ITEM 1 -- BUSINESS

The Company

Data Switch Corporation (referred to as the "Company") designs,
develops, manufactures, markets and services products for large
scale data center networks.  These products include fiber-based
systems, channel networking systems, channel switches and data
communication switches.  The Company's products are intended to
facilitate the flow of data through complex information processing
resources, such as airline reservation systems, financial networks
and common carrier networks.  These products reduce system
downtime, improve performance and increase total equipment
flexibility by switching the flow of data from overloaded or failed
equipment to available equipment.

The Company was incorporated in Delaware in April 1977 and became
a public company on the over-the- counter market in April 1982.  In
December 1986, the Company acquired controlling interest in T-Bar
Incorporated ("T-Bar").  The remaining outstanding shares were
acquired in the third quarter of 1987.  T-Bar was merged into the
Company in January 1990.  The Company continues to manufacture and
sell certain of its products under the T-Bar name and logo.

accounting for 24% of total revenues in 1993.  Fiber-based systems
revenue increased substantially due to the market acceptance of the
Company's Fiber Management System, high density fiber channel
connectors and fiber switch systems.  Channel networking systems
revenue increased slightly, with revenue contribution from early
customer shipments of the Model DDS 9090 offsetting a decline in
channel extenders.  Revenue for the Company's channel switches
declined due primarily to customers' transition to new IBM
fiber-optic-based mainframes and weak international sales.  Data
communications switch revenue was down as a result of competitive
pressures and a modest decline in the market.  T-Bar revenue
increased slightly despite external production problems.
Service revenue increased due to the increased customer base.


Fiber-Based Systems

The newest generation of IBM mainframes is fiber-based.  Data
Switch offers products that facilitate the connectivity and
networking of these new systems.

The Company's Fiber Management System (FMS) consists of
pre-assembled fiber-optic cabling and components, as well as a
planning and installation service for interconnecting these new
data center systems. FMS began shipping in late 1992.  FMS prices
range from $50,000 to $750,000, depending on the size and
complexity of the installation.

Within the data center, a device called a "director" dynamically
networks new mainframes and fiber-based peripheral devices. A
director can re-distribute data traffic and bypass failed
computers, computer channels, or control units, thus enabling
companies to avoid downtime. In early 1993, the Company began
shipping a High-Density Director Array product. The Company
manufactures the Director Array through a reseller agreement for
key technology, and adds other features, such as enhanced
redundancy, increased density packaging and control features.
Prices for the Director Array range from $100,000 to $230,000,
depending on the number of connections required.

The new generation of fiber-based mainframes cannot directly
communicate with older, copper-based mainframes or peripherals.
Protocol converters enable products from the different generations
to work together.  The Company's High-Density FX (HDFX) converter
packages together up to 32 fiber-to-copper protocol systems. The
High-Density MX (HDMX) product converts a multi-mode fiber-optic
signal into a single mode signal.  The High-Density BX (HDBX)
product allows older copper-based channels and devices to operate
over fiber-optic cables and extends their operational range up to
3km. The High-Density CX (HDCX) product extends the repeat
capability of a fiber signal.  The first of these products were

to $275,000, depending on application requirements.

In mid-1993, the Company introduced the Configuration Change
Management System (CCMS), a software support system for
multi-generation data centers.  CCMS builds a data center
configuration database that generates reports and graphical,
logical configurations.  While applicable across many of the
Company's products, CCMS is typically sold with FMS.  The CCMS
central information database complements FMS by generating its own
real-time for use at any point during planning for data center
consolidations, migration and equipment changes.  The CCMS site
license is $25,000.


Channel Networking Systems

The Company's 9090 Distributed Director System (DDS) converts the
mainframe's signals for transmission over high-speed telephone
company lines to connect to other mainframes, high-speed printers,
tape storage units, and workstations at user sites located anywhere
in the world.  DDS enables a company to share resources, provides
alternate paths in case a line fails, and balances traffic over the
lines to optimize performance.  The Company began customer
shipments of DDS in the first half of 1993. The cost of a typical
Model 9090 system with support for a multi-site network is
approximately $250,000.

Channel extenders provide point-to-point connections between a
mainframe and a peripheral.  Historically, the layout of large
computer facilities was restricted by a 200- or 400-foot copper
cable limitation for connecting peripheral equipment to mainframe
computers.  Channel extension overcomes this limitation.  The
Company's current primary channel extension products, the Models
9200 and 9400, were introduced in early 1991 to multiplex several
channels over one or two high-speed communications lines, thereby
providing the customer with greater flexibility and economies than
previous products.  In late 1992, the Company began shipping an
enhanced ChannelPlexer product, which combines eight channels for
transmission over a single communications line.  These systems
range in price from approximately $25,000 to $400,000, depending on
application requirements.


Channel Switches

Channel switches serve in copper-based networks of mainframes and
peripherals.

The Company's Models 2400, 1800 and 1200 route data between
multiple, copper-based mainframe computers and peripheral
equipment. The Model 1800 is the industry's largest switch,
supporting up to 48 computer channels by 96 device ports. These

switches range in price from approximately $25,000 to $2,000,000,
depending on size, sophistication and capacity.

The Model 3600 Single and Redundant Matrix switches, introduced in
early 1992, offer static matrix switching of non-fiber channels,
and integrated fiber-optic switching and conversion, easing the
customer's migration to the newer fiber architecture.  Prices range
from $57,000 to $2,000,000, depending on the modules included.

The HostNet Models 9088 and 9089 dynamically switch as many as 32
computer channels, allowing users to access applications or
information residing on any attached computer.  The Model 9088
provides local connectivity at channel speeds, and the Model 9089
integrates channel extension to provide high-speed interconnection
of computers at different metropolitan sites. These products  range
in price from approximately $60,000 to $2,000,000.

Data Communications Switches

Data communications switching systems maintain connections between
front-end processors attached to a large computer network and
potentially thousands of communications lines connecting remote
network sites.  Typical applications require high availability of
communications lines, such as for travel reservation systems and
banking automated teller machines. The Company's family of
distributed matrix switches includes the Universe, the
Monolith-Plus, and the Remote Monitoring Unit.  These products can
handle communications traffic that ranges in speed from 50 bps to
2.048Mbps. The Universe system handles up to 4,096 ports, and
multiple systems can be combined under common control to provide as
many as 32,000 available ports.  Monolith-Plus is a self-contained
320-port switch that can be upgraded to a satellite cabinet of a
Universe system.  The Remote Monitoring Unit gives users with
communications matrix switches the ability to perform centralized
real-time monitoring of remote site communications lines.  From a
central console, an operator can initiate monitoring of any line
attached to the switch at a remote, unmanned data center.  A
LAN-based network management system provides disaster recovery
capability for network control.  These systems range in price from
approximately $26,000 to $1,500,000, with a typical system price of
$350,000.

T-Bar Products

The Company's T-Bar division develops and markets a variety of
switches and components for voice, video and data applications.
T-Bar's exclusive multi-pole relay is used in military applications
demanding the highest reliability in potentially harsh operating
environments.  These products range in price from $65 to $900.

The Variswitch product provides sparing for critical network
components and systems.  Value-added resellers for mini-computer
systems integrate the Variswitch into their products to address

failsafe applications.  Switching is provided for LANs, voice,
fiber-optics and data channels in addition to all standard data
communications interfaces.  The Variswitch ranges in price from
$5,000 to $300,000.

T-Bar offers switching, monitoring and cable management products
for the fiber-optic market.  T-Bar's Optiswitch product is a
photonic matrix switch transparent to speed and protocol.  The
Optiswitch product is typically priced from $15,000 to $162,000.

T-Bar expanded into the LAN management market with the announcement
of LANtap in August 1993.  LANtap reduces the expense of managing
large LAN networks by sharing expensive diagnostic equipment and
facilitating centralized remote testing.  The Company will begin
shipment of this product in the first quarter of 1994.


Sales and Marketing; Foreign Sales; and Backlog

The Company's customers are large companies with IBM and
IBM-compatible mainframe computers and related peripheral devices.
Typical customers include airlines, telecommunications companies,
manufacturing firms, power utilities, insurance companies, banks
and securities firms.

The Company has a worldwide sales force of 76 sales managers,
representatives and systems engineers, located in 26 offices
throughout the United States and overseas.  Products are sold
internationally through wholly-owned subsidiaries in Canada, the
United Kingdom, Germany, and Italy, and through independent
distributors worldwide.

The Company does not emphasize financing as part of its sales and
marketing efforts.  The Company maintains a leasing arrangement for
customers who elect lease financing.  Sales-type leases accounted
for approximately 2% of the Company's annual sales in 1993 and 8%
in 1992.  The equipment leases generally range from two to five
years and include an option to purchase the equipment at the end of
the lease term.

The Company generally sells its equipment with a 90-day warranty
covering both parts and labor.  The Company also provides
installation and maintenance services for its products.  As of
February 1, 1994, the Company had 97 service personnel located in
26 offices in the United States and overseas.  The Company also
provides service to certain of its customers through third-party
arrangements.

For the year ended December 31, 1993, the Company's sales to
customers in foreign countries were approximately $17,000,000,
representing approximately 18% of sales compared to $19,800,000, or
24% of sales, in 1992 and $28,100,000, or 27% of sales, in 1991,
reflecting a decrease in sales in all foreign markets from 1992 to

1993 and the severe adverse impact of European economic conditions
from 1991 to 1992.  In 1993, the company established a direct sales
subsidiary in Italy and signed reseller agreements with IBM Japan
and Hitachi Data Systems.  The Company expects to increase its
market presence in foreign countries in 1994.

All product orders are generally cancelable without penalty to the
customer.  Substantially all of the Company's backlog is shipped
within 90 days.  Backlog at any particular date depends on the
timing of orders, and therefore is not necessarily a reliable
indicator of future sales over an extended period of time.  The
Company did not experience a material amount of order cancellations
in 1993 or 1992.  The Company's backlog was approximately
$7,781,000 at December 31, 1993, compared with approximately
$12,003,000 at December 31, 1992.

During 1992 Data Switch received two multi-million dollar,
multi-year contracts from the Federal Reserve and Harris
Corporation.  The Federal Reserve's contract with the Company is
for communication switches and control systems for its network
modernization program.  Harris Corporation's contract with the
Company is for communications switching equipment for its project
to modernize the nation's air traffic control system.  During 1993
the Federal Reserve and Harris Corporation purchased $2.2 million
and $1.1 million, respectively, of goods related to these
contracts.  These contracts are subject to change and are thus not
included in the backlog.  However, it is anticipated that future
releases under these contracts will amount to $2.8 million and $2.0
million for the Federal Reserve and Harris Corporation,
respectively.


Engineering and Development

The industry in which the Company operates is subject to rapid
technological change.  The Company is committed to the development
of new products and the application of new technologies to existing
products.  Engineering and development activities resulted in
expenditures of $12,970,000, $12,725,000 and $11,733,000 for the
years ended December 31, 1993, 1992 and 1991, respectively. 
Engineering and development expenditures are expensed as incurred.
The Company anticipates engineering and development expenditures of
approximately $12,000,000 in 1994.


Manufacturing

Manufacturing operations consist of the assembly and testing of
equipment.  Some assemblies are fabricated from purchased
components, and other subsystems are manufactured and assembled by
third parties.  All components and assembled equipment undergo
rigorous quality-control testing as part of the manufacturing
process.  Components and subassemblies are generally available from

more than one source.  The Company has not experienced any
significant difficulties or delays in securing components.


Competition

The marketing for data center networking equipment is intensely
competitive.  Competition is based on technology, equipment
features, quality, availability, price and service.  The Company
believes that it is competitive in all of these areas.

In the fiber-based systems market, the Company primarily competes
with IBM and regional cabling companies.  Conversion products are
sold by Comparex, IBM, Fibercom, McData and other companies.  While
IBM holds the dominant market share, it does not offer a
high-density product with enhanced redundancy features, which the
Company does.  In addition, the IBM-compatible mainframe
manufacturers do not make protocol conversion products.  Data
Switch competes with IBM and a small number of resellers in the
director market.

In the field of channel networking and channel extension, the
Company competes with Computer Network Technology and Network
Systems Corporation.  A number of other companies also manufacture
and market channel extension products.

In the channel switching market, the Company traditionally sold
against IBM.  The Company believes that IBM no longer actively
markets switching systems that support its older-architecture
mainframes because IBM is emphasizing its new fiber-based systems.

Principal competitors in the data communications switching market
include Telenex (a division of General Signal), Bytex, which was
acquired by Network Systems in mid-1993 and Dynatech.

T-Bar primarily competes with Hadax Electronics and Telenex.


Employees

As of February 1, 1994, the Company had a total of 479 employees,
including 9 officers, 59 administrative personnel, 219 sales,
service and marketing personnel, 85 engineering personnel and 107
production personnel.  None of the Company's employees is
represented by a labor organization, and the Company considers its
relationship with its employees to be good.

Patents and Trademarks

The Company has registered the name "DATA SWITCH".  The Company
also acquired certain patents and trademarks in connection with its
acquisition of T-Bar, including the trademark "T-BAR".  The Company
believes that although its patents and trademarks have value, they

are not material to its businesses, either individually or in the
aggregate.


ITEM 2 -- PROPERTIES

The Company currently leases a 59,000-square-foot facility in
Shelton, Connecticut, for its executive, administrative, sales and
engineering offices.  The lease has a current annual rent of

$1,021,000 and expires in 2005, with a no-cost cancellation option
in mid-1995.  The Company leases production facilities and office
space of approximately 64,000 square feet in Orange, Connecticut,
under a lease expiring June 30, 1995, with a two and one-half year
renewal option.  Annual rental in 1994 will be approximately
$308,000.  The Company also leases approximately 23,000 square feet
in Milford, Connecticut which was formerly used for manufacturing
purposes at an annual rental of $156,000 under a lease expiring
June 30, 1997, with a renewal option through June 30, 2002.  The
Company has sublet approximately 7,300 square feet of this facility
at an annual rental income of $36,000.  The Company is currently
using the remainder of such space as a warehouse facility, but is
attempting to sublet such space.  The Company believes that the
current facilities are adequate for anticipated operating
requirements.

The Company leases sales or service office space in 27 cities in
the United States, Canada and Europe.  The leases have varying
expirations through March 2013, and the aggregate annual rent is
currently approximately $1,118,000.

ITEM 3 -- LEGAL PROCEEDINGS

A former officer of the Company who sued the Company for breach of
an alleged promise of lifetime employment was awarded a jury
verdict of $413,000 in October 1991.  In May 1993, the court
granted the Company's motion to set aside the verdict.  Such former
officer has appealed the court's decision.  The Company believes
that it has meritorious grounds on which to defend such appeal.

ITEM 4 -- SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

None.

ITEM 7 --      MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
               CONDITION AND RESULTS OF OPERATIONS

Results of Operations

1993 vs 1992

The Company's product revenues increased in 1993 due to the
shipment of new products.  Product revenues increased 14.1%
compared with 1992, reversing a trend of declining revenues from
1990 to 1992.  Revenues in 1994 are expected to be stable or
increase slightly as new product revenues continue to increase
while established product lines decline.  However, it is difficult
to predict with certainty the speed of transition from the older
copper-based technology to the newer fiber-based products.  Service
revenues increased 9.6% from 1992, due to an increase in the
installed base, but are not expected to increase significantly in
1994.  Revenues in Europe declined from $13,096,000 in 1992 to
$12,254,000 in 1993 due to continued weak economic conditions and
as a result the European operations reported a loss of $504,000 in
1993.  The Company does not expect a decline to continue in the
European market due to anticipated results from its new Italian
subsidiary coupled with steps taken to strengthen the European
organization.  The Company reported a net loss of $1,993,000 in
1993 compared with a net loss of $1,013,000 in 1992.  The net loss
in 1993 included a one-time pre-tax restructuring charge of
$1,780,000 for employee severance and related expenses as the
Company reduced its staffing levels approximately 10% to structure
the Company to operate profitably at current revenue levels.  The
accrued costs of this restructuring will be expended by the end of
1994.  The future reduction in annual employee costs is anticipated
to be approximately $3,000,000.

Cost of product revenues increased in 1993 to 56.3% from 46.7% in
1992.  Cost of service revenues declined to 64.2% in 1993 from
66.1% in 1992.  The increase in cost of product revenues resulted
primarily from  product mix, including a significant increase in


sales by the Company of products manufactured by third parties,
which products have lower gross margins than those manufactured by
the Company.  The Company also experienced a decline in margins due
to discounts on large dollar sales.  The Company believes that in
1994 the cost of product revenues will be similar to such costs in
1993.

The Company reduced operating expenses in 1993, including a
$1,711,000 reduction in selling, general and administrative
expenses.  This decrease was achieved through the consolidation of
facilities in 1993, and a smaller average workforce in 1993 versus
1992.  As a result of these savings and increased revenues in 1993,
selling, general and administrative expenses as a percentage of
revenue decreased to 26.3% in 1993 compared with 31.8% in 1992.

Engineering and development expenditures increased to $12,970,000
in 1993 from $12,725,000 in 1992, comprising 13.6% and 15.1% of
revenues in 1993 and 1992, respectively.  These expenditures
supported development of strategic new products which began
shipping in 1993.  The Company anticipates spending approximately
$12,000,000 in engineering and development in 1994.

Although long and short-term debt outstanding was $5,195,000 more
(including capital lease obligations) at December 31, 1993 than at
December 31, 1992, interest expense was substantially less in 1993
versus 1992 because the average outstanding debt and interest rates
were lower in 1993 than 1992.

The Company recorded an income tax benefit in 1993 primarily as a
result of the reversal of temporary differences on which the
Company had previously provided  deferred taxes.  The tax benefit
in amount and percentage was lower in 1993 than in 1992, as a
result of limitations on the ability to recognize the tax benefit
of both domestic and foreign subsidiary losses.  The Company
adopted SFAS No. 109, Accounting for Income Taxes in 1993.  The net
effect of adoption of the statement was not material to the
consolidated results of operations or financial position of the
Company.

In November 1992 the Financial Accounting Standards Board issued
SFAS No. 112 Employers' Accounting for Post Employment Benefits
effective for fiscal years beginning after December 15, 1993.
Under this statement employers are required to recognize the
obligation to provide post employment benefits if the obligation is
attributable to employee services already rendered, employee rights
to those benefits accumulate or vest, payment of the benefits is
probable, and the amount of benefits can be reasonably estimated.
The Company believes that the net effect of adoption of the
statement will not be material to the consolidated results of
operations or financial position of the Company.





1992 vs 1991

The Company's revenues declined in 1992 due to a continued weak
economy both domestically and in major foreign markets.  Also
revenue anticipated from new product sales was not attained due to
a delay in shipment of new products.  Due to late release of new
products, shipment of these products did not begin until the first
quarter of 1993, delaying revenue recognition until the second
quarter of 1993.  Service revenues increased 4.8% compared with
1991, while product revenues decreased 23.0% from 1991.  Revenues
in Europe declined from $18,208,000 in 1991 to $13,096,000 in 1992
due to weakened economic conditions in that area and as a result
the European operations reported a loss of $372,000 in 1992.
The Company reported a net loss of $1,013,000 in 1992 compared with
a net loss of $32,423,000 in 1991.  The net loss in
1991 included a goodwill write-down of $32,996,000 and an
extraordinary gain of $425,000.

Cost of product revenues increased slightly in 1992 to 46.7% from
45.9% in 1991.  Cost of service revenues declined significantly to
66.1% in 1992 from 74.7% in 1991.  The reduction in cost of service
revenues resulted from a revenue increase of $816,000, generated
from the increased installed base, while costs decreased $911,000
as the Company reduced service overhead expenditures.

The Company reduced operational expenses substantially in 1992,
including a $6,122,000 reduction in selling, general and
administrative expenses.  This decrease in expenses was achieved
primarily through a workforce reduction of approximately 18%.  As
a result of these savings, although revenues declined 18.4% in
1992, selling, general and administrative expenses as a percentage
of revenue did not increase, remaining at 31.8% in 1992 compared
with 31.9% in 1991.

The significant reduction in selling, general and administrative
costs allowed the Company to redirect some of these savings to
product development.  Engineering and development expenditures
increased to $12,725,000 in 1992 from $11,733,000 in 1991,
comprising 15.1% and 11.4% of revenues in 1992 and 1991,
respectively.  These expenditures supported development of
strategic new products that began shipment in 1993.

In the third quarter of 1991 the Company wrote down goodwill
associated with the  purchase of T-Bar, to estimated recoverable
value of approximately $2.4 million, and wrote off goodwill
associated with the purchase of the minority interest in IntelliNet
Corporation.  This write-down, which amounted to $32,996,000,
resulted from the assessment of the data communications product
line and the IntelliNet product which is sold in conjunction with
the Company's data communications products.  T-Bar was acquired in
1986 and had three primary product lines:  (i)  a data processing
switch which was less technologically advanced than that of Data
Switch;  (ii) a data communication matrix switch that was


substantially ahead of Data Switch's product offering; and (iii)
a range of small switches and components which was a declining and
relatively small product line.  The Company's intention at the time
of the acquisition was to emphasize the product strengths of each
company, that is, the T-Bar data communication matrix switch and
the Data Switch data processing switch.

This strategy was followed with some success and these product line
revenues grew through 1988, but the data communication revenues
began to decline in 1989.  During this period the Company invested
heavily in the next generation data communication switch which was
introduced in 1990.  Initial market acceptance of the new Universe
switch produced an increase in revenues in the second half of 1990
and the expectation for continued profitability in the data
communication line was high.  However, this anticipated growth was
not sustained and the first half of 1991 reflected a 25% decline
versus second half of 1990.

In addition to these trends, in September 1991 IBM made significant
product announcements that caused many competitors in the industry,
including the Company, to re-examine its long-term strategy.  These
announcements made it clear that there was to be an imminent range
of products used in the mainframe environment for which the Company
had no products that could compete with the IBM Escon product line.

Also, the demand for the Company's existing data processing
switches would be negatively impacted by the new architecture.
Management determined that failure to respond to the change in
market condition caused by the introduction of the IBM Escon
architecture would have resulted in a major continuing
deterioration in the Company's operating results within a two to
three year time-frame.  As a result the Company decided to put the
majority of its development emphasis on the data processing product
line.  The Company believes these factors resulted in an impairment
to the value of the goodwill, and it wrote down goodwill to its
estimated recoverable value.

Interest expense declined significantly as a result of reduced debt
levels achieved through positive cash flow in 1992.

The Company recorded an income tax benefit in 1992 primarily as a
result of foreign subsidiary losses, which can be carried-back to
offset taxes in prior profitable years.  The effective tax rate,
excluding goodwill amortization and write-down from pre-tax income,
was lower in 1992 than in 1991, as a result of domestic losses for
which no income tax benefit was recognized in 1992.

Liquidity and Capital Resources

The Company used $7,258,000 of cash before financing activities in
1993, compared to generating $12,880,000 in 1992.  As of December
31, 1993 the Company had working capital of $34,350,000 reflecting
an increase of $6,564,000 from the prior year.  The cash used


before financing activities and this increase in working capital
was primarily a result of the increase in accounts receivable
during the year, which was generated from increased revenues in
1993.  In addition to selling its products, the Company also leases
its products under sales-type lease agreements.  These lease
receivables are available for sale as a source of financing.  The
Company received approximately $3,043,000 in 1993 from the sale of
leases.

The ratio of current assets to current liabilities was 3.6:1 at
year-end 1993 compared to 3.0:1 at year-end 1992.

Long-term debt consisted of $19,515,000 of convertible subordinated
debentures and $5,972,000 of indebtedness under a revolving line of
credit of $8,000,000 with People's Bank all of which was available
based on a formula of eligible receivables (as defined).  This line
of credit is collateralized by a first lien on substantially all of
the Company's assets, and is available, subject to maintenance of
certain covenants and financial ratios, through March 1, 1996.  At
December 31, 1993 the Company was not in compliance with a
financial covenant contained in its credit agreement; however the
Company has obtained a waiver of this covenant for 1993.
There are no significant capital expenditures planned for 1994; the
aggregate amount of spending is anticipated to be close to the
level of depreciation for the year.

In the opinion of management, existing financial resources,
including cash anticipated to be generated by operations and
available under existing credit facilities, will be adequate to
meet current and expected operating and capital requirements.


Impact of Inflation

Inflation did not have a significant impact on the Company during
1991, 1992 and 1993, and is not expected to do so in 1994.

                 REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To the Board of Directors of
Data Switch Corporation

We have audited the consolidated financial statements and the
financial statement schedules of Data Switch Corporation listed in
the index of consolidated financial statements and schedules in
Item 8 of this Form 10-K.  These financial statements and financial
statement schedules are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these
financial statements and financial statement schedules based on our
audits.

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

In our opinion, the financial statements referred to above present
fairly, in all material respects, the consolidated financial
position of Data Switch Corporation at December 31, 1993 and 1992,
and the consolidated results of their operations and their cash
flows for each of the three years in the period ended December 31,
1993, in conformity with generally accepted accounting principles.
In addition, in our opinion, the financial statement schedules
referred to above, when considered in relation to the basic
financial statements taken as a whole, present fairly, in all
material respects, the information required to be included therein.

                        DATA SWITCH CORPORATION

                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.       Summary of Significant Accounting Policies

         Principles of Consolidation:

         The consolidated financial statements include the accounts
         of Data Switch Corporation and its subsidiaries (the
         "Company").  All intercompany transactions and balances
         are eliminated.

         Inventories:

         Inventories are stated at the lower of cost, which
         approximates a first-in, first-out basis, or market.



         Property and Equipment:

         Property and equipment are stated at cost and depreciated
         using the straight-line method over estimated useful lives
         of two to ten years or, in the case of leasehold
         improvements, over the term of the lease, if shorter.
         The cost and accumulated depreciation applicable to assets
         retired are removed from the accounts and the gain or loss
         on disposition is charged to income.

         Goodwill:

         The excess of cost over the fair value of net assets
         acquired in ChannelNet minority interest acquisitions
         is being amortized using the straight-line method
         over 10 years.  The excess of cost over the fair value
         of net assets acquired in T-Bar and IntelliNet purchases
         had been amortized using the straight-line method over
         periods of 10 to 25 years.  The Company assesses the
         recoverability of goodwill on acquired lines of business
         by determining whether amortization of goodwill over its
         original estimated useful life can be recovered through
         estimated future undiscounted operating income, excluding
         goodwill amortization.  (See Note 4.)

         Deferred Debt Issuance Costs:

         Included in other assets in 1993 and 1992 are deferred
         debt issuance costs.  These costs are being amortized over
         the term of the debt and are being included in the
         determination of any gain or loss realized as debt is
         retired.

         Revenue Recognition:

         The Company recognizes revenues from system sales and
         sales-type leases when risk of loss transfers to the
         customer, generally when the equipment is shipped.  On new
         products or substantial modifications to existing
         products, revenue is deferred until customer acceptance.
         Unearned finance income on sales-type  leases is
         recognized over the lease term.  Service revenues are
         recognized over the contractual period for maintenance
         contracts, or as services are performed.  Rental income on
         systems leased to customers under operating leases is
         recorded monthly, as earned.

         Warranty:

         It is the Company's general policy to give 90 day
         warranties on its product sales.  Estimated warranty
         expense is accrued in cost of sales in connection with
         product sales.


         Income Taxes:

         In 1991 and 1992, the Company used the liability method of
         accounting for income taxes.  In 1993, the Company adopted
         Statement of Financial Accounting Standards No. 109,
         Accounting for Income Taxes (SFAS No. 109), effective
         January 1, 1993.  The cumulative effect of the change in
         accounting principle as of January 1, 1993 was not
         material to the consolidated results of operations or
         financial position of the Company.

         Foreign Currency Translation:

         The Company recognizes the local currency of its European
         subsidiaries as their functional currency and accordingly,
         translates assets and liabilities at year-end exchange
         rates and revenue and expense items at average exchange
         rates prevailing during the year.  The resulting
         translation adjustments are recorded as a separate
         component of shareholders' equity.

         Cash Flows:

         The Company considers all highly liquid debt instruments
         purchased with a maturity of three months or less to be
         cash equivalents.

         Earnings Per Share:

         Primary earnings per share is computed on the basis of the
         weighted average number of shares outstanding plus the
         common stock equivalents that would arise from the
         exercise of stock options and stock warrants, where not
         anti-dilutive.

         Fully diluted earnings per share is computed on the basis
         of the weighted average number of shares outstanding plus
         the common stock equivalents that would arise from the
         exercise of stock options and stock warrants, where not
         anti-dilutive, plus the effect of the additional shares
         arising from the conversion of the convertible
         subordinated debentures.

4.       Goodwill

         In the third quarter of 1991 the Company wrote down
         goodwill associated with the purchase of T-Bar to
         estimated recoverable value of approximately $2.4 million,
         and wrote off goodwill associated with the purchase of the
         minority interest in IntelliNet Corporation.  This
         write-down, which amounted to $32,996,000, resulted from
         the assessment of the data communications product line and



         the IntelliNet product which is sold in conjunction with
         the Company's data communications products.

         To the extent that T-Bar pre-acquisition net operating
         loss carryforwards and tax credit carryforwards are
         utilized, the Company recognizes income tax expense and
         reduces goodwill rather than recognizing a tax benefit.
         Goodwill consisted of the following at December 31, 1993
         and 1992:

<FN>
(a)      As of December 31, 1992, the Company had an agreement with
         Chemical Bank and Marine Midland Bank, N.A., providing for
         borrowings of up to $11,400,000.  This agreement matured
         on March 13, 1993.  On March 11, 1993, the Company entered
         into a new long-term credit agreement with People's Bank
         providing for domestic borrowings of up to $8,000,000, all
         of which was available at December 31, 1993, based on a


         formula of eligible receivables (as defined).  The credit
         facility is collateralized by a first lien on
         substantially all of the Company's assets, and the
         agreement contains, among other provisions and covenants,
         the following: (1) subordination of all existing and
         future indebtedness (as defined) of the Company to the
         indebtedness under the credit facility; (2) limitations on
         dividend payments, stock purchases and subordinated debt
         repurchases; (3) maintenance of levels of Consolidated
         Adjusted Tangible Net Worth (as defined) and (4)
         achievement of various financial ratios.  At December 31,
         1993 the Company was not in compliance with a financial
         covenant contained in its credit agreement; however, the
         Company has obtained a waiver of this covenant for 1993.
         The Company is required to pay a commitment fee equal to
         1% of the unused borrowings under the line of credit.  The
         loans mature on March 1, 1996, and bear interest at the
         People's prime rate plus 1 1/4%.

(b)      The 9% convertible subordinated debentures are convertible
         into the Company's common stock at a price of $6.92 per
         share. These debentures, due in 1996, are redeemable at a
         premium of 4% decreasing to par in 1995, in whole or in
         part, at the option of the Company.

(c)      The 8-1/4% convertible subordinated debentures, which
         mature on June 1, 2002, are convertible into the
         Company's common stock at $6.92 per share and are
         redeemable in whole or in part, at the option of the
         Company.  The Company is required to redeem on June 1,
         1998, and on each June 1 thereafter through 2001,
         $7,000,000 aggregate principal amount of debentures at a
         redemption price of 100% of principal amount together with
         interest accrued to the redemption date, calculated to
         retire 80% of the debentures prior to maturity.  As of
         December 31, 1993 $19,024,000 or 54.4% of the original
         amount had been purchased or exchanged, which satisfies
         the repurchase requirements of the Company for 1998 and
         1999.  This agreement contains, among other provisions and
         covenants, the following:  (1) prepayment options at
         a premium of 4.95% decreasing to par in 1997; (2)
         subordination of the debentures to all existing and future
         indebtedness (as defined); (3) restrictions on the payment
         of dividends and stock purchases and (4) maintenance of
         levels of Consolidated Tangible Net Worth (as defined).

(d)      During the first quarter of 1990, the Company concluded an
         exchange offer to replace each $1,000 principal amount of
         existing 8-1/4% convertible subordinated debentures with
         a new $700 principal amount of 15% senior subordinated
         notes due February 1, 2000 ("New Notes"), plus 56 warrants
         ("1995 Warrants," See Note 10).



         Pursuant to the terms of the indenture in connection with
         the New Notes, as a result of the goodwill write-
         down (See Note 4), the Company was obligated to offer to
         repurchase the balance of the outstanding New Notes, at a
         purchase price equal to the principal amount of New Notes
         tendered for payment, plus accrued interest.  As a result,
         $1,141,000 of New Notes were repurchased in 1992.  As of
         December 31, 1992, $91,000 principal amount of New Notes
         were outstanding and were classified as short term.  In
         March 1993 the Company redeemed the balance of the
         remaining New Notes at a purchase price equal to 107% of
         the principal amount, plus accrued interest through March
         31, 1993.

(e)      In 1991 the Company repurchased 8-1/4% convertible
         subordinated debentures and 15% New Notes on the
         open market.  These transactions resulted in extraordinary
         gains in 1991.

(f)      In May 1990 the Company entered into an installment loan
         agreement with Chase Manhattan Service Corporation under
         which the Company received $462,000.  This note was
         collateralized by certain assets of the Company and was
         repaid in monthly installments over three years at an
         interest rate of 12%.  The final payment was made in May
         1993.

10.      Common Stock

         Each 1995 Warrant issued pursuant to the debenture
         exchange offer in 1990 entitles the holder to purchase
         one share of common stock at a price of $5.00 per share,
         subject to adjustment, from January 1, 1991 through
         December 31, 1995.  The expiration date is subject to
         extension under certain circumstances.  The 1995 Warrants,
         which had a fair value of $0.75 per 1995 Warrant at the
         date of the exchange, are redeemable at the option of the
         holder for $1.25 during the last quarter of 1994.  There
         were no 1995 Warrants exercised in 1993 or 1992.  As of
         December 31, 1993, 758,184 of the 1995 Warrants were
         outstanding.

         The Company agreed in July 1992 to issue warrants to an
         investment banking firm for services rendered, pursuant to
         which such investment bank may, at any time after August
         1, 1993 and prior to July 31, 1997, purchase 100,000
         shares of the Company's common stock at $2.38 per share.

         The Company has reserved, as of December 31, 1993,
         3,678,271 shares to be issued upon conversion of the
         8-1/4% convertible subordinated debentures, the 9%
         convertible subordinated debentures, the 1995 Warrants and
         the investment banking warrants.


         In 1988, the Company declared a dividend of common share
         purchase rights in the amount of one right for each 10
         shares of the Company's common stock.  The rights are
         attached to and trade with the shares of common stock, and
         each right entitles the holder to acquire one additional
         share of common stock at a price of $16.00 per share,
         subject to adjustment.  In the event of any merger or
         other combination of the Company not submitted to a vote
         of the shareholders, the rights, along with the exercise
         price, are  exchangeable into 4 shares of the voting stock
         of the Company or its successor or survivor (but the
         then-market value of such shares shall not exceed 4 times
         the exercise price of the rights). The rights are
         redeemable by the Company for $.01 per right at any time
         prior to the occurrence of certain events constituting
         change of control or intention to effect a change of
         control of the Company.

11.      Employee Incentive Plans

         Stock Options:

         The Company has one incentive stock option plan ("ISOP")
         and one non-qualified stock option plan ("NQSOP") under
         which stock options may be granted to employees to
         purchase the Company's common stock at a price not less
         than fair market value at date of grant.  Options are
         granted for a term of 10 years under the ISOP, and are
         serially exercisable at the rate of 33% per annum
         commencing 18 months after the date of grant.

         Options under the 1988 NQSOP are granted for a term of
         five years.  The plan provides for the same calculation of
         exercise price as under the ISOP, but permits option
         grants to employees, outside directors, advisors, and
         consultants who are not full-time employees  of the
         Company, and permits flexible exercise terms, except as to
         outside directors. All outside director option grants
         under the NQSOP are fixed at 10,000 shares (but not more
         than an aggregate exercise price of $100,000) on such
         person's election to the Board of Directors, with an
         additional option grant of 5,000 shares to be awarded
         after each anniversary of service.  All outside director
         options are exercisable as follows:  one-third of the
         shares after the first anniversary date of grant,
         two-thirds of the shares after the second anniversary, and
         all of the shares after the third anniversary.







The changes in the number of common shares issuable under
outstanding options, the number of shares reserved
for issuance, and the price range of options are as follows:

</TABLE>


         Stock Purchase Plan:

         The 1981 Stock Purchase Plan provided directors, officers
         and managers of the Company the opportunity to purchase
         the Company's common stock.  The total number of shares
         authorized under the plan cannot exceed 375,000.  The
         purchase price of the stock cannot be less than fair
         market value of the stock on the date of purchase.  In
         accordance with the terms of the plan, the Company has
         taken notes, for 90% of the purchase price, for certain
         purchases under the plan.  These notes, which are shown as
         a reduction of shareholders' equity, totalled $24,000 at
         December 31, 1993 and $78,000 at both December 31, 1992
         and 1991.  Notes are due 10 years from the date of the
         note and bear interest at rates of 6% or 9%, payable
         annually.  The plan expired with respect to future
         purchases on January 4, 1983.

         The 1991 Employee Stock Purchase Plan, which succeeded a
         similar prior plan, grants to all regular full-time
         employees of the Company and its subsidiaries the right to
         purchase up to an aggregate of 500,000 shares of the
         Company's stock through payroll deductions, at a purchase
         price equal to 85% of the fair market value of the
         shares during each quarterly period that the plan is in
         effect.  During 1993, 1992 and 1991, employees purchased
         121,997, 153,401 and 127,055 shares, respectively, of the
         Company's stock through this non-compensatory plan
         and its predecessor.  As of December 31, 1993, there were
         150,738 shares reserved for future issuance under this
         Plan.

         Stock Bonus Plan:

         Under the 1983 Stock Bonus Plan, 150,000 shares were
         reserved for issuance.  The Board of Directors awarded
         9,810, 8,550 and 12,775 shares to employees during 1993,
         1992 and 1991, respectively.  Such awards are charged
         to expense and valued at the fair market value of the
         stock at the date awarded.  As of December 31, 1993, there
         were 10,541 shares reserved for future issuance under this
         plan.

         Data Switch Bonus Plan:

         Under the Data Switch Bonus Plan ("Bonus Plan"), up to 10%
         of the Company's pre-tax, pre-bonus profit is placed
         into a pool to make cash awards to officers and other key
         employees based on base salary and grade level.  This
         plan, adopted as of July 1, 1992, replaced the 1992
         Executive Bonus Compensation Plan.  Prior to January 1,
         1994, payments under the Bonus Plan were made quarterly,
         based upon quarterly results.  The Bonus Plan was


         amended effective January 1, 1994 to provide for annual
         payments, based upon annual results.  Compensation
         expense under these plans was $173,000, $96,000, and $0 in
         1993, 1992 and 1991, respectively.  The Bonus Plan
         is administered by the Compensation and Stock Option
         Committee of the Board of Directors.

         In 1992, the shareholders approved the 1992 Executive
         Stock Incentive Plan, which is designed to provide
         incentive to a limited number of key executive employees
         of the Company.  Under this plan, 500,000 shares of
         the Company's common stock were reserved for issuance.  On
         an annual basis, up to 6% of the pre-tax, pre-bonus,
         pre-incentive profits of the Company are placed in a bonus
         pool.  Of that pool, 83.3% will be paid in shares and the
         balance in cash, based upon the participant's base salary.
         The shares issued pursuant to this plan are restricted as
         to transfer by the recipient for a period of 2 years.
         There were no cash or stock payments made under this plan
         in 1993 or 1992.

12.      Retirement Savings Plan

         In August 1986, the Board of Directors adopted the
         Retirement Savings Plan ("Savings Plan") for the benefit
         of all full-time employees, effective as of January 1,
         1987.  The Savings Plan is a defined contribution plan.
         The Company's contribution to the Savings Plan was
         $395,000, $344,000 and $367,000 in 1993, 1992 and 1991,
         respectively.

13.      Income Taxes:

         The components of the provision (benefit) for income
         taxes, excluding the tax provision of $291,000 allocated
         to extraordinary gain in 1991 are as follows:

</TABLE>

         At December 31, 1993 the Company had net operating loss
         carryforwards of approximately $2,909,000 for financial
         accounting purposes, of which $1,042,000 resulted from the
         acquisition of T-Bar, $2,252,000 for federal income tax
         purposes and $2,465,000 for alternative minimum tax
         purposes, which if not utilized, will expire in 2000
         through 2001.  The tax net operating loss carryforwards


         are less than the net operating loss carryforwards for
         financial reporting purposes, due to the temporary
         differences noted above.

         The Company has investment and research and development
         tax credits of $3,752,000 for both financial reporting and
         federal income tax purposes, which will expire between
         1996 and 2001.  Included in these amounts are T-Bar
         preacquisition credits of $1,494,000, which will expire
         between 1998 and 2001.

         At December 31, 1993, the Company had unused alternative
         minimum tax credits of $606,000 for financial reporting
         and federal income tax purposes, which can be carried
         forward indefinitely to offset future regular taxes
         payable.

         The cumulative amounts of income of the foreign
         subsidiaries for which no U.S. federal deferred income tax
         liabilities have been recorded were $965,000 and
         $1,502,000 at December 31, 1993 and 1992, respectively.
         The Company intends to reinvest undistributed earnings of
         its foreign subsidiaries and thereby indefinitely postpone
         their remittance.  Such earnings would become taxable upon
         the sale or liquidation of these international
         subsidiaries or upon the remittance of dividends.  It is
         not practicable to estimate the amount of the deferred tax
         liability on such earnings.  Upon remittance, certain
         foreign countries impose withholding taxes that are then
         available, subject to certain limitations, for use as
         credits against the Company's U.S. tax liability, if any.
         The amount of withholding tax that would be payable upon
         remittance of the entire amount of undistributed earnings
         would approximate $161,000.

         telecommunication companies, manufacturing firms, power
         utilities, insurance companies, banks and securities
         firms.  The Company performs ongoing credit evaluations
         of its customers' financial condition and requires no
         collateral from its customers.  There were no sales to
         major customers in excess of 10% of consolidated revenues
         for 1993 or 1992.  At December 31, 1993, one customer
         accounted for approximately 19.0% of the Company's
         consolidated accounts receivable balance.  The Company
         believes it did not have a significant concentration of
         credit risk at December 31, 1992.

         revenue levels.  The accrued cost of this restructuring
         will be expended by the end of 1994.  The future reduction
         in annual employee costs is anticipated to be
         approximately $3,000,000.

16.      Minority Interest Acquisitions

         In January 1990, the Company acquired approximately 10% of
         the ChannelNet common stock for a total value of $820,000.

         In August 1991, the Company purchased the remaining
         outstanding shares of ChannelNet for $701,000 and
         ChannelNet was merged with and into the Company.

17.      Contingencies

         A former officer of the Company who sued the Company for
         breach of an alleged promise of lifetime employment was
         awarded a jury verdict of $413,000 in October 1991.  In
         May 1993, the court granted the Company's motion to set
         aside the verdict.  Such former officer has appealed the
         court's decision.  The Company believes that it has
         meritorious grounds on which to defend such appeal and
         that the ultimate resolution of this matter will not have
         a significant effect upon the consolidated results of
         operations or financial position of the Company.

                      LIFKA EMPLOYMENT AGREEMENT

     This AGREEMENT made as of this 15th day of December, 1993 and
between Data Switch Corporation, a Delaware corporation with
offices at One Enterprise Drive, Shelton, Connecticut  06484 (the
"Company") and William J. Lifka, an individual residing at 610 N.
Flagship Drive, Salem, SC 29676 ("Lifka" or the "Executive").

                         W I T N E S S E T H:

     WHEREAS, the Company desires to retain Lifka to serve as
President and Chief Executive Officer, and Lifka is willing to so
serve on the terms and subject to the conditions
hereof.

     NOW, THEREFORE, in consideration of the mutual covenants
hereinafter set forth, the parties hereto agree as follows:

     1.  Term:  The term of Lifka's employment under this Agreement
(the "Term") shall begin as of December 16, 1993 and continue until
June 15, 1995, unless sooner terminated by Lifka or the Company in
accordance with the terms hereof, or extended by the mutual
agreement of the parties in writing.

     2.  Duties:  Lifka hereby agrees to devote substantially his
full business time and best efforts to his position as President
and Chief Executive Officer of the Company during the Term of this
Agreement, and to perform such other senior executive duties
appropriate to the office of the President, as may be assigned to
him from time to time by the Board of Directors of the Company.

     3.  Base Compensation, Fringes, and Bonus Participation:

         (a)  The Company shall pay to Lifka, and Lifka shall
accept as his base compensation for all services rendered and to be
rendered hereunder, the amounts set forth on the Schedule of Base
Compensation attached as Schedule A hereto, said base compensation
to be payable according to the Company's standard payroll policies.

         (b)  Lifka will also be entitled to participate, in
accordance with the provisions of any applicable plans and
programs, in all life and health insurance and other fringe benefit

programs, plans and arrangements, whether now existing or hereafter
instituted, available to senior executives of the Company. 
Notwithstanding the foregoing, Lifka shall not be eligible for any
bonus or other incentive compensation programs.

     4.  Restricted Stock:   In lieu of the receipt of any stock
options and/or participation in Company bonus plans, the Company
has awarded to Lifka, and Lifka has accepted, a restricted stock
award grant in the amount of 50,000 shares of Data Switch Common
Stock (the "Shares").  Said Shares are being awarded to Executive
for full service during the term of this Agreement, including the
Executive's conducting to completion, to the reasonable
satisfaction of the Board, the search for a successor President and
Chief Executive Officer.  The Executive understands that the Shares
being transferred to him hereunder have not been registered under
the Securities Act of 1933, as amended (the "Act") and that the
certificate representing the Shares shall bear a legend
accordingly.  The Executive represents and warrants to the Company
that he is acquiring the Shares for investment and not with a view
to transfer or re-distribution.  The Executive shall hold the
Shares for a period of two (2) years, unless the same are
registered under the Act.  The Company shall have no duty to
register the Shares.

     5.  Expenses; Automobile:  Lifka is authorized to incur
reasonable travel, entertainment and related expenses incidental to
the performance of his duties under this Agreement.  The Company
will pay or reimburse Lifka for commutation expenses to and from
South Carolina on a weekly basis, and local living expenses in the
area of Shelton, Connecticut.  If Lifka advances the funds for any
such expenses, the Company will reimburse him upon his presentation
of adequate documentation of expenses, in accordance with standard
Company practices.  Lifka shall also be entitled to the use of a
Company-paid leased or rented automobile in accordance with
standard Company policy for senior executives.

     6.  Termination:  Except as otherwise expressly provided
herein, this Employment Agreement may be terminated as follows:

         (a)  By the resignation of Executive, upon the date of
such resignation;

         (b)  Automatically, upon the death of the Executive; or

         (c)  At any time, upon election by the Board
of Directors of the Company

     7.  Compensation Upon Termination:

         (a)  Termination by the Company.  Lifka agrees he is
employed by the Company at the will of the Board and his employment
may be terminated with or without cause of any kind at the
direction of the Board.  All salary and other cash compensation
shall cease upon any such termination; however, Lifka shall be
entitled to retain all of the Shares.

         (b)  Termination by Lifka.  In the event of any
resignation by Lifka, his compensation shall terminate upon the
happening of such resignation, except that if Lifka provides the
Board with reasonable notice of such resignation, the Board may
elect to continue Executive's base compensation for a period

(a) These calculations are submitted in accordance with SEC Release

    No. 15 because the additional incremental shares are
    anti-dilutive and decrease the reported net loss per share.
