4.       CONTINGENCIES

         Certain third parties have  expressed  their belief that certain of the
         Company's products may infringe patents held by them and have suggested
         that the Company acquire licenses to such patents. The Company believes
         that licenses, to the extent required,  will be available;  however, no
         assurance can be given that the terms of any offered  licenses would be
         favorable to the  Company.  Management,  after review and  consultation
         with  counsel,   believes   that  the  ultimate   resolution  of  these
         allegations  is  uncertain  and there can be no  assurance  that  these
         assertions  will be resolved  without costly  litigation or in a manner
         that is not  adverse to the  Company.  While the  Company  has  accrued
         certain  amounts  for these  matters in prior  years,  it is  currently
         unable to



                                        7
<PAGE>

         estimate the possible loss or range of loss  regarding  these  matters.
         Therefore,  the ultimate  resolution  of these  matters could result in
         payments in excess of the amounts accrued in the accompanying financial
         statements  and  require  royalty  payments  in the future  which could
         adversely impact gross margins.

         In April 1996, a class action  complaint  was filed against the Company
         and certain of its officers and  directors in the Santa Clara  Superior
         Court of the State of California, alleging violations of the California
         Corporations Code and California Civil Code. In October 1996, a similar
         parallel lawsuit against the Company and the same individuals was filed
         in the  United  States  District  Court for the  Northern  District  of
         California  alleging  violations of the federal  securities  laws.  The
         class period in both of these  lawsuits  runs from  September  12, 1994
         through  December  29,  1995,  and  both  complaints  allege  that  the
         defendants concealed and/or misrepresented material adverse information
         about the Company and that the individual defendants sold shares of the
         Company's  stock  based  upon  material  nonpublic   information.   The
         complaints seek  unspecified  monetary  damages.  To date, the Superior
         Court has  dismissed  portions of  plaintiff's  state  court  complaint
         without leave to amend.  The Superior  Court also dismissed five of the
         individual defendants without the leave to amend. Plaintiff has filed a
         third  amended  complaint  that names the Company and three  individual
         defendants.  Discovery  to date has been  limited  in the  state  court
         action, and the Superior Court has not set a trial date. In the federal
         action,  the Court granted the Company's  motion to dismiss the federal
         complaint  with leave to amend on September 11, 1997, and plaintiff has
         filed an  amended  complaint.  The  Company  has moved to  dismiss  the
         amended  complaint.  A hearing  on the motion to  dismiss  the  amended
         complaint  is  scheduled  for  September  4,  1998.  There  has been no
         discovery in the federal action, and no trial date has been set.

         The Company believes that both actions are without merit and intends to
         defend  both  actions  vigorously.  However,  litigation  is subject to
         inherent  uncertainties and, thus, there can be no assurance that these
         lawsuits  will be resolved  favorably  to the Company or that they will
         not have a material adverse affect on the Company's financial condition
         and results of  operations.  No provision  for any  liability  that may
         result upon  adjudication has been made in the  accompanying  financial
         statements.

5.       RECENT ACCOUNTING PRONOUNCEMENT

         The Company  has  adopted the  provisions  of  Statement  of  Financial
         Accounting  Standards  No.  130,  "Reporting   Comprehensive   Income,"
         effective  January 1, 1998.  This statement  requires the disclosure of
         comprehensive income and its components in a full set of general-



                                       8
<PAGE>


         purpose financial  statements.  Comprehensive  income is defined as net
         income plus revenues,  expenses, gains and losses that, under generally
         accepted  accounting  principles,  are  excluded  from net income.  The
         component  of  comprehensive  income,  which is excluded by the Company
         from  net  income  is the  change  in the  unrealized  gain  or loss on
         securities,   and  this  has  been  included  in  the   computation  of
         comprehensive income.

         In June 1997, the Financial Accounting Standards Board issued Statement
         of Financial Accounting Standards No. 131,  "Disclosures About Segments
         of  an  Enterprise  and  Related   Information"   ("SFAS  131"),  which
         supersedes  Statement of  Financial  Accounting  Standards,  "Financial
         Reporting for Segments of a Business  Enterprise" ("SFAS 14"). SFAS 131
         changes current  practice under SFAS 14 by establishing a new framework
         on which to base segment  reporting and also requires interim reporting
         of segment  information.  This  statement is effective for fiscal years
         beginning  after December 15, 1997. The statement's  interim  reporting
         disclosures  are not  required  until  the  first  quarter  immediately
         subsequent to the fiscal year in which SFAS 131 is effective.

6.       ACQUISITION OF ASSETS OF SEMAPHORE COMMUNICATIONS CORPORATION

         On April 3, 1998, the Company entered into an Asset Sale Agreement (the
         "Agreement")  with  Semaphore  Communications  Corporation,  a Delaware
         corporation ("Semaphore"),  to acquire substantially all of Semaphore's
         non-cash assets (excluding furniture and fixtures) (the "Assets"). This
         acquisition of assets (the "Asset  Acquisition")  was consummated as of
         such date.  Semaphore is a supplier of security  management and virtual
         private  network  solutions  for   Internet/intranet  and  Frame  relay
         applications.

         The Assets  acquired  pursuant to the  Agreement  include  intellectual
         property, inventory, trade receivables and rights under certain assumed
         contracts. Under the terms of the Agreement, the Company issued 291,182
         shares of the  Company's  Common  Stock (the  "Shares")  to  Semaphore,
         valued  at  approximately  $3,200,000,  on  April 3,  1998 and  assumed
         certain  liabilities  (the  "Liabilities").   The  Liabilities  include
         certain   obligations   under  assumed   contracts  and  under  various
         outstanding  purchase orders as well as certain  warranty  obligations.
         The  Company  received  $182,000  from  Semaphore  with  respect to the
         assumption of certain of such Liabilities.  In addition,  in connection
         with the Asset Acquisition,  approximately 20 of Semaphore's  employees
         became employees of the Company.

ITEM 2.  Management's Discussion And Analysis of Financial Condition and Results
         of Operations

RESULTS OF OPERATIONS

Except for the historical  statements  contained herein, this Form 10-Q contains
forward looking  statements  within the meaning of Section 21E of the Securities
Exchange Act of 1934, as amended (the  "Exchange  Act").  These forward  looking
statements involve a number of risks, known and unknown, and uncertainties, such
as the loss of, or  difference  in actual from  anticipated  levels of purchases
from, the Company's  major  customers,  the impact of  competitive  products and
pricing,  the ability to retain and attract key  personnel and other risks which
are described  throughout  the Company's  reports filed with the  Securities and
Exchange  Commission,  including  its Form 10-K for the year ended  December 31,
1997, and within  "Management's  Discussion and Analysis of Financial  Condition
and Results of  Operations,"  including  under the title "Other Factors That May
Affect Future Operating Results."  The actual results that the  Company achieves
may differ materially from any forward looking  statements due to such risks and
uncertainties.

When used in this Form 10-Q words such as "believes,"  "anticipates," "expects,"
"intends,"  and similar  expressions  are intended to identify  forward  looking
statements,  but are not the exclusive  means of  identifying  such  statements.
Readers are urged to carefully review and consider the various  disclosures made
by the  Company  in this  report  and in the  Company's  reports  filed with the
Securities and Exchange  Commission that attempt to advise


                                       11
<PAGE>


interested  parties  of the risks and  factors  that may  affect  the  Company's
business.

Due to all the foregoing  factors,  the Company  believes that  period-to-period
comparisons  of its results of operations  are not  necessarily  meaningful  and
should not be relied upon as an  indication  of future  performance.  Similarly,
past performances are not necessarily indicative of future results. It is likely
that, in some future quarters, the Company's operating results will be below the
expectations of stock market analysts and investors. In such event, the price of
the  Company's  Common  Stock would  likely be  materially  adversely  affected.
Consequently,  the purchase or holding of the Company's Common Stock involves an
extremely high degree of risk.


Net Sales

Net sales for the  second  quarter of 1998  decreased  25% to  $12,797,000  from
$17,033,000  for the same period of the prior year. Net sales for the six months
ended June 30, 1998 decreased 17% to $27,317,000  from  $33,071,000 for the same
period  of  the  prior  year.  These  decreases  in  net  sales  were  primarily
attributable to a decrease in unit sales of broadband (i.e.,  transmission rates
in excess of T1/E1)  products,  as a result of lower  sales to certain  domestic
carrier  customers,  including MCI, and a decrease in the average selling prices
on certain broadband  products as a result of price reductions made in 1997. The
Company  anticipates that lower sales to certain domestic carrier customers will
continue  for  at  least  the  remainder  of  1998.  In  addition,  the  Company
anticipates  that  this  increased   pricing  pressure  will  continue  for  the
foreseeable  future.  However,  actual  results  could  vary from the  foregoing
forward  looking  statements  in the prior two  sentences  due to,  among  other
factors  set  forth or  referenced  in "Other  Factors  That May  Affect  Future
Operating  Results"  below,  and as a result  of the loss of, or  difference  in
actual from anticipated levels of purchases from, the Company's major customers,
the  impact of  competitive  products  and  pricing  and other  risks  described
throughout this Form 10-Q.

Narrowband  sales in absolute  dollars remained flat but increased to 60% of net
sales in the second  quarter of 1998 as compared to 45% in the second quarter of
1997.  Broadband sales  decreased in absolute  dollars by 45% and decreased as a
percentage of net sales to 40% in the second  quarter of 1998 as compared to 55%
in the second quarter of 1997. Narrowband sales in absolute dollars decreased by
1% but increased to 60% of net sales in the first six months of 1998 as compared
to 50% in the first six months of 1997.  Broadband  sales  decreased in absolute
dollars by 34% and  decreased as a  percentage  of net sales to 40% in the first
six months of 1998 as compared  to 50% for the same period in 1997.  The changes
in  narrowband  sales and  broadband  sales as a  percentage  of net sales  were
primarily due to lower sales of broadband  products to certain  domestic carrier
customers, including MCI.

International  sales,  including  Canada,  represented  26% of net  sales in the
second quarter of 1998 as compared to 19% in the second quarter of 1997, and 22%
of net sales for the first six  months of 1998 as  compared  to 17% for the same
period of the prior year.  These  increases  were



                                       12
<PAGE>

primarily  due to sales of the products  developed  by Semaphore  Communications
Corporation  ("Semaphore")  that the  Company  acquired in  connection  with the
acquisition  of  Semaphore  in April  1998.  International  sales are subject to
inherent  risks,  including  difficulties  in  homologating  products  in  other
countries,  difficulties in staffing and managing  foreign  operations,  greater
difficulty  in  accounts  receivable  collection,   and  unexpected  changes  in
regulatory  requirements  and  tariffs,  which may in the future  contribute  to
fluctuations in the Company's business and results.

Gross Profit

Gross profit  decreased  41% in the second  quarter of 1998 to  $5,967,000  from
$10,177,000  for the same period of the prior year.  Gross  profit  decreased to
46.6% of net sales in the  second  quarter of 1998 as  compared  to 59.7% in the
second quarter of 1997.  Gross profit decreased 32% in the six months ended June
30, 1998 to $13,281,000  from $19,399,000 for the same period of the prior year.
Gross profit decreased to 48.6% of net sales for the first six months of 1998 as
compared  to 58.7% for the same  period of the prior year.  These  decreases  in
gross  profit are  primarily a result of decreased  sales  volumes and the above
mentioned price reductions. Gross profits may vary significantly from quarter to
quarter  depending on many factors including  competitive  pricing pressures and
changes in the mix of products  sold.  A  significant  portion of the  Company's
business is very price competitive, which has in the past and will in the future
require  the  Company to lower its  prices,  resulting  in  fluctuations  in the
Company's  business and operating  results.  The Company  anticipates  that this
increased  pricing  pressure  will  continue  for  the  foreseeable  future.  In
addition,  the mix of products sold may change to include a higher percentage of
narrowband products which generally have lower gross margins and would therefore
adversely affect the Company's overall gross profits.

Research and Development

The primary  types of expenses  included in  research  and  development  ("R&D")
expenses  are  personnel,   consulting,  prototype  materials  and  professional
services. R&D expenses increased 38% to $3,567,000 in the second quarter of 1998
from  $2,594,000 in the second quarter of 1997.  This increase was due primarily
to an increase in personnel-related  expenses associated with the acquisition of
Semaphore.  As a percentage of net sales,  R&D expenses were 27.9% in the second
quarter  of 1998 as  compared  to 15.2% in  the  second  quarter  of  1997.  R&D
expenses increased 14% to $6,389,000 for the six months ended June 30, 1998 from
$5,627,000  for the same period of the prior year. As a percentage of net sales,
R&D expenses  increased to 23.4% for the first six months of 1998 as compared to
17.0% for the same period of the prior year.  The increases in R&D expenses as a
percentage  of net sales  primarily  is due to lower  sales  volumes  during the
second  quarter and first six months of 1998. The absolute  dollar  increase for
the  six-month  period  is  attributable  to


                                       13
<PAGE>

higher personnel-related  expenses associated with the acquisition of Semaphore.
The Company  anticipates that its R&D expenses,  excluding purchased R&D, for at
least the remainder of 1998 will continue to increase in absolute dollars and as
a percentage of sales as a result of the Company's  acquisition of Semaphore and
the expected on-going development of the Semaphore technology.  However,  actual
results could vary from the foregoing  forward  looking  statement due to, among
other factors set forth or  referenced in "Other  Factors That May Affect Future
Operating  Results,"  below, the Company's  ability to successfully  develop and
market its products,  and the Company's ability to accelerate or defer operating
expenses, achieve revenue levels during such periods and hire new personnel.


All of the Company's R&D expenditures to date have been expensed as incurred. In
the future,  the Company may be required to capitalize a portion of its software
development  costs pursuant to Statement of Financial  Accounting  Standards No.
86,  "Accounting for Costs of Computer  Software to be Sold, Leased or Otherwise
Marketed."


Selling, General and Administrative

The primary types of expenses  included in selling,  general and  administrative
(SG&A) expenses are personnel,  advertising,  other promotional,  and travel and
entertainment.  SG&A  expenses  decreased  14% in the second  quarter of 1998 to
$4,965,000  from  $5,768,000  for  the  same  period  of the  prior  year.  As a
percentage of net sales, SG&A expenses  increased to 38.8% in the second quarter
of 1998 from 33.9% in the second quarter of 1997. SG&A expenses decreased 7% for
the six months ended June 30, 1998 to $9,988,000  from  $10,683,000 for the same
period of the prior year. As a percentage of net sales, SG&A expenses  increased
to 36.6% for the first six months of 1998 from 32.3% for the same  period of the
prior year.  The decreases in SG&A expenses in absolute  dollars were  primarily
due to lower personnel-related expenses and travel and entertainment,  primarily
within the sales organization, and an decrease in consulting fees. The increases
in SG&A expenses as a percentage of net sales were primarily the result of lower
sales volumes during the second quarter and the first six months of 1998.

Purchased Research and Development

The Company  incurred an expense of $2.3 million  related to purchased  research
and development for which technological feasibility had not been achieved in the
second quarter of 1998 related to the acquisition of Semaphore.  Such in-process
technology was valued,  along with other  acquired  assets,  in


                                       14
<PAGE>

accordance with valuation  techniques  commonly used in the technology  industry
and was expensed  upon  acquisition  in  accordance  with  Financial  Accounting
Standards No. 2, "Accounting for Research and Development Costs". See Notes 6 of
Notes to Financial Sections in this Form 10-Q.

Other Income

Other income primarily  includes interest income.  Other income decreased 27% in
the second  quarter of 1998 to $466,000 from $638,000 for the same period of the
prior year. For the six months ended June 30, 1998,  other income  decreased 16%
to  $1,068,000  from  $1,278,000  for the same period of the prior  year.  These
decreases  were  primarily due to lower  interest  income due to lower  interest
rates and lower cash balances.

Provision / Benefit for Income Taxes

The  Company's  effective tax rate  increased to 39% for the second  quarter and
first six months of 1998  compared to 30.5% for the same  periods in 1997.  This
increase is due primarily to the higher rate  available  assuming a carryback of
current year losses compared to the effective tax rate applicable if the Company
were profitable.


LIQUIDITY AND CAPITAL RESOURCES

The Company had working capital of $25.0 million and cash, cash  equivalents and
marketable  securities of $37.3  million at June 30, 1998.  Net cash provided by
operating  activities  was $1.3 million for the first half of 1998 primarily due
to a write-off of purchased R&D, an increase in accounts payable and decrease in
accounts receivable, offset to some extent by net loss and a decrease in accrued
payroll and other accrued  expenses.  Net cash provided by operating  activities
was  $3.3  million  for the  first  half  of 1997  primarily  as a  result  of a
generation  of net income and an increase in  accounts  payable,  offset to some
extent by an increase in inventories and accounts  receivable.  Cash provided by
investing  activities  during  the  first  half of 1998 was  primarily  from the
maturity  of  marketable  securities  of  $21.9  million  offset  by  additional
purchases of marketable  securities of $18.7 million. Cash provided by investing
activities  during the first half of 1997 was  primarily  from the  maturity  of
marketable  securities  of  $8.1  million  offset  by  additional  purchases  of
marketable  securities  of $7.0  million.  Leasehold  improvements  and  capital
equipment  additions were $887,000 in the first half of 1998 as compared to $1.0
million in the first half of 1997.

In  May  1998,  the  Company  approved  the  repurchase  of up to an  additional
1,000,000 shares of Common Stock for cash from time-to-time at market prices and
as market and business conditions warrant, in open market,  negotiated, or


                                       15

block  transactions.  On October 17, 1996, the Company previously  announced its
initial  intentions to repurchase  up to 500,000  shares of Common Stock,  which
shares have been repurchased since that announcement. Net cash used in financing
activities  was $5.7  million  in the first half of 1998,  primarily  due to the
repurchase  of common stock  offset by the  proceeds  from the exercise of stock
options.  Net cash used in  financing  activities  was $1.4 million in the first
half of 1997,  primarily  from the  repurchase  of  common  stock  offset by the
proceeds from the exercise of stock options and employee stock purchases. During
the first six months of 1998, the Company repurchased on the open market a total
of 646,500  shares of common  stock at prices  ranging  from $6.8125 to $11.50 a
share. This stock has subsequently been retired.

The Company  believes that existing cash and cash flows from  operations will be
sufficient to meet its  anticipated  cash  requirements  for working capital and
capital expenditures for at least the next 12 months.

OTHER FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

In addition to the factors set forth above in the  "Management's  Discussion and
Analysis of Financial  Condition and Results of Operations,"  there are a number
of other factors that may affect the Company's future operating results. Most of
the following discussion consists of forward looking statements and accompanying
risks.

The Company  believes that the loss of, or difference in actual from anticipated
levels  of  purchases  from,  the  Company's  major  customers  have in the past
adversely  affected  the  Company  and  could  in the  future  adversely  affect
operating  results.  A significant  portion of the Company's business is derived
from substantial orders placed by large end users and telephone  companies,  and
the timing of such orders,  including the completion of the build out of carrier
and network service providers infrastructures, could cause material fluctuations
in the Company's  business and  operating  results.  For example,  in the fourth
quarter  of 1997 and in the  second  quarter  of 1998,  the  Company  had  lower
operating  results than  expected due in part to a weaker than  expected  demand
from certain  domestic carrier  customers  including MCI. Other factors that may
cause  fluctuations  in the Company's  operating  results  include,  but are not
limited to,  seasonal  capital  spending  patterns of large domestic  customers,
changes in the  product  mix sold toward  narrowband  products  that yield lower
gross margins, the timing of new product  announcements and introductions by the
Company and its  competitors,  changes in sales  volumes  through the  Company's
distribution  channels,  market  acceptance  of new or enhanced  versions of the
Company's  products,  availability  and cost of  components  from the  Company's
suppliers and economic  conditions  generally or in various geographic areas. In
addition,  the Company's expense levels are based in part on its expectations of
future  revenue.  The  Company  operates  with  limited  order  backlog,  and  a
substantial


                                       16
<PAGE>

majority of its  revenues  in each  quarter  result  from orders  booked in that
quarter. If revenue levels are below expectations,  the Company may be unable to
adjust  spending in a timely  manner  which  would  adversely  affect  operating
results. The Company's industry has in the last several years been characterized
by declining prices on existing  products,  therefore  continual  improvement of
manufacturing efficiencies and enhancements to existing products are required to
maintain gross margins.

The market for the Company's products is highly competitive. The Company expects
competition to increase in the future from existing  competitors  and from other
companies that may enter the Company's existing or future markets.  In addition,
the Company faces competition from suppliers of internetworking  equipment, such
as routers,  and telephone  equipment,  such as switches,  which are including a
direct WAN  interface in certain of their  products.  An  increased  reliance by
customers on such suppliers for WAN access would reduce demand for the Company's
products,  which would have a material adverse affect on the Company's  business
and operating results. As discussed above, increased competition has also placed
increasing  pressures  on the  pricing  of the  Company's  products,  which  has
resulted in lower operating results.  The Company  anticipates that this pricing
pressure will continue for the foreseeable future.



The Company's future prospects will depend in part on its ability to enhance the
functionality of its existing WAN access products and DL7100 products  (formerly
known as the W/ATM GateWay Products) in a timely manner and to identify, develop
and achieve market  acceptance of new products that address new technologies and
meet  customer  needs in the WAN access  market.  Any  failure by the Company to
anticipate or to respond  adequately  to  competitive  solutions,  technological
developments in its industry,  changes in customer  requirements,  or changes in
regulatory  requirements or industry standards, or any significant delays in the
development, introduction or shipment of products, could have a material adverse
effect  on  the  Company's  business  and  operating  results.  There  can be no
assurance  that  the  Company's  product  development  efforts  will  result  in
commercially  successful  products  or that  product  delays  will not result in
missed  market  opportunities.   In  addition,   customers  could  refrain  from
purchasing  the  Company's  existing  products  in  anticipation  of new product
introductions by the Company or its competitors.  New products could also render
certain of the  Company's  existing  products  obsolete.  Either of these events
could materially adversely affect the Company's business and operating results.


                                       17

The Company is currently  developing and may in the future develop products with
which the  Company  has only  limited  experience  and/or  that are  targeted at
emerging market segments,  including the Company's  DL7100 product.  The Company
has experienced delays in the development of the DL7100 product, in part related
to technical problems that required some software to be redesigned.  This became
available  for revenue  shipments  in the second  half of 1997.  The Company has
experienced very limited customer interest to date in this product.  The Company
continues to evaluate the long-term  viability of the DL7100 product.  Given its
complexity,  there can be no  assurance  that this  product  will not  encounter
further  technical  or other  difficulties  that could  significantly  delay its
deployment or acceptance or could result in the  termination of the  development
program  for this  product.  There can be no  assurance  that the market for ATM
infrastructure  products will continue to develop, that the DL7100 will meet the
needs of the emerging ATM market or any other market or, that products currently
available or under development by competitors will not directly compete with the
DL7100  product.  The  occurrence  of any of these  events could have a material
adverse affect on the Company's business and operating results.

The Company  believes that its future success will depend in large part upon the
continued  contributions of members of the Company's senior management and other
key  personnel,  and upon its  ability to  attract  and  retain  highly  skilled
managerial,   engineering,   sales,  marketing  and  operations  personnel,  the
competition  for  whom is  intense.  Certain  of the  Company's  key  management
personnel have only recently joined the Company and certain  personnel have only
limited experience in the Company's industry.  In February 1998, Alan I. Fraser,
the Company's  President and Chief  Executive  Officer  resigned to pursue other
interests.  Vinita Gupta, Chairman of the Board, assumed the responsibilities of
President  and Chief  Executive  Officer upon Mr.  Fraser's  departure,  and the
Company is searching  for an  individual  to succeed Ms. Gupta as President  and
Chief  Executive  Officer.  In  addition,  the Company is  searching  for a Vice
President,  Sales. The Company is also currently  attempting to hire a number of
sales and  engineering  personnel  and has  experienced  delays in filling  such
positions. The current availability of qualified sales and engineering personnel
is quite limited, and competition among companies for such personnel is intense.
There can be no assurance  that the Company will be successful in attracting and
retaining skilled personnel to hold these important positions.

The Company completed an acquisition of Performance Telecom in the third quarter
of 1997 and an  acquisition of  substantially  all of the assets of Semaphore in
the  second  quarter of 1998 and may  complete  additional  acquisitions  in the
future.  The process of  integrating  an acquired  company's  business  into the
Company's  operations  may  result  in  unforeseen  operating  difficulties  and
expenditures  and  may  absorb  significant   management  attention  that  would
otherwise be available for the ongoing  development  of the Company's  business.
Moreover,  there  can  be no  assurance  that  the  anticipated  benefits  of an
acquisition  will be realized.  The Company


                                       18
<PAGE>

has experienced declining revenues from the products acquired in the Performance
Telecom acquisition. In addition, acquisitions involve numerous risks, including
difficulties in managing  diverse  geographic sales and research and development
operations,  risks of  entering  markets in which the  Company has no or limited
direct prior  experience,  difficulties in the  assimilation of the technologies
and products of the acquired  companies and the potential  loss of key employees
of the acquired company. The inability of the Company's management to respond to
changing business conditions effectively,  including the changes associated with
its recent  acquisitions,  could have a material adverse affect on the Company's
business, financial condition and results of operations.

The Company has  assessed  and  continues  to assess the impact of the Year 2000
issue on its  operations,  including the  development of cost estimates for, and
the extent of  programming  changes  required to address,  this issue.  Although
final cost  estimates have yet to be  determined,  it is anticipated  that these
Year 2000 costs will not be material to the Company's  expenses  during 1998 and
1999.  The Company does not currently have any  information  concerning the Year
2000 compliance status of its suppliers and customers.  In the event that any of
the  Company's  significant  suppliers or customers  does not  successfully  and
timely achieve Year 2000 compliance,  the Company's business or operations could
be adversely affected.

In April  1996,  a class  action  complaint  was filed  against  the Company and
certain of its officers and directors in the Santa Clara  Superior  Court of the
State of California, alleging violations of the California Corporations Code and
California  Civil Code. In October 1996, a similar  parallel lawsuit against the
Company and the same  individuals  was filed in the United States District Court
for the  Northern  District of  California  alleging  violations  of the federal
securities  laws. The class period in both of these lawsuits runs from September
12,  1994  through  December  29,  1995,  and both  complaints  allege  that the
defendants  concealed and/or  misrepresented  material adverse information about
the  Company and that the  individual  defendants  sold shares of the  Company's
stock based upon material nonpublic information. The complaints seek unspecified
monetary  damages.  To date,  the  Superior  Court  has  dismissed  portions  of
plaintiff's  state court  complaint  without leave to amend.  The Superior Court
also  dismissed  five of the  individual  defendants  without leave to amend and
another individual defendant with leave to amend. The Superior Court also denied
motions to dismiss filed by the Company and two other individual defendants with
respect to the remaining portions of the complaint.  Plaintiff has filed a third
amended  complaint  that  names the  Company  and three  individual  defendants.
Discovery to date has been limited in the state court  action,  and the Superior
Court has not set a trial date.  On September  11, 1997,  the Court  granted the
Company's  motion to dismiss  the  federal  complaint  with leave to amend,  and
plaintiff has filed an amended  complaint.  The Company has moved to dismiss the
amended  complaint.  There has been no discovery in the federal  action,  and no
trial date has been set.  The  Company  believes  that both  actions are without
merit and intends to defend


                                       19
<PAGE>

both   actions   vigorously.   However,   litigation   is  subject  to  inherent
uncertainties  and, thus,  there can be no assurance that these lawsuits will be
resolved  favorably to the Company or that they will not have a material adverse
affect on the  Company's  financial  condition  and  results of  operations.  No
provision for any liability that may result upon  adjudication  has been made in
the accompanying financial statements.

The  telecommunications  industry is  characterized  by the existence of a large
number  of  patents  and  frequent  litigation  based on  allegations  of patent
infringement.  For example, a third party has on several occasions expressed its
belief that certain of the  Company's  products,  including  its  CSU/DSUs,  may
infringe  upon patents held by it and has suggested on such  occasions  that the
Company acquire a license to such patents.  The Company believes that a license,
to the extent required,  will be available;  however,  no assurance can be given
that the terms of any offered license would be favorable to the Company.  Should
a license be unavailable,  the Company could be required to discontinue the sale
of or to redesign certain of its products. In addition, Larscom, a competitor of
the  Company,  has  continued to express its belief that the  Company's  inverse
multiplexer  products may infringe a patent jointly owned by Larscom and a third
party and has suggested  that the Company  acquire a license to the patent.  The
Company  does not believe that there is merit to  Larscom's  claim.  Management,
after  review  and  consultation  with  counsel,   believes  that  the  ultimate
resolution of both these  allegations is uncertain and there can be no assurance
that these assertions will be resolved without costly  litigation or in a manner
that is not adverse to the Company.  While the Company  accrued  certain amounts
for these  matters  in prior  years,  it is  currently  unable to  estimate  the
possible loss or range of loss regarding these matters.  Therefore, the ultimate
resolution  of these  matters  could result in payments in excess of the amounts
accrued in the accompanying financial statements and require royalty payments in
the future which could adversely impact gross margins. There can be no assurance
that other third parties will not assert infringement claims against the Company
in the future, that any such claims will not result in costly litigation or that
the Company will prevail in any such  litigation or be able to license any valid
and infringed patents from third parties on commercially reasonable terms.

The risks outlined  herein are difficult for the Company to forecast,  and these
or other factors can materially affect the Company's operating results and stock
price for one  quarter or a series of  quarters.  Further,  in recent  years the
stock market has  experienced  extreme price and volume  fluctuations  that have
particularly  affected the market prices of  securities of many high  technology
companies,  for reasons frequently unrelated to the operating performance of the
specific companies. These fluctuations,  as well as general economic,  political
and market  conditions may materially  adversely  affect the market price of the
Company's common stock.

The Company has adopted the  provisions  of Statement  of  Financial  Accounting
Standards No. 130, "Reporting  Comprehensive Income," effective January 1, 1998.
This  statement  requires  the  disclosure  of  comprehensive   income  and  its
components in a full set of general-purpose financial statements.  Comprehensive
income is defined as net income plus revenues,  expenses, gains and losses that,
under generally accepted  accounting  principles,  are excluded from net income.
The component of comprehensive income, which is excluded from net income, is the
change in the unrealized gain or loss on securities and has been included in the
computation of comprehensive income.

In June 1997,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards  No.  131,  "Disclosures  About  Segments of an
Enterprise and Related  Information" ("SFAS 131"), which supersedes Statement of
Financial Accounting Standards,  "Financial Reporting for Segments of a Business
Enterprise"  ("SFAS 14").  SFAS 131 changes  current  practice  under SFAS 14 by
establishing  a new  framework  on  which  to base  segment  reporting  and also
requires interim reporting of segment  information.  This statement is effective
for fiscal years  beginning  after  December 15, 1997. The  statement's  interim
reporting  disclosures  are not  required  until the first  quarter  immediately
subsequent to the fiscal year in which SFAS 131 is effective.

PART II. OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

The Company and certain of its  officers  and  directors  are parties to various
lawsuits  described  in  paragraphs  two  and  three  in  Note  4  of  Notes  to
Consolidated  Financial  Statements  in Part I of this Form  10-Q.  See also the
Company's  Form 10-Q for the period  ended  March 31, 1998 and its Form 10-K for
the period ended December 31, 1997 for previous disclosures about such lawsuits.

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

 On April 3,  1998,  the  Company  entered  into an Asset  Sale  Agreement  (the
"Agreement") with Semaphore Communications  Corporation,  a Delaware corporation
("Semaphore"),  to acquire  substantially  all of  Semaphore's  non-cash  assets
(excluding  furniture and fixtures) (the "Assets").  This  acquisition of assets
(the "Asset  Acquisition")  was consummated as of such date. The Assets acquired
pursuant  to the  Agreement  include  intellectual  property,  inventory,  trade
receivables and rights under certain assumed  contracts.  Under the terms of the
Agreement,  the Company issued 291,182 shares of the Company's Common Stock (the
"Shares"), valued at approximately $3,200,000, to Semaphore on April 3, 1998 and
assumed certain liabilities (the "Liabilities"). The Liabilities include certain
obligations  under  assumed  contracts and under  various  outstanding  purchase
orders as well as certain warranty  obligations.  The Company received  $182,000
from Semaphore  with respect to the  assumption of certain of such  Liabilities.
The Shares issued to Semaphore in the Asset Acquisition were issued in a private
placement  pursuant to the exemption from registration  under the Securities Act
of 1933, as amended, under Section 4(2) of such Act.
