recently introduced its GRF products family for
high speed IP switching on backbone networks. This wide range of connectivity
and interoperability options significantly increases the number of POP,
corporate and individual sites that can benefit from these products. Ascend's
products are distributed and serviced globally and Ascend maintains marketing
and sales relationships with ISPs, including UUNET, PSI, BBN, MCI, EUNET, Demon,
Pipex and NTT-PC, with major telecommunications carriers, including AT&T,
Sprint, MCI, GTE, Pacific Bell, Southwestern Bell, British Telecom, France
Telecom, Deutsche Telekom and NTT in Japan, with video equipment providers,
including Compression Labs, GPT, PictureTel and VTEL, and with value-added
resellers ("VARs") and distributors.

     On December 27, 1996, Ascend completed the StonyBrook Merger.  As a result
of the StonyBrook Merger, StonyBrook became a wholly-owned subsidiary of the
Company. The Merger was treated as a pooling of interests for accounting and
financial reporting purposes. Upon consummation of the StonyBrook Merger, the
Company issued approximately 290,490 shares of its Common Stock (29,049 of which
are subject to an escrow) and assumed outstanding options which in January 1997
were exercised for an additional 189,501 shares of Ascend Common Stock (18,950
of which are subject to an escrow).

     The principal executive offices of Ascend are located at One Ascend Plaza,
1701 Harbor Bay Parkway, Alameda, California 94502 and its telephone number at
that location is (510) 769-6001.

                                  RISK FACTORS

     The following risk factors should be considered in conjunction with the
other information included and incorporated by reference in this Prospectus
before purchasing the Common Stock offered hereby.  This Prospectus contains
forward-looking statements within the meaning of Section 27A of the Securities
Act and Section 21E of the Securities Exchange Act.  Actual results could differ
materially from those projected in these forward-looking statements as a result
of a variety of factors, including those set forth below and elsewhere in this
Prospectus.

     Fluctuations in Quarterly Operating Results.  Ascend has experienced rapid
quarterly growth in net sales principally due to the emergence of several
markets for bandwidth on demand network access products, increased market
acceptance of Ascend's products and the expansion of Ascend's product line and
distribution channels.  Due to the evolving nature of the markets for Ascend's
products, as well as the likelihood of increased competition, there can be no
assurance that Ascend's rate of growth in net sales will continue or that Ascend
will be able to sustain profitability in the future.  Ascend's quarterly
operating results are affected by a wide variety of factors, including
competition, the mix of products sold, the mix of distribution channels
employed, Ascend's success in developing, introducing and shipping new products,
price reductions for Ascend's products, changes in the levels of inventory held
by third party resellers, the timing of orders from and shipments to customers,
seasonality and general economic conditions.  Ascend expects that its gross
margins could be affected in future periods by price adjustments as a result of
increased competition.  Ascend also expects that its gross margins could be
adversely affected in future periods by increased sales of its Pipeline products
as a percentage of net sales.  These products have lower gross margins than

                                       3
<PAGE>
 
Ascend's other products.  In addition, Ascend's use of third parties to
distribute its products to certain VARs may adversely affect Ascend's gross
margins.  Ascend typically operates with a relatively small backlog.  As a
result, quarterly sales and operating results generally depend on the volume and
timing of and ability to fulfill orders received within the quarter, which are
difficult to forecast.  A significant portion of Ascend's expense levels is
relatively fixed in advance based in large part on Ascend's forecasts of future
sales.  If sales are below expectations in any given quarter, the adverse impact
of the shortfall on Ascend's operating results may be magnified by Ascend's
inability to adjust spending to compensate for the shortfall.  Ascend may also
increase spending in response to competition or to pursue new market
opportunities.  Accordingly, there can be no assurance that Ascend will be able
to sustain profitability in the future, particularly on a quarter-to-quarter
basis.

     Dependence on the Internet Access Market; Developing Markets; Market
Acceptance of Ascend's Products.  The recent growth in Ascend's net sales has
been largely attributable to the use of its products for Internet access.  Sales
of Ascend's MAX products, which are used principally as POP termination devices
by ISPs, accounted for approximately 26%, 63% and 81% of Ascend's net sales in
1994, 1995 and the first nine months of 1996, respectively.  Similarly, sales of
Ascend's Pipeline products, which are used for Internet access by Internet
subscribers, were approximately 10%, 20% and 13% of net sales in 1994, 1995 and
the first nine months of 1996, respectively.  The market for Internet access
products is new and evolving, and it is difficult to predict its size or future
growth rate.  Ascend believes that sales of its MAX and Pipeline products will
depend in large part upon a robust industry and infrastructure for providing
Internet access and carrying Internet traffic and upon sustained adoption by
end-user customers of the Internet for commerce and communication.  There can be
no assurance that this industry and infrastructure will develop or that this
adoption will occur.  Ascend believes competition in these markets will increase
significantly in the future and could adversely affect Ascend's business,
results of operations and financial condition.

     In addition, market acceptance of Ascend's products for applications other
than Internet access is important to Ascend's future success.  Specifically,
Ascend's products are targeted at access to corporate backbone networks and
local area networks ("LANs") by remote offices, telecommuters and mobile users,
videoconferencing and multimedia access facilities.  Ascend's success in
generating significant sales in these emerging markets will depend in part on
its ability to educate users about the benefits of Ascend's technology and to
develop effective distribution channels to address these markets.  These markets
are diverse and rapidly evolving, and it is difficult to predict their potential
size or future growth rate.  Moreover, Ascend's limited resources relative to
certain of its competitors may restrict its ability to remain current with
respect to developments in these markets and to effectively pursue marketing
activities in multiple markets simultaneously.  Accordingly, there can be no
assurance that Ascend's products will be widely accepted in these new markets or
that Ascend will be able to identify additional markets.  The inability of
Ascend to continue to penetrate the various markets for its products or to
successfully expand the markets for its products would have a material adverse
effect on its business, results of operations and financial condition.

     Reliance on Sales to Internet Service Providers. In North America, Ascend
sells a substantial percentage of its products, particularly its MAX products,
to ISPs. Sales to ISPs accounted for approximately 21% and 23% of Ascend's net
sales in 1995 and the nine months ended September 30, 1996, respectively. Sales
to one of these ISPs, UUNET, accounted for approximately 11% and 10% of net
sales in 1995 and the nine months ended September 30, 1996, respectively.
Because Ascend's products are being used to enhance or extend the Internet
access infrastructure of the ISPs, Ascend expects that sales to any particular
ISP may vary considerably from period to period. Accordingly, there can be no
assurance that sales to these entities, individually or as a group, will equal
or exceed historical levels in any future period. Any development that would
result in a substantial decrease or delay in sales to one or more of these
entities, including actions by competitors or technological changes, could have
a material adverse effect on Ascend's business, results of operations and
financial condition.

     Integration of Recent Acquisitions. Ascend has completed several
acquisitions of businesses, products or technologies since the beginning of
1995. These have included the acquisition of Morning Star Technologies, Inc.,
NetStar, Inc. and Subspace Communications, Incorporated, which were completed in
1996, as well as the StonyBrook Merger, which was completed in December 1996.
Ascend anticipates that it may acquire additional businesses, products or
technologies in the future, although there are currently no agreements with
respect to such transactions. Achieving the anticipated benefits of past and
future acquisition transactions will depend in part upon whether the integration
of
                                       4
<PAGE>
 
the acquired companies' businesses with Ascend's businesses is accomplished in
an efficient and effective manner, and there can be no assurance that this will
occur. The combination of Ascend with such acquired companies will require,
among other things, integration of the companies' respective product offerings
and technology and coordination of their research and development, sales and
marketing and financial reporting efforts. There can be no assurance that such
integration will be accomplished smoothly or successfully. If significant
difficulties are encountered in the integration of the existing product lines
and technology, resources could be diverted from new product development,
resulting in delays in new product introductions. The integration of the product
lines could also cause confusion or dissatisfaction among existing customers of
Ascend and the acquired companies. The difficulties of such integration may be
increased by the necessity of coordinating geographically separated
organizations with distinct cultures. The integration of certain operations
following an acquisition will require the dedication of management and other
personnel resources which may temporarily distract attention from the day-to-day
business of Ascend. Failure to successfully accomplish the integration of the
operations of Ascend and the acquired companies could have a material adverse
effect on Ascend's business, financial condition or results of operations.

     New Product Development and Timely Introduction of New and Enhanced
Products.  The markets for Ascend's products are characterized by rapidly
changing technologies, evolving industry standards, frequent new product
introductions and short product life cycles.  Inherent in the product
development process are a number of risks.  The development of new,
technologically advanced products is a complex and uncertain process requiring
high levels of innovation, as well as the accurate anticipation of technological
and market trends.  The introduction of new or enhanced products also may
require Ascend to manage the transition from older products in order to minimize
disruption in customer ordering patterns, avoid excessive levels of older
product inventories and ensure that adequate supplies of new products can be
delivered to meet customer demand.  There can be no assurance that Ascend will
successfully develop, introduce or manage the transition of new products.
Products may contain undetected or unresolved software errors when they are
first introduced or as new versions are released.  There can be no assurance
that, despite extensive testing, software errors will not be found in new
products or upgrades after commencement of commercial shipments of new or
enhanced products.  The inability of such products to gain market acceptance or
problems associated with new product transitions could adversely affect Ascend's
operating results, particularly on a quarterly basis.

     Competition.  The markets for Ascend's products are highly competitive and
subject to rapid technological change.  Ascend expects competition to increase
in the future as current competitors enhance their product offerings and
additional companies enter the market.  Ascend's current competitors can be
classified into three groups:  manufacturers of WAN and Internet access
equipment, manufacturers of remote LAN access and Internet subscriber access
equipment, and manufacturers of bandwidth on demand products addressing the
needs of the videoconferencing market.  In the WAN and Internet access equipment
market, Ascend primarily competes with Cisco Systems, Inc. ("Cisco"), U.S.
Robotics Corporation and 3Com Corporation ("3Com"), each of which has
substantially greater financial, marketing and technical resources than Ascend.
In the remote LAN access and Internet subscriber access market, competition is
widespread, although few companies have positioned their products specifically
as digital bandwidth on demand network access systems.  Ascend's primary
competitors in this market are Gandalf, Cisco, Shiva and 3Com.  In the
videoconferencing access market, competitors include Madge Networks, Adtran and
Promptus Communications (a subsidiary of GTI).

     Competitive factors in Ascend's markets include core technology, breadth of
product features, product quality and functionality, pricing, marketing and
distribution resources, international certifications and customer service and
support.  Some of Ascend's current and potential competitors have substantially
greater financial, marketing and technical resources than Ascend.  Many also
have established relationships with current and potential customers for Ascend's
products.  Increased competition could result in price reductions, reduced
profit margins or loss of market share, each of which would adversely affect
Ascend's operating results.  There can be no assurance that Ascend will be able
to continue to compete successfully against current and future competitors as
bandwidth on demand markets evolve and competition increases.

     Management of Growth.  Ascend is currently experiencing rapid growth and
expansion, which has placed, and will continue to place, a significant strain on
its administrative, operational and financial resources and increased demands on
its systems and controls.  This growth has resulted in a continuing increase in
the level of responsibility 

                                       5
<PAGE>
 
for both existing and new management personnel. Ascend anticipates that its
continued growth will require it to recruit and hire a substantial number of new
engineering, sales and marketing and managerial personnel. There can be no
assurance that Ascend will be successful at hiring or retaining these personnel.
Ascend's ability to manage its growth successfully will also require Ascend to
continue to expand and improve its operational, management and financial systems
and controls and to expand its manufacturing capacity. If Ascend's management is
unable to manage growth effectively, Ascend's business, results of operations
and financial condition may be materially and adversely affected.

     Reliance on Third Party Value-Added Resellers and Distributors.  Ascend's
sales, to a significant degree, are made through VARs and distributors.
Accordingly, Ascend is dependent upon the continued viability and financial
stability of these VARs and distributors.  While Ascend has contractual
relationships with many of its VARs and distributors, these agreements do not
require the VAR or distributor to purchase Ascend's products and can be
terminated by the VAR or distributor at any time.  There can be no assurance
that any of Ascend's VARs and distributors will continue to market Ascend's
products.  Ascend's VARs and distributors generally offer products of several
different companies, including products that are competitive with Ascend's
products.  Accordingly, there is a risk that these VARs and distributors may
give higher priority to products of other suppliers, thus reducing their efforts
to sell Ascend's products.  Any special distribution arrangements and product
pricing arrangements that Ascend may implement in one or more distribution
channels for strategic purposes could adversely affect gross profit margins for
its products.

     Dependence on Key Personnel.  Ascend's success depends to a significant
degree upon the continuing contributions of its key management, sales, marketing
and product development personnel.  Ascend does not have employment contracts
with its key personnel and does not maintain any key person life insurance
policies.  The loss of key management or technical personnel could adversely
affect Ascend.  Ascend believes that its future success will depend in large
part upon its ability to attract and retain highly-skilled engineering,
managerial, sales and marketing personnel.  Competition for such personnel is
intense, and there can be no assurance that Ascend will be successful in
attracting and retaining such personnel.  Failure to attract and retain key
personnel could have a material adverse effect on Ascend's business, results of
operations and financial condition.

     Tariff and Regulatory Matters.  Rates for telecommunications services are
governed by tariffs of licensed carriers that are subject to regulatory
approval.  Future changes in these tariffs could have a material effect on
Ascend's business.  For example, should tariffs for public switched digital
services increase in the future relative to tariffs for private leased services,
the cost-effectiveness of Ascend's products would be reduced, and its business
and results of operations could be adversely affected.  In addition, Ascend's
products must meet standards and receive certification for connection to the
public telecommunications network prior to their sale.  In the United States,
Ascend's products must comply with Part 15(a) (industrial equipment), Part 15(b)
(residential equipment) and Part 68 (analog lines) of the Federal Communications
Commission's regulations.  Ascend's products also must be certified by domestic
telecommunications carriers.  In countries outside the United States, Ascend's
products are subject to a wide variety of governmental review and certification
requirements.  In addition, customers outside the United States typically
require that Ascend's products receive certification from their country's
primary telecommunications carriers.  Any future inability to obtain on a timely
basis or retain domestic certification or foreign regulatory approvals could
have a material adverse effect on Ascend's business and results of operations.

     Dependence on Contract Manufacturers and Single-Source Suppliers.  Ascend's
production operations consist primarily of materials planning and procurement,
quality control and final assembly, burn-in and testing of certain products.
Ascend relies on independent contractors to manufacture certain of Ascend's
products or components and subassemblies used in Ascend's products to its
specifications.  Ascend is also dependent upon single or limited source
suppliers for a number of components and parts used in its products, including
certain key microprocessors and integrated circuits.  There can be no assurance
that these independent contractors and suppliers will be able to meet Ascend's
future requirements for manufactured products, components and subassemblies.
Ascend generally purchases single or limited source components pursuant to
purchase orders and has no guaranteed supply arrangements with these suppliers.
In addition, the availability of many of these components to Ascend is dependent
in part on Ascend's ability to provide its suppliers with accurate forecasts of
its future requirements.  Ascend has generally been able to obtain adequate
supplies of parts and components in a timely manner from existing 

                                       6
<PAGE>
 
sources and endeavors to maintain inventory levels adequate to guard against
interruptions in supplies. Ascend believes that there are alternative suppliers
or alternative components for all of the components contained in its products.
However, any extended interruption in the supply of any of the key components
currently obtained from a single or limited source or the time necessary to
transition a replacement supplier's product or a replacement component into
Ascend's products could disrupt its operations and have a material adverse
effect on Ascend's operating results in any given period. Ascend purchases
certain components from suppliers outside the United States; however, all such
purchases are denominated in U.S. dollars and Ascend believes all such
components or alternate components are available from suppliers within the
United States. Ascend may also be subject to increases in component costs, which
could also have a material adverse effect on its operating results.

     Dependence on Proprietary Technology.  Ascend's success and ability to
compete depend in part upon its proprietary technology.  Ascend relies on a
combination of patent, copyright and trade secret laws and non-disclosure
agreements to protect its proprietary technology.  Ascend currently holds two
United States patents and one foreign patent and has three patent applications
pending.  There can be no assurance that patents will be issued with respect to
pending or future patent applications or that Ascend's patents will be upheld as
valid or will prevent the development of competitive products.  In addition,
Ascend has generally entered into confidentiality or license agreements with its
employees, VARs, distributors, customers and potential customers and limits
access to the distribution of its software, documentation and other proprietary
information.  There can be no assurance that the steps taken by Ascend to
protect its proprietary rights will be adequate to prevent misappropriation of
its technology or that Ascend's competitors will not independently develop
technologies that are substantially equivalent or superior to Ascend's
technology.  In addition, the laws of some countries do not protect proprietary
rights to the same extent as do the laws of the United States.  Ascend is also
subject to the risk of adverse claims and litigation alleging infringement of
the intellectual property rights of others.  From time to time, Ascend has
received claims of infringement of other parties' proprietary rights.  Although
Ascend believes that all such claims received to date are immaterial, there can
be no assurance that third parties will not assert infringement claims in the
future with respect to current or future products or that any such claims will
not require Ascend to enter into license arrangements or result in protracted
and costly litigation, regardless of the merits of such claims.  No assurance
can be given that any necessary licenses will be available or that, if
available, such licenses can be obtained on commercially reasonable terms.

     International Sales.  Ascend's international sales accounted for
approximately 15%, 20%, 29% and 45% of Ascend's net sales in 1993, 1994, 1995
and the nine months ended September 30, 1996, respectively.  International sales
are expected to continue to account for a significant portion of Ascend's net
sales in future periods.  International sales are subject to certain inherent
risks, including unexpected changes in regulatory requirements and tariffs,
difficulties in staffing and managing foreign operations, longer payment cycles,
problems in collecting accounts receivable and potentially adverse tax
consequences.  Ascend depends on third party resellers for substantially all of
its international sales.  Certain of these third party resellers also act as
resellers for competitors of Ascend and could devote greater effort and
resources to marketing competitive products.  The loss of certain of these third
party resellers could have a material adverse effect on Ascend's business and
results of operations.  Although Ascend's sales are denominated in U.S. dollars,
fluctuations in currency exchange rates could cause Ascend's products to become
relatively more expensive to customers in a particular country, leading to a
reduction in sales or profitability in that country.  Furthermore, future
international activity may result in foreign currency denominated sales, and, in
such event, gains and losses on the conversion to U.S. dollars of accounts
receivable and accounts payable arising from international operations may
contribute to fluctuations in Ascend's results of operations.  In addition,
sales in Europe and certain other parts of the world typically are adversely
affected in the third quarter of each calendar year as many customers and end-
users reduce their business activities during the summer months.  These seasonal
factors may have an effect on Ascend's business, results of operations and
financial condition.

     Potential Issuance of Preferred Stock; Anti-Takeover Provisions.  The Board
of Directors of Ascend has the authority to issue up to 2,000,000 shares of
Preferred Stock and to fix the rights, preferences, privileges and restrictions,
including voting rights, of these shares without any further vote or action by
the stockholders.  The rights of the holders of the Ascend Common Stock will be
subject to, and may be adversely affected by, the rights of the holders of any
Preferred Stock that may be issued in the future.  The issuance of the Preferred
Stock, while providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of making it
more difficult for a third party to acquire a majority of the outstanding voting
stock of Ascend, thereby 

                                       7
<PAGE>
 
delaying, deferring or preventing a change in control of Ascend. Furthermore,
such Preferred Stock may have other rights, including economic rights, senior to
the Ascend Common Stock, and as a result, the issuance of such stock could have
a material adverse effect on the market value of the Ascend Common Stock. Ascend
has no present plans to issue shares of Preferred Stock. Ascend may in the
future adopt other measures that may have the effect of delaying, deferring or
preventing a change of control of Ascend. Certain of such measures may be
adopted without any further vote or action by Ascend's stockholders. Ascend is
also afforded the protections of Section 203 of the Delaware General Corporation
Law, which could delay or prevent a change in control of Ascend, impede a
merger, consolidation or other business combination involving Ascend or
discourage a potential acquiror from making a tender offer or otherwise
attempting to obtain control of Ascend.

     Volatility of Stock Price.  Ascend's Common Stock has experienced
significant price volatility and such volatility may occur in the future,
particularly as a result of quarter-to-quarter variations in the actual or
anticipated financial results of Ascend or of other companies in the network
access industry or announcements by Ascend or its competitors regarding new
product introductions or other developments affecting Ascend.  In addition, the
market has experienced extreme price and volume fluctuations that have affected
the market price of many technology companies' stocks and that have been
unrelated or disproportionate to the operating performance of these companies.

                              SELLING STOCKHOLDERS

     The Selling Stockholders hold Shares which were issued by the Company in
the StonyBrook Merger or upon exercise  of Options assumed by the Company
pursuant to the StonyBrook Merger.  The Options were originally granted by
StonyBrook pursuant to StonyBrook's 1992 Stock Option Plan.

     The table below lists the Selling Stockholders, the number of shares of
Ascend Common Stock which each owned as of February 7, 1997, the number of
Shares subject to sale pursuant to this Registration Statement, and the number
of the shares of Ascend Common Stock which each would own assuming that such
number of Shares were offered and assuming the sale of all such Shares.

1    The persons named in the table have sole voting and investment power with
     respect to all shares of Ascend Common Stock shown as beneficially owned by
     them, subject to community property laws, where applicable.


     In connection with the filing of this Registration Statement, Ravi Gulati
has entered into a Registration and Stock Trading Agreement with the Company, a
copy of which is filed as Exhibit 4.1 hereto.  Pursuant to that Registration and
Stock Trading Agreement, Mr. Gulati has agreed not to sell, transfer, pledge, or
otherwise dispose of, or reduce his interest in or risk relating to, any shares
of Ascend Common Stock issued to him pursuant to the Merger or upon exercise of
any Assumed Options until after such time as the Company has published (within
the meaning of SEC Accounting Series Release No. 135, as amended) financial
results covering at least 30 days of combined operations of the Company and
StonyBrook.  The Registration and Stock Trading Agreement also provides that
from and after the publication of such results, Mr. Gulati may sell or otherwise
dispose of the shares of Ascend Common Stock registered pursuant to this
Agreement, subject to the following restrictions:

          (i) Mr. Gulati shall not offer, sell, exchange, pledge, transfer or
     otherwise dispose of or engage in any Sale Equivalent Transaction with
     respect to, any of the shares of Ascend Common Stock issued or issuable in
     the Merger unless at such time such transaction shall be permitted pursuant
     to the provisions of SEC Rule 145 under the Securities Act (including any
     applicable limitations on the amount of Ascend Common Stock to be sold as
     set forth in Rule 145(d)(1) and the provisions of Rule 144 referred to
     therein), or he shall have furnished to Ascend an opinion of counsel,
     satisfactory to Ascend, to the effect that no registration under the
     Securities Act would be required in connection with the proposed offer,
     sale, exchange, pledge, transfer or other disposition or transaction, or a
     Registration Statement under the Securities Act covering the proposed
     offer, sale, exchange, pledge, transfer or other disposition or Sale
     Equivalent Transaction shall be effective under the Securities Act;

          (ii) Mr. Gulati shall not offer or sell any of the shares of Ascend
     Common Stock issued or issuable to him in the Merger except during such
     periods as directors, officers and Affiliates of Ascend 

                                       9
<PAGE>
 
     are permitted to purchase and sell Ascend Common Stock pursuant to the
     insider trading policies of Ascend (the "Window Periods"); and
                                              --------------

          (iii) during the effective period of the Registration Statement, Mr.
     Gulati shall (A) offer for sale under the Registration Statement only those
     shares of Ascend Common Stock which were issued to him pursuant to the
     Merge Agreement and are registered under the Registration Statement;
     (B) sell such shares in accordance with and subject to the
     terms, conditions and covenants set forth in this Agreement and in the
     Registration Statement; (C) to the extent required by applicable law, cause
     to be furnished to any purchaser of such shares, and to the broker-dealer,
     if any, through whom such shares may be offered, a copy of the final
     prospectus contained in the Registration Statement, as supplemented or
     amended through the date of the sale (the "Prospectus"); (D) not engage in
                                                ----------
     any stabilization activity in connection with any Ascend securities other
     than as permitted under the Exchange Act; and (E) not bid for or purchase
     any securities of Ascend or any rights to acquire Ascend securities, or
     attempt to induce any person to purchase any Ascend securities (except for
     Mr. Gulati's shares of Ascend Common Stock to be sold to such person by
     means of the Prospectus) or any rights to acquire Ascend securities other
     than as permitted under the Exchange Act.


The foregoing restrictions set forth in subparagraph (ii) above shall cease
without further action by Mr. Gulati or the Company upon and in the event of the
death of Mr. Gulati and the Company shall amend the Registration Statement to
the extent (if any) necessary to permit Mr. Gulati's estate, personal
representative(s), devisees and heirs, as the case may be to resell Mr. Gulati's
remaining shares pursuant to the Registration Statement.

     In addition, each Selling Stockholder (other than Mr. Gulati) has entered
into a Registration and Option Stock Trading Agreement with the Company, the
form of which is filed as Exhibit 4.2 hereto.  Pursuant to the Registration and
Option Stock Trading Agreements, each such Selling Stockholder has agreed not to
sell, transfer, pledge, or otherwise dispose of, or reduce such Selling
Stockholder's interest in or risk relating to, any shares of Ascend Common Stock
issued to such Selling Stockholder pursuant to the Merger or upon exercise of
any Assumed Options until after such time as the Company has published (within
the meaning of SEC Accounting Series Release No. 135, as amended) financial
results covering at least 30 days of combined operations of the Company and
StonyBrook.  From and after the publication of such results, such Selling
Stockholder may sell or otherwise dispose of the shares of Ascend Common Stock
registered pursuant to this Agreement, subject to the following restrictions:

          (i) such Selling Stockholder shall not offer, sell, exchange,
     pledge, transfer or otherwise dispose of or engage in any Sale Equivalent
     Transaction with respect to, any of the shares of Ascend Common Stock
     issued or issuable upon exercise of such Selling Stockholder's Assumed
     Options unless at such time such transaction shall be permitted pursuant to
     the provisions of SEC Rule 145 under the

     Securities Act (including any applicable limitations on the amount of
     Ascend Common Stock to be sold as set forth in Rule 145(d)(1) and the
     provisions of Rule 144 referred to therein), or such Selling Stockholder
     shall have furnished to Ascend an opinion of counsel, satisfactory to
     Ascend, to the effect that no registration under the Securities Act would
     be required in connection with the proposed offer, sale, exchange, pledge,
     transfer or other disposition or Sale Equivalent Transaction, or a
     Registration Statement under the Securities Act covering the proposed
     offer, sale, exchange, pledge, transfer or other disposition or Sale
     Equivalent Transaction shall be effective under the Securities Act;

          (ii) such Selling Stockholder shall not offer or sell any of the
     shares of Ascend Common Stock issued or issuable upon exercise of such
     Selling Stockholder's Assumed Options except during such periods as
     directors, officers and Affiliates of Ascend are permitted to purchase and
     sell Ascend Common Stock pursuant to the insider trading policies of Ascend
     (the "Window Periods"); and
           --------------

          (iii) during the effective period of the Registration Statement, such
     Selling Stockholder shall (A) offer for sale under the Registration
     Statement only those shares of Ascend Common Stock which were issued to
     such Selling Stockholder upon exercise of the Assumed Options and are
     registered under the Registration Statement; (B) sell such shares in
     accordance with and subject to the terms, conditions and covenants set
     forth in this Agreement and in the Registration Statement; (C) to the
     extent required by applicable law, cause to be furnished to any purchaser
     of such shares, and to the broker-dealer, if any, through whom such shares
     may be offered, a copy of the final prospectus contained in the
     Registration Statement, as supplemented or amended through the date of the
     sale (the "Prospectus"); (D) not engage in any stabilization activity in
                ----------
     connection with any Ascend securities other than as permitted under the
     Exchange Act; and (E) not bid for or purchase any securities of Ascend or
     any rights to acquire Ascend securities, or attempt to induce any person to
     purchase any Ascend securities (except for such Selling Stockholder's
     shares of Ascend Common Stock to be sold to such person by means of the
     Prospectus) or any rights to acquire Ascend securities other than as
     permitted under the Exchange Act.

The foregoing restrictions set forth in subparagraph (ii) above shall
cease without further action by such Selling Stockholder or the Company upon and
in the event of the death of such Selling Stockholder and the Company shall 
amend the Registration Statement to the extent (if any) necessary to permit such
Selling Stockholder's estate, personal representative(s), devisees and heirs, as
the case may be to resell such Selling Stockholder's remaining shares pursuant 
to this Registration Statement.

     The foregoing is a brief summary of certain provisions of the Registration
and Stock Trading Agreement, a copy of which is filed as Exhibit 4.1 to the
Registration Statement and incorporated herein by reference, and the
Registration and Option Stock Trading Agreements, the form of which is filed as
Exhibit 4.2 to the registration statement and incorporated herein by reference.
The foregoing summary is qualified in all respects by reference to the full text
of each agreement.  In case of any conflict between the foregoing summary and
the applicable agreement, the applicable agreement will control.

                                 PLAN OF DISTRIBUTION

     Any or all of the Shares may be sold from time to time to purchasers
directly by any of the Selling Stockholders.  Alternatively, the Selling
Stockholders may from time to time offer the Shares through underwriters,
dealers or agents who may receive compensation in the form of underwriting
discounts, concessions or commissions from the Selling Stockholders and/or the
purchasers of Shares for whom they may act as agents.  The Selling Stockholders
and any such underwriters, dealers or agents that participate in the
distribution of Shares may be deemed to be underwriters, and any profit on the
sale of the Shares by them and any discounts, commissions or concessions
received by them may be deemed to be underwriting discounts and commissions
under the Securities Act.  The Shares may be sold from time to time in one or
more transactions at a fixed offering price, which may be changed, or at varying
prices determined at the time of sale or at negotiated prices. The Selling 
Stockholders may from time to time enter into hedging transactions with respect 
to the Shares.

     At the time a particular offer of Shares is made, to the extent required, a
supplement to this Prospectus will be distributed which will identify and set
forth the aggregate amount of Shares being offered and the terms of the
offering, including the name or names of any underwriters, dealers or agents,
the purchase price paid by any underwriter for Shares purchased from the Selling
Stockholders, any discounts, commissions and other items constituting
compensation from the Selling Stockholders and/or the Company, and any
discounts, commissions or concessions allowed or reallowed or paid to dealers,
including the proposed selling price to the public.  The Company will not
receive any of the proceeds from the sale by the Selling Stockholders of the
Shares offered hereby.

     Under applicable rules and regulations under the Exchange Act, any person
engaged in a distribution of the Shares may not simultaneously engage in market
making activities with respect to the Shares for a period of nine business days
prior to the commencement of such distribution.  In addition, and without
limiting the foregoing, the Selling Stockholders will be subject to applicable
provisions of the Exchange Act and the rules and regulations thereunder
including, without limitation, Rules 10b-2, 10b-6 and 10b-7, which provisions
may limit the timing of purchases and sales of the Shares by the Selling
Stockholders.

     In order to comply with certain states' securities laws, if applicable, the
Shares will be sold in such jurisdictions only through registered or licensed
brokers or dealers.  In certain states the Shares may not be sold unless the
Shares have been registered or qualified for sale in such state, or unless an
exemption from registration or qualification is available and is obtained.

     The Company has agreed to indemnify in certain circumstances the Selling
Stockholders and the broker-dealers who may be deemed to be underwriters (if
any) of the securities covered by the Registration Statement against certain
liabilities, including liabilities under the Securities Act. The Selling
Stockholders have agreed to indemnify in certain circumstances the Company
against certain liabilities, including liabilities under the Securities Act.

     The Company has agreed to use its best efforts to keep the Registration
Statement, of which this Prospectus constitutes a part, effective until the
earlier of (i) December 27, 1998, (ii) the date on which the Selling
Stockholders can sell all the Shares pursuant to Rule 144 of the Security Act,
