BASIS OF PRESENTATION

         The accompanying consolidated financial statements have been prepared
by the Company without audit in accordance with generally accepted accounting
principles for interim financial statements and with instructions to Form 10-Q
and Rule 10-01 of Regulation S-X. In the opinion of management, all adjustments
(consisting only of normal recurring accruals) considered necessary for a fair
presentation have been included.

         The accompanying consolidated financial statements do not include
certain footnotes and financial presentations normally required under generally
accepted accounting principles and, therefore, should be read in conjunction
with the audited financial statements included in the Company's Annual Report on
Form 10-K as at December 31, 1998.

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS FOR THE PERIOD ENDED MARCH 31, 1999

FORWARD LOOKING STATEMENT

         This Form 10-Q contains certain forward looking statements within the
meaning of Section 27A of the Securities Act of 1933, as amended and Section 21E
of the Securities Exchange Act of 1934, as amended. The forward looking
statements involve risks and uncertainties that could cause actual results to
differ materially from those expressed in, or implied by, the forward looking
statements. Factors that might cause such a difference include, but are not
limited to, those relating to: general economic conditions in the markets in
which the Company operates, success in the development and market acceptance of
new and existing products (particularly SONETLYNX, FIBRETRAX, LANSCAPE, and
CS4); dependence on suppliers, third party manufacturers and channels of
distribution; customer and product concentration; fluctuations in customer
demand; maintaining access to external sources of capital; ability to execute
management's margin improvement and cost control plans; overall management of
the Company's expansion; and other risk factors detailed from time to time in
the Company's filings with the Securities and Exchange Commission, including
without limitation those set forth in the Section entitled "Risk factors" in the
form S-3 of the Company filed in April 2, 1999.

THE COMPANY

         The Company is engaged in the business of designing, developing,
manufacturing, marketing and selling products and services for managing digital
signals and converging voice, data and video networks. The Company's current
operations were established through a series of mergers in 1995 and 1996, at
which time four communications product platforms were defined to respond to the
increasing demands of speed and complexity in communications.

         The Company is strategically focusing its product lines and services to
take advantage of the convergence of telecommunications (telecom) and data
communications (datacom). This convergence is being driven by the explosive
growth of Internet applications such as E-commerce, which is accelerating the
expansion of network capacities. These industry trends create requirements for
today's network integrators and directors to manage multiple applications, at
multiple locations, within bandwidth resources and while balancing the need for
network reliability. The Company's product lines are designed to meet these
evolving markets, applications and requirements.

         The Company's objective is to develop and bring to market a new
generation of intelligent, flexible, and scalable communications products
designed to combine current voice, data and video networks (for example,
telephones, computers, surveillance) into a single communications network, which
would also upgrade communications into the latest generation of high-speed
technologies, while using a single network management system.

PRODUCTS, TECHNOLOGIES AND SERVICES

Multi-service Access Platform (MAP)

         This Integrated Access Device (IAD), marketed under the names SONETLYNX
and FIBRETRAX, the Company believes is a revolutionary networking infrastructure
product for public and private networks to cost-effectively create voice, data
and/or video networks of virtually any size and application. It is defined as a
platform because, from its basic architecture, it can be configured into many
separate products for a variety of functions and applications. Through the use
of different protocol cards, the MAP can simultaneously combine multiple
communication transmissions such as video and graphics communications, data
files, voice and any IP-based service over a single network. The products are
compatible with Synchronous Optical Network (SONET) and Synchronous Digital
Hierarchy (SDH) standards in order to provide fail-safe networks. The SONETLYNX
and FIBRETRAX, in addition to providing add-drop multiplexing, provide the
functions of traditional networking equipment such as bridges, channel banks,
routers and video matrix switches, thus offering significant savings in cost and
time for the user when OC-1 or OC-3 bandwidth is required. The MAP expands into
markets horizontally by increasing the types of protocols (applications) it can
transport, and vertically by increasing its capacity (transmission speed).
Currently, the MAP can transport voice, T1/E1, Ethernet (10/100baseT), JPEG
video and low speed data protocols such as RS-232 and RS-422 at speeds up to the
OC-3/STM-1 rate (155 Mbps). Product advancements scheduled during 1999 include



                                       8

<PAGE>   10


adding the protocol cards for ISDN, digital modem pool and Frame Relay as well
as increasing the MAP's transmission speed to the OC-12/STM-4 rate (622 Mbps).
Video and high speed data modules are planned with higher port density. Network
management systems are under development in the Windows NT version. The cost
effectiveness and competition advantage of the MAP are expected to increase with
the addition of each major protocol and increase in transmission speed.

has the capability to conduct up to a three-way conference call without a costly
multiconferencing unit (MCU), transmit video broadcasts using IP multicast, and
use its integrated software to switch between two incoming video sources. Each
incoming video is contained in an individual window which the user can control
as to size and volume. In addition to video conferencing, LANSCAPE features
video record and playback controls for applications such as education/training
and recorded event distribution. LANSCAPE support of IP multicast allows for
transmission of live or pre-recorded video from one to many.

CS4 Intelligent Services Platform

         The Company believes the CS4 represents a revolutionary new class of
product. It is an integrated enhanced network server. Its array of integrated
capabilities transcends traditional product categories to introduce a flexible
system that can host a wide range of intelligent services in a variety of
network configurations. The design of the CS4 positions it to impact the
proliferation and profitability of intelligent services in the network, as well
as to improve the cost paradigm now in place for service nodes, intelligent
peripherals, enhanced service platforms, and programmable switches. Key
technological innovations reflected in the CS4 include highly distributed
processing power to the port level, scalable port capacity that extends up to
64k ports, an advanced call processing structure, a powerful service creation
facility, and an architecture that readily supports integration into low speed,
high speed, and broadband networks, all designed for a fault-tolerant, NEBS
compliant structure.

COMPARISON OF FIRST QUARTER 1999 TO FIRST QUARTER 1998
-------------------------------------------------------------------------------

         The Company believes the financial results for the first quarter of
1999 are not indicative of expected results for the year. The Company is
implementing a new strategy of focusing resources and activities on high growth
markets in networking equipment and digital signal processing. The Company is
concentrating on private and public network access applications involving the
integration, transport and convergence of voice, data and video services.

         Commencing in the second quarter, the Company expects a turnaround in
operations, based on the substantial backlog of orders received so far this
year. The current period marks the fifth quarter impacted by the loss of
substantial business formerly concentrated in Korea. Expenses have been reduced.
Product development spending has been maintained to position the Company for
participation in non-Korean and new growth markets.

         The following table shows the revenue and gross profit for the
Company's products:

NET REVENUE

         The decrease in revenue from fiber optic multiplexer products is mainly
attributable to the loss of shipments to Korea. Non-Korean revenue increased 4%
in 1999 compared to 1998. The Company expects this product line to benefit
materially from new orders and improving operations in following quarters. The
decrease in engineering services revenue reflects a transition to new projects
upon the completion of several large customer programs. Digital signal processor
revenue was delayed and restricted by a temporary shortage of integrated circuit
components from Texas Instruments. Shipments resumed in March 1999, and the
components are expected to be supplied on an allocation basis through June.

GROSS PROFIT

         Gross profit on fiber optic multiplexer products declined as a result
of the lower volume of shipments. Engineering services gross profit declined due
to the lower revenue level. The Company expects the gross profit to increase in
subsequent quarters as a result of higher levels of operations based on the
production and shipment of new orders in backlog.

ENGINEERING AND DEVELOPMENT (E&D) EXPENSE

         Engineering and development expense decreased 14% to $2,433,000 from
$2,845,000 in the prior year period. In addition, $157,000 of software
development costs were capitalized in 1999. The combined totals of these
development costs were distributed by product line as follows:

</TABLE>

         During the first quarter of 1999, the architecture of the SONETLYNX and
FIBRETRAX fiber optic multiplexer product lines were advanced to improve
functionality and cost-effectiveness in support of migration into public carrier
access markets.

         The higher level of CS4 development spending reflects primarily
subsystem testing, systems integration, load testing and performance analysis to
complete beta systems. The field trial phase commenced at the end of the quarter
with delivery of the beta system to the customer site and the initial
implementation of the customer's application.

         Digital signal processing product development included the design of
two new lines of ruggedized VME circuit boards, one based on Texas Instruments'
C6000 DSP processors and the other on PowerPC RISC processors. The Company
believes these next generation products are the centerpiece for the Company's
standard product offering for the harsh environment market.

         Video communication product development continued in the areas of PCI
compliant hardware, H.323 interoperability, and specialized application
interfaces. The Company expects future spending on this product line to be
reduced substantially after the second quarter.

AMORTIZATION OF GOODWILL

         The amount of amortization of goodwill has been reduced $163,000 per
quarter due to the writeoff in September 1998 of goodwill in connection with the
acquisition of Intelect, Inc., which in 1995 was concentrated in the air traffic
control business, no longer a principal line of business for the Company.

SELLING AND ADMINISTRATIVE EXPENSE

         Compared to the prior year period, selling and administrative expenses
were reduced 4% to $3,482,000 from $3,630,000. On March 25, 1999, the Company
announced the closing of three offices dedicated to the video conferencing
product line and consolidated selling operations in order to reduce spending.
See "Expense Reductions" page 14.

INTEREST EXPENSE

         Interest expense decreased to $807,000 from $1,023,000 in the prior
year period. Cash interest costs increased to $385,000 from $320,000 due to the
addition of lines of credit secured by accounts receivable and inventory, offset
by reduced obligations to former shareholders of DNA. The remainder of
reportable interest expense consists of non-cash costs of financings, namely,
amortization of debt discount and deferred financing costs attributable to
valuation of warrants using the Black-Scholes pricing model. Amortization of
approximately $400,000 does not continue after March 1999.

DIVIDENDS ON PREFERRED STOCK

         Preferred dividends include $322,000 and $369,000 in 1999 and 1998,
respectively, which the Company has elected to pay in common stock. Also
reported as dividends are non-cash financing costs of $148,000 and $377,000,
respectively, attributable to the value of beneficial conversion features of the
preferred stock. During the second quarter of 1999, a one-time amount of
$1,037,000 of such non-cash financing costs will be reportable as dividends due
to the issuance of Series E preferred.

YEAR 2000 COMPLIANCE

         The Company has conducted a review of its computer systems and products
to identify those that could be affected by the "Year 2000 Problem," the result
of computer programs using two digits rather than four to define the year
portion of dates. The Company has determined that none of its significant
systems or products fail to distinguish the year 2000 from the year 1900. The
review continues, in an ongoing process, to examine the risk, if any, to the
Company, of vendor or customer exposure to the Year 2000 Problem. To date, no
exposure has been discovered which would have a material adverse effect on the
Company. Certain purchased software, resold or used in company products, has
been certified by the vendors to be compliant. The financial impact of Year 2000
compliance has not been and is not anticipated to be material to the Company's
financial position or results of operations in any given year.

-------------------------------------------------------------------------------
LIQUIDITY AND CAPITAL RESOURCES
-------------------------------------------------------------------------------

         For the three months ended March 31, 1999, cash balances were decreased
by $991,000. During the three month period, cash used in operations,
($4,424,000), and in investing activities, ($829,000), was funded by the
reduction in cash balances and by securing new financing, net of repayments, of
$3,962,000.

OPERATING ACTIVITIES

         Net cash used in operations consisted of the $7,904,000 net loss offset
by the $1,827,000 increase in working capital and by $1,653,000 of non-cash
charges. The net loss primarily reflects the effect of fixed costs in a period
of lower revenue and the continuation of new product development mitigated by
expense reductions in all product lines.

         o        Accounts receivable were a source of funding due to
                  collections from customers of $1,527,000 in excess of new
                  shipments and billings.

         o        The non-cash charges were primarily $1,199,000 depreciation
                  and amortization of intangible assets and $421,000 of
                  amortization of deferred financing costs.

INVESTING ACTIVITIES

         Investments consisted primarily of capitalized software development
costs of $324,000 and capital expenditures of $183,000 for fixed asset
additions. Both elements of investment spending were primarily in support of
SONETLYNX and FIBRETRAX product line enhancements.

FINANCING ACTIVITIES

         Cash uses were financed by the following transactions during the three
month period ended March 31, 1999:

         o        $1,800,000 from the sale of common stock in January

         o        $3,000,000 from the sale of Series E preferred stock in March

         In January, the Company exercised its right to extend the term of the
Credit Facility to February 12, 2000. In March, the term of the Receivables Loan
was extended to February 12, 2000.

LIQUIDITY OUTLOOK

SUBSEQUENT FINANCING ACTIVITIES

         On April 20, 1999, the Company sold $3,000,000 of Series E preferred
stock in a private placement. As disclosed in the Form 8-Ks of the Company filed
on March 2 and March 8, 1999, the Series E preferred stock has a five year term,
an accrued premium of 8% per annum payable in common stock, and is convertible
into common stock at the lesser of a fixed or variable conversion price. The
fixed conversion price is $0.90625 and the variable conversion price is 83.5% of
the average of the two lowest closing bid prices in the forty trading days prior
to the date of conversion. On April 26, 1999, the Company notified the holders
that it is suspending indefinitely any further conversion of the Series E
preferred stock. See below.

DISCONTINUANCE OF CONVERSIONS OF PREFERRED STOCK

         As disclosed in the Form 8-K filed on April 26, 1999, the Company is
discontinuing indefinitely conversions of its outstanding shares of Series C,
Series D, and Series E Convertible Preferred Stock . The Company believes, among
other things, that purchasers of the Series C and Series D preferred stock
violated representations and warranties regarding investment purpose and intent.
The purchasers of the Series E preferred stock made the same representations
regarding investment purpose and intent as they made in connection with their
purchase of the Series C and D preferred stock. No shares of Series E preferred
stock have been submitted for conversion, but should they be, the Company also
will not effect conversions of such shares for an indefinite period of time.

         Although the terms and conditions of the preferred stock provide that,
as a result of the failure to convert, the holders may be entitled to
significant liquidated damages and to require redemption of the preferred stock,
the Company believes there are significant defenses to any claims to enforce
such remedies. In addition, the Company believes there are significant
affirmative claims and remedies available to the Company. However, under present
conditions, if the holders of the preferred stock were ultimately successful in
enforcing a demand for redemption and liquidated damages, the current value of
approximately $16,000,000 would have a material adverse effect on the Company's
financial condition and results of operations.

NASDAQ LISTING STATUS

         The Company is in the process of reviewing with Nasdaq, according to
Nasdaq procedures, the Company's plans and expectations for continued compliance
with listing requirements for the Nasdaq National Market, primarily with respect
to net tangible assets. Nasdaq advised non-compliance based on financial
information contained in the Company's Form 10-K for the period ended December
31, 1998. The Company advised Nasdaq of the Company's expectation of compliance
based upon subsequent events and developments during 1999. Within Nasdaq
procedures, the Company has also stayed a Nasdaq delisting determination at the
staff level by requesting a hearing by the Nasdaq Listing Qualifications Hearing
Department to review Company progress, plans and expectations. There can be no
assurance that the hearing and subsequent processes will result in a
determination favorable to the Company and the Company's common stock will
continue to be listed on the Nasdaq National Market. The inability to maintain
the listing could adversely affect the liquidity of the Company's common stock.
If a delisting continues, a Triggering Event with respect to the Series C,
Series D and Series E preferred stock may occur. Such an event would enable the
holders to demand redemption. Under present conditions, redemption would have a
material adverse effect on the Company's financial condition and results of
operation.

DEBT MATURITIES

         o        The Credit Facility and Receivables Loan, which have an
                  aggregate principal amounts outstanding of $15,000,000, become
                  due on February 12, 2000. The Company intends to refinance
                  those debts at the maturity date, but no assurance can be
                  given that a refinancing can be arranged.

         o        The Inventory Loan with a principal balance of $500,000 and
                  accumulated interest of $9,000 was due in installments on
                  April 1 and May 1, 1999. The Company is in negotiation with
                  the lender to extend the maturity of this obligation.




                                       13

<PAGE>   15

         o        Obligations to two former owners of DNA, having an aggregate
                  principal and interest amount of $433,000, is scheduled for
                  repayment in May and June, 1999.

EXPENSE REDUCTIONS

         On March 25, 1999, the Company announced the closing of three offices
of its Intelect Visual Communications unit and consolidation of operations in
Richardson, Texas, in order to maximize engineering expertise in E&D, achieve
greater utilization of existing sales, marketing and customer service
infrastructures, and to realize expected reductions in overall cost structure in
excess of $2 million on an annualized basis.

CONCLUSION

         The Company has operational, financial and product introduction plans
which, if achieved, will result in profitability and cash equilibrium before the
end of 1999. Considering the available financial resources, current business
prospects, the outlook for cash available from customer collections, the outlook
for cash to be used in operations and investing, and actions to control
spending, the Company believes it has or can obtain the financial resources to
meet its business requirements for the balance of the current year. There can be
no assurance, however, that the assumptions and projections underlying or
supporting this outlook will be realized. The Company has incurred significant
operating losses and negative cash flows from operations in the last three
years. The cash flows were funded by proceeds from borrowings under credit
facilities and by sales of convertible debentures, preferred stock, and common
stock. The Company expects operating losses and negative operating cash flow to
continue at least through mid-year 1999. It is uncertain when, if ever, the
Company will report operating income or positive cash flow from operations. If
cash needs exceed available resources, there also can be no assurance that
additional capital will be available through public or private equity or debt
financings. The financial statements have been prepared assuming the Company
will continue as a going concern and do not include any adjustments that might
result from the unfavorable outcome of such an uncertainty.

CONTINGENT LIABILITIES

         As discussed in "ITEM 3 - Legal Proceedings" in the Company's Annual
Report on Form 10-K, the Company is exposed to certain contingent liabilities
which, if resolved adversely to the Company, would adversely affect its
liquidity, its results of operations, and/or its financial position.
