                                3,190,591 Shares

                       FASTCOMM COMMUNICATIONS CORPORATION

                                  Common Stock


     This Prospectus  relates to 3,190,591  shares (the "Shares" or the "Offered
Shares") of common  stock,  par value $.01 per share (the  "Common  Stock"),  of
FastComm Communications Corporation, a Virginia corporation (the "Company"). The
Shares are issuable by the Company upon:  (i) the  conversion of (a)  $5,000,000
principal   amount  of  the   Company's   1997   Convertible   Debentures   (the
"Debentures"), or (b) if approved by the Company's, shareholders,  conversion of
shares of a to-be created class of Series A Preferred  Stock of the Company into
which the Debentures  may be converted at the option of the Company  ("Preferred
Stock");  and (ii)  exercise of the warrants  (the  "Warrants")  issuable  under
certain  circumstances,  upon conversion of Debentures and Preferred  Stock. The
Company  issued  the  Debentures  in a  private  placement  transaction  to four
accredited  investors.  See "Selling  Shareholders."  Additional Shares that may
become issuable as a result of the  anti-dilution  or default  provisions of the
Debentures (or Preferred  Stock) and the Warrants are offered hereby pursuant to
Rule 416 under the Securities Act of 1933, as amended (the "Securities Act"). In
addition,  190,551 of the Shares have been, or may be, issued to Richard L. Apel
in  connection  with  the  acquisition  by  the  Company  of  Comstat   DataComm
Corporation on January 31, 1997. See "Selling Shareholders."

     The Company  will not receive any  proceeds  from the sale of Shares by the
Selling  Shareholders,  but will  receive the  exercise  price  payable upon the
exercise of the Warrants if those  Warrants are issued and  exercised  for cash.
There can be no assurance that all or any part of the Warrants will be issued or
that they will be exercised for cash. All expenses  incurred in connection  with
this  offering are being borne by the  Company,  other than any  commissions  or
discounts paid or allowed by the Selling Shareholders to underwriters,  dealers,
brokers or agents and legal fees of counsel to the Selling Shareholders, if any.

     The Shares being registered under the Registration  Statement of which this
Prospectus  is a part may be  offered  for sale  from time to time by or for the
account of such Selling  Shareholders in the open market, on the NASDAQ National
Market, in privately negotiated transactions,  in an underwritten offering, or a
combination of such methods, at market prices prevailing at the time of sale, at
prices related to such  prevailing  market prices or at negotiated  prices.  The
Offered  Shares are  intended to be sold through one or more  broker-dealers  or
directly to purchasers. Such broker-dealers may receive compensation in the form
of commissions,  discounts or concessions from the Selling  Shareholders  and/or
purchasers of the Offered Shares for whom such  broker-dealers may act as agent,
or to whom  they may sell as  principal,  or both  (which  compensation  as to a
particular broker-dealer may be in excess of customary concessions). The Selling
Shareholders  and any  broker-dealers  who act in  connection  with  the sale of
Offered Shares hereunder may be deemed to be  "underwriters"  within the meaning
of the Securities Act, and any commissions  received by them and proceeds of any
resale of the  Offered  Shares may be deemed to be  underwriting  discounts  and
commissions  under the Securities Act, See "Selling  Shareholders"  and "Plan of
Distribution."

     The Common Stock of the Company is listed on the NASDAQ-NMS (Symbol; FSCX).
The Shares  offered  hereby  involve a high degree of RISK.  See  "CERTAIN  RISK
FACTORS" at page 3 of this Prospectus.

$4,084,000, and $631,000 for the years ended April 30, 1994, 1995 and 1996 and a
net loss of  $675,000  for the nine (9) months  ending  February  1, 1997.  Such
losses are primarily attributable to sales levels insufficient to meet the costs
associated  with the  development  and  marketing of new products in an emerging
technology.  Sales  levels  have been  negatively  impacted by delays in product
development,  delays on the part of the  carriers to offer frame relay  services
and once offered,  incorrect carrier pricing for frame relay services.  In order
to address  these  factors,  the Company has taken  various  steps.  The Company
actively  participates  in  industry  forums  that  promote  frame relay and ATM
services.  Further,  the Company  upgraded and expanded it sales,  marketing and
engineering  organizations,  while  decreasing  its general  and  administrative
overhead.  The Company is focused on acquisitions  and partnership  arrangements
intended  to expand its  technology  base and  increase  sales.  There can be no
assurance that the Company will generate sufficient revenues to meet expenses or
to operate profitably in the future.

     2. Historical  Financial Statement  Adjustments.  During the fourth quarter
ended April 30, 1995, the Company  increased its allowance for doubtful accounts
by $200,000 ($0.02 per share) to take account of products  returned and credited
to  customers  in the  fourth  quarter as well as to  provide  for future  sales
returns and  allowances.  The Company also  increased  its reserve for inventory
obsolescence  in the fourth quarter by $295,000  ($0.04 per share)  primarily to
take account of certain slow moving data compression and analog modem inventory.

     During the fourth quarter ended April 30, 1994, the Company reversed a sale
in the amount of $580,000  which was  originally  recorded in the third  quarter
ended  February  5,  1994.  The  reversal  of the sale was  made  after  certain
technical  difficulties  arose in the fourth  quarter  regarding the project for
which the Company's  product was intended.  These matters were not identified to
management  at the time of sale.  The effect on third  quarter  and fiscal  1994
operating  results  of the  reversal  of the  sale was to  increase  net loss by
approximately  $295,000,  and to increase  the per share net loss by ($0.04) per
share.

     Also during the fiscal  1994 fourth  quarter,  the  Company  increased  its
allowance for doubtful  accounts for products returned and credited to customers
in the fourth  quarter as well as to provide for  potential  future  returns and
allowances. The increase in the allowance includes $220,000 which management now
believed was  attributable to matters which existed at the end of third quarter.
The effect on third quarter and fiscal 1994 and operating  results of increasing
the allowance for doubtful  accounts by $220,000 was to increase the net loss by
$220,000 and to increase the net loss per share by ($0.03).

     The Company restated its 1993 financial  statements to reflect  corrections
to the accounts  payable,  costs of goods sold and  additional  paid-in  capital
accounts,  in connection  with the re-audit of the 1993 financial  statements by
the Company's  accountants  BDO Seidman LLP. With respect to the 1993  financial
statements,  the  restatement  reduced the pre-tax  income and the net income by
$90,000 ($0.01 per share). The restatement had no effect on total  stockholders'
equity as originally reported.

     3. Pending SEC  Investigation.  The United States  Securities  and Exchange
Commission ("SEC") is currently  conducting a confidential inquiry pursuant to a
formal order directing a private investigation. This inquiry, which commenced in
September,  1994 and has focused on certain accounting,  end of quarter, revenue
recognition,  and internal  controls  issues,  is confidential and should not be
construed as an  indication  by the SEC or the staff that any  violations of law
have occurred. The Company is cooperating fully with the SEC staff. No assurance
can be given  concerning the outcome of this  investigation  or that the inquiry
will be resolved in the near future.

     4.   Fluctuations  in  Quarterly   Operating   Results.   The  Company  has
historically  experienced  substantial  quarterly  fluctuation  in its operating
results.  Due to changes to software and the  relatively  high revenues per unit
sold,   production  or  shipping  delays  or  customer  order  rescheduling  can
significantly  affect  quarterly  revenues  and  profitability.  The Company has
experienced and may again experience quarters during which a substantial portion
of  the  Company's  net  sales  are  realized  near  the  end  of  the  quarter.
Accordingly,  delays in shipments near the end of a quarter can cause  quarterly
net sales to fall significantly short of anticipated  levels.  Since most of the
Company's  expenses are fixed in the short term,  such  shortfalls  in net sales
could have a material  adverse  effect on the Company's  business and results of
operations.  The  Company's  operating  results  may also vary from  quarter  to
quarter  based  upon  numerous  factors  including  the  timing  of new  product
introductions,  product  mix,  levels  of sales,  proportions  of  domestic  and
international  sales  activities  of  competitors,  acquisitions,  international
events and problems in obtaining  adequate  materials or  components on a timely
basis.


                                        3



     5. Competition.  The data communications industry is intensely competitive.
The Company currently  competes  principally in the markets for high-speed voice
and data frame relay  products.  Many of the  Company's  existing and  potential
competitors  (including  certain of the company's  customers and suppliers) have
far more extensive financial,  engineering,  product development,  manufacturing
and marketing  resources than the Company.  The Company's  products and services
compete on the basis of a number of factors, including, in the case of the frame
relay business,  time to market and delivery risk, price, quality,  features and
functions,  power consumption,  and manufacturing rights, and recommendations of
the systems integrators, modularity and expendability,  reliability, service and
support,  supplier  credibility,  and  price.  There  can be no  assurance  that
competitors will not introduce products incorporating  technology as advanced or
more  advanced  than  the  Company's  or  that  changes  in  the  communications
environment will not render competitors product solutions more attractive to the
customer than the Company's solutions.  Competitive  pressures often necessitate
price  reductions  which the  Company  may not be able to achieve or which could
adversely affect profit margins which can adversely affect operating results. As
a result,  these  competitors  may be able to  respond  more  quickly  to new or
emerging technologies and changes in customer requirements, or to devote greater
resources to the development,  promotion and sale of their products and services
than  the  Company.  In  addition,   current  and  potential   competitors  have
established or may establish cooperative  relationships among themselves or with
third  parties  to address  the needs of the  Company's  prospective  customers.
Accordingly,  it is possible that new competitors or alliances among competitors
may  emerge  and  rapidly  acquire  significant  market  share.  There can be no
assurance that the Company will be able to compete successfully with existing or
new  competitors or that  competitive  pressures  faced by the Company would not
materially  and  adversely  affect  its  business,  results  of  operations,  or
financial condition.

     6. Rapid  Technological  Change.  The market for the Company's  products is
characterized  by rapidly  changing  technology,  emerging  industry  standards,
product  proliferation and short product life cycles.  The Company believes that
its future success will depend upon its ability to enhance its existing products
and to develop and introduce new products  which conform to or support  emerging
data  communications  standards,  meet a wide range of  evolving  user needs and
achieve  market  acceptance.  There can be no  assurance  that the Company  will
succeed in developing  and  marketing  such products or that the Company will be
able  to  respond  effectively  to  technological  changes,   emerging  industry
standards or new product introductions by others.  Furthermore,  there can be no
assurance that competitors will not introduce products incorporating  technology
as advanced or more advanced than the Company's  thereby rendering the Company's
products or technologies  uncompetitive or obsolete.  Any significant  delays in
developing  or shipping  new or enhanced  products  could  adversely  affect the
Company's  operating  results.   Conversely,   the  growth  of  the  market  for
communications  products  has been  driven  in part by the  rapid  technological
change  experienced  by that market.  There can be no assurance  that such rapid
technological change will continue or that the telecommunications infrastructure
will support such  products.  Any of these  factors could  materially  adversely
affect the market for data  communications  products and the Company's operating
results.


     7. Changes to Protocols and Changing Technology.  New Data Protocols may be
developed  that could  displace  the  protocols  currently  supported in Company
products,  requiring additional software development to sustain the viability of
those  products.  An  announcement  of such new protocols  could have a negative
effect on sales of older designs,  as users hesitate to install  equipment based
on  existing  designs  until they had  evaluated  the new ones.  There can be no
assurance that the Company would have the necessary resources,  particularly the
knowledgeable  employees,  to implement new protocols in a timely  manner.  Such
failure to  develop  adequate  products  in  response  to new  technology  could
adversely affect the Company's  profitability.  Asynchronous Transfer Mode (ATM)
is a new technology for transmitting  digital  information,  including voice and
data, over a public or private network.  Telephone companies and other operators
of public  network are  deploying  ATM in their  backbone  segments.  If the ATM
technology becomes much less expensive,  ATM services could become  economically
more  attractive  than frame relay  services that  currently are involved in the
bulk of  Company's  business.  If ATM were to become  more  popular  that  frame
replay,  the Company would need to develop new products,  retrain its employees,
and  educate  its  sales  and  distribution  channel  partners.  There can be no
assurance  that  the  Company  will  have the  resources  necessary  to  develop
appropriate products in a timely manner.

     8. Introduction of New Products.  The Company's future revenue is dependent
on its ability to successfully develop, manufacture and market products. In this
regard,  future  growth is  dependent  on the  Company's  ability  to timely and
successfully  develop and  introduce new  products,  establish new  distribution
channels, develop affiliations with leading market participants which facilitate
product development and distribution,  and market existing and new products with
service providers,  resellers, channel partners, and others. The introduction of
new or enhanced  products  requires  the Company to manage the  transition  from
older products in order to minimize  disruption in customer  ordering  patterns,
avoid  excessive  levels of older product  inventories  and ensure that adequate
supplies of new products can be delivered to meet customer demand.  In addition,
as  the  technical   complexity  of  new  products  increases,   it  may  become
increasingly  difficult  to  introduce  new  products  quickly and  according to
schedule.  There can be no assurance that the Company will  successfully  manage
the  transition to new products or that the Company's  research and  development
efforts will result in  commercially  successful  new technology and products in
the future.

     9.  Future  Capital  Requirements.  The  Company's  ability to make  future
capital  expenditures  and fund the development and launch of new products,  are
dependent on existing cash and some or all of the following:  demands on cash to
support  inventory  for the  frame  relay,  demands  on cash  arising  from  the
redemption (if required) of the Debentures or Preferred Stock, and the Company's
return to  profitability.  The timing and amount of the Company's future capital
requirements  can not be  accurately  predicted,  nor can there be any assurance
that debt or equity financing, if required, can be obtained on acceptable terms.
There can be no  assurance  that the  company  will have cash  available  in the
amounts and at the times needed.

     10.  Dependence on Key  Employees.  The Company's  ability to implement its
strategies  depends  upon its ability to retain and  continue to attract  highly
talented managerial and technical personnel. The Company is especially dependent
on its key technical  personnel to remain in the forefront of technology  and on
its sales  executives  to develop and  implement  the sales  strategies  for its
products.   Competition   for  qualified   personnel  is  intense  in  the  data
communications  industry. Most of the Company's senior executives,  are employed
on an "at-will"  basis.  There can be no assurance  that the Company will retain
its  key  managerial  and  technical  employees  or that  it  will  attract  and
assimilate,  such  employees  in the  future  . The  loss of key  management  or
technical   personnel  could  materially  and  adversely  affect  the  Company's
business, results of operations and financial condition.

     11.  Inventory  Management.  From time to time, the Company has experienced
significant  increases in its levels of  inventory  in order to meet  production
requirements  of  existing or  anticipated  orders or as the result of delays in
receiving certain components,  such as critical chipsets, from suppliers and the
concurrent accumulation of other inventory.  Increased levels of inventory could
adversely  affect  the  Company's  liquidity,  increase  the  risk of  inventory
obsolescence (from cancellation of orders, failure to receive anticipated orders
or  otherwise),  or  increase  the risk of a  decline  in  market  value of such
inventory or losses from theft, fire or other similar  occurrences.  The failure
of the Company to effectively  manage its inventory levels could have a material
adverse affect on the Company's financial condition and results of operations.


                                        4



     12.  Intellectual  Property Rights.  The Company's  success depends in part
upon its technological  expertise and proprietary  product designs.  The Company
relies upon its trade secret  protection  efforts and, to a lesser extent,  upon
patents and copyrights to protect its proprietary technologies.  There can be no
assurance  that  these  steps  will be  adequate  to deter  misappropriation  or
infringement of its proprietary  technologies or that the Company's  competitors
will not independently develop technologies that are substantially equivalent or
superior to the  Company's  technology.  In  addition,  the laws of some foreign
countries do not protect the Company's  proprietary rights to the same extent as
do the  laws of the  United  States.  Further,  given  the  rapid  evolution  of
technology  and  uncertainties  in  intellectual  property law,  there can be no
assurance that the Company's  current or future  products will not be determined
to infringe proprietary rights of others.  Should the Company be sued for patent
infringement,  there can be no assurance  that the Company will prevail,  or, if
required  by such  litigation,  that it will  be able to  obtain  the  requisite
licenses or rights to use such technology on commercially  reasonable  terms. In
addition, any litigation, regardless of the outcome, could result in substantial
costs to the Company.

     13. Regulatory Standards.  The Company's products are subject to regulation
by the Federal Communications  Commission (the "FCC"), and each of the Company's
products must  typically be tested before it can be introduced  into the market.
Any inability of the  Company's  products to conform to FCC  regulations  or any
failure of the Company's  products to meet FCC testing  requirements could delay
the introduction of the Company's products into the market, impact the Company's
relationships with its OEMs and otherwise adversely affect the Company.  Foreign
authorities often establish telecommunications standards different from those in
the United  States,  making it difficult and more  time-consuming  to obtain the
required  regulatory   approvals.   Any  significant  delay  in  obtaining  such
regulatory  approvals  could have an adverse  effect on the Company's  operating
results.   Furthermore,   changes  in  such  laws,   regulations,   policies  or
requirements could affect the demand for the Company's products or result in the
need to modify products,  which may involve substantial costs or delays in sales
and could have an adverse effect on the Company's future operating results.

     14.  Potential  Redemption of Debentures  or Preferred  Stock.  Pursuant to
regulations of the National Association of Securities Dealers, in the absence of
shareholder  approval,  the Company may not issue,  in the aggregate,  more than
2,016,261 shares of Common Stock upon conversion of the Debentures (or Preferred
Stock) and the exercise of the  Warrants.  The actual number of shares of Common
Stock to be issued upon  conversion of the Debentures (or Preferred  Stock) will
depend on the average closing price of the Common Stock prior to conversion. The
Company is obligated  to redeem any shares of  Preferred  Stock which may not be
converted  and any  Warrants  which  may not be  exercised  as a result  of such
regulatory limitation.  The cash demands to fund such a redemption may adversely
affect the Company's  ability to make future capital  expenditures  and fund the
development and launch of new products.  Furthermore,  there can be no assurance
that the Company will have cash available to fund such a redemption. See "Future
Capital Requirements".

     15. Potential Dilution;  Shares Eligible for Future Sales;  Possible Effect
on Additional Equity Financing.  A substantial  number of shares of Common Stock
are or will be  issuable  by the  Company  upon the  conversion  of  convertible
Debentures  (or Preferred  Stock) and the exercise of Warrants which the Company
has  issued,  which  could  result in  dilution  to a  shareholder's  percentage
ownership interest in the Company and could adversely affect the market price of
the Common Stock.  Under the  applicable  conversion  formulas of the Debentures
(and  Preferred  Stock),  the  number of shares of Common  Stock  issuable  upon
conversion is inversely  proportional to the market price of the Common Stock at
the time of conversion (i.e., the number of shares increases as the market price
of the Common Stock  decreases):  and except with respect to certain  redemption
rights of the Company for the Debentures (or Preferred  Stock),  there is no cap
on the number of shares of Common Stock which may be issued.  In  addition,  the
number of shares  issuable upon the  conversion of the  Debentures (or Preferred
Stock) and the exercise of Warrants is subject to adjustment upon the occurrence
of certain dilutive events after October 9, 1997.

     On April 15, 1997,  there were issued and outstanding a total of 10,081,307
shares of Common Stock. If all convertible  Debentures (or Preferred  Stock) and
Warrants Issuable  Conversion which the Company has issued were deemed converted
and exercised, as the case may be, as of April 15, 1997, there would be issuable
1,160,622 shares of Common Stock. Upon such conversion and exercise, there would
be  outstanding  11,241,929  shares  of Common  Stock.  Of  these,  the  Company
currently has  registered  for resale  3,000,000  shares  (including  the Shares
offered hereby).  The sale or availability  for sale of a significant  number of
shares of Common Stock in the public  market could  adversely  affect the market
price  of  the  Common  Stock.  In  addition,  certain  holders  of  outstanding
securities of the Company have rights to approve  and/or  participate in certain
types of future equity financing by the Company. The availability to the Company
of additional  equity  financing,  and the terms of any such  financing,  may be
adversely affected by the foregoing.

     16.  Price  Volatility  and Absence of  Dividends.  The market price of the
Company's  Common Stock has been, and may continue to be, highly  volatile.  The
Company  believes  that  factors such as  quarterly  fluctuations  in results of
operations,   adverse   circumstances   affecting  the  introduction  or  market
acceptance of new products offered by the Company, announcements of new products
by competitors, changes in earnings estimates by analysts, changes in accounting
principles, sales by existing shareholders (including sales from time to time by
the Selling Shareholders), loss of key personnel and other factors will continue
to  cause  the  market  price  of  the  Company's   Common  Stock  to  fluctuate
substantially.   In  addition,  stock  prices  for  many  technology  companies,
including  the  Company,  fluctuate  widely  for other  reasons  (such as market
perception of high technology  industries) unrelated to operating results. These
fluctuations as well as general economic,  political and market conditions, such
as recessions or military  conflicts,  may adversely  affect the market price of
the Company's  Common Stock.  Changes in the price of the Company's Common Stock
could affect the Company's ability to successfully  attract and retain qualified
personnel or complete other  transactions  in the future.  The Company has never
paid any cash dividends on its capital  stock,  and has no plans to do so in the
future.


                                        5



                                   THE COMPANY

The  Company  participates  in the  communications  networking  industry,  which
divides logically into two major areas:

     1.   Backbone  systems and  components:  consisting  of large  switches and
          multiplexers,  connected  to each  other by Wide  Area  Network  (WAN)
          transmission lines. Public networks put backbone components in Central
          Offices.  Private networks place them at headquarters,  major regional
          centers, and the larger branch locations.

     2.   Access  devices:  this  equipment  is  physically  smaller,  typically
          located  in remote  customer  offices  and  attached  to the  backbone
          network through a single or multiple telephone lines. An access device
          may be part of a local area network  (LAN) within a building or campus
          and/or   facilitate   connection   among  and   between  LAN  and  WAN
          environments.

FastComm  designs,  manufactures,  markets,  and sells access devices that allow
computer  users to connect to public and  private  networks  based on analog and
digital transmission.  Its products include a range of devices aimed at the fast
packet  services as well as digital  leased-lines,  switched 56 networks  and ID
route networks (including the Internet). The Company's access devices allow many
types of terminal equipment and computers to access these services.  The Company
does not make backbone network components or systems, but is focused on the much
simpler access  devices.  The market  potential (in units) is greater for access
products  because  there  are so many  small  offices  and  businesses  that are
increasingly able to justify a digital connection.

     The Company's  current  business is primarily  based on access  devices for
frame relay services.  Other access products offered include models designed for
cell relay or ATM services (a LAN  bridge),  analog  phone lines  (modems),  and
leased or switched  digital data  services  (CSU/DSUs  for DDS).  FastComm  also
offers a family of  moderate  to very high  speed  data  compressors  to enhance
access to digital services.

     The Company manufactures some of its products at its headquarters  location
in Sterling, Virginia. It also resells products manufactured by others under its
label. The Company  subcontracts the manufacturing of its printed circuit boards
to various  outside,  unrelated  contractors and performs the final assembly and
testing at its headquarters.

     The Company  maintains  its  principal  executive  offices at 45472 Holiday
Drive, Sterling, Virginia 20166 and its telephone number is (703) 318- 7750.

                                 USE OF PROCEEDS

     The  Company  will not receive  any  proceeds  form the sale of the Offered
Shares by the Selling  Shareholders.  The Company  will use the  proceeds of any
exercise of the  Warrants  for cash for general  corporate  purposes and working
capital.

                              SELLING SHAREHOLDERS

     The following table sets forth the names of the Selling  Shareholders,  the
number of Common Shares  beneficially  owned by such Selling  Shareholder  as of
April 15,  1997 and the number of Offered  Shares  which may be offered for sale
pursuant  to this  Prospectus  by each  such  Selling  Shareholder.  None of the
Selling  Shareholders  has  held  any  position,   offices,  or  other  material
relationship  with the  Company or any of its  affiliates  within the past three
years  other  than as a result of his or its  ownership  of Common  Shares.  The
Offered  Shares may be  offered  from time to time by the  Selling  Shareholders
named below.  However, such Selling Shareholders are under no obligation to sell
all or any portion of such  Offered  Shares,  nor are the  Selling  Shareholders
obligated to sell any such Offered Shares immediately under this Prospectus. All
information  with respect to share  ownership has been  furnished by the Selling
Shareholders. Because Selling Shareholders may sell all or part of their Offered
Shares,  no estimate can be given as to the number of Common Shares that will be
held by any Selling Shareholder upon termination of any offering made hereby.

     Pursuant to Rule 416 of the Securities Act, Selling  Shareholders many also
offer and sell Common Shares issued with respect to the Debentures (or Preferred
Stock)  and the  Warrants  as a result  of stock  splits,  stock  dividends  and
anti-dilution provisions (including by reason of changes in the conversion price
of the Debentures and Preferred Stock in accordance with the terms thereof)

     (2) Pursuant to the  Securities  Purchase  Agreement,  dated April 9, 1997,
among the Company and Capital Ventures International,  Nelson Partners,  Olympus
Securities,  Ltd., CC Investments,  LDC.  (collectively,  the "Investors"),  the
Investors  purchased an aggregate of $5,000,000  principal amount of Debentures,
which are  convertible  upon  approval  of the Company  Stockholders  into 5,000
shares of Preferred  Stock.  The Debentures  (or shares of Preferred  Stock) are
convertible into Shares of Common Stock and Warrants (the "Warrants") to acquire
a number of shares of Common  Stock  equal to up to forty  percent  (40%) of the
number of shares of Common Stock issuable upon  conversion of each Debenture and
share of Preferred Stock.

(3)  Represents the pro rata allocation  among the Investors of 3,000,000 Shares
     which the Company is  registering  hereunder  pursuant to the  registration
     rights  agreement  attached  as Exhibit 4.3  hereto.  The actual  number of
     Common Shares issuable upon  conversion of the  Convertible  Debentures (or
     Preferred Stock) will equal (in addition to the Common Shares issuable upon
     exercise  of the  Warrants),  (i) the  aggregate  principal  amount  of the
     Debentures  or stated  value of the  shares of  Preferred  Stock then being
     converted (plus a premium in the amount of 5% per annum accruing from April
     9, 1997,  through the date of conversion (unless the Company chooses to pay
     such premium in cash),  plus any  Conversion  Default Amount (as defined in
     the Debentures and the Certificate of  Designations  Preferences and Rights
     of the Preferred Stock), divided by (ii) (x) if the conversion occurs on or
     before  October 6, 1997,  a conversion  price equal to a percentage  of the
     average  closing  price of the shares of Common  Stock  during a  specified
     trading period immediately prior to conversion (as determined in accordance
     with the Debentures or Certificate of Designations Preference and Rights of
     the Preferred Stock), or (y) in the case of conversions on or after October
     6, 1997,  a  conversion  price  equal to the lower of a  percentage  of the
     average  closing  price of the Common  Shares  during a  specified  trading
     period immediately prior to conversion, and $7.54 (subject to adjustment in
     accordance with the Debentures or Certificate of  Designations  Preferences
     and Rights of the Preferred  Stock).  Upon  conversion of the Debentures or
     Preferred  Stock into  shares of Common  Stock,  each holder  thereof  will
     receive  warrants to acquire a number of shares of Common Stock equal to up
     to forty  percent  (40%) of the number of shares of Common  Stock  issuable
     upon conversion of each Debenture or share of Preferred Stock. The Warrants
     entitle the Holder  thereof to acquire  shares of Common  Stock an exercise
     price of 125% of the market  price,  as defined in the Warrants on the date
     of issuance of the Warrants. For a complete description of the terms of the
     Debentures,  see  Exhibit  4.4  hereto.For  a complete  description  of the
     relative rights,  preferences,  privileges,  powers and restrictions of the
     Preferred  Stock,  see the  Certificate of  Designations,  Preferences  and
     rights of Series A Convertible  Preferred Stock of FastComm  Communications
     Corporation attached as Exhibit 4.6 hereto. For complete description of the
     terms of the  Warrants,  see the Form of Warrant  attached  as Exhibit  4.5
     hereto.

     Except under certain limited circumstances,  no holder of the Debentures or
     Preferred  Stock and  Warrants  is  entitled  to convert or  exercise  such
     securities to the extent that the shares to be received by such holder upon
     such  conversion or exercise  would cause such holder to  beneficially  own
     more than 4.9% of the outstanding  shares of Common Stock.  Therefore,  the
     number of Shares set forth herein and which a Selling  Shareholder may sell
     pursuant to this  Prospectus  may exceed the number of Shares such  Selling
     Shareholders  would otherwise  beneficially  own as determined  pursuant to
     Section 13(d) of the Exchange Act. Moreover, pursuant to the regulations of
     the  National   Association  of  Securities  Dealers,  in  the  absence  of
     shareholder  approval,  the  aggregate  number of  shares  of Common  Stock
     issuable to the Selling  Shareholders  at a discount from market price upon
     conversion  of the  Debentures  or  Preferred  Stock  and  exercise  of the
     Warrants  which  have been and may be issued  to the  Selling  Shareholders
     pursuant to the Securities Purchase Agreements may not exceed 19.99% of the
     outstanding Common Shares on April 9, 1997 (i.e., 2,016,261 shares). Unless
     shareholder  approval is obtained  to issue  shares of Common  Stock to the
     Investors  in excess of the  maximum  amount set forth  above,  none of the
     Selling   Shareholders   will  be  entitled   to  acquire   more  than  its
     proportionate  share of such maximum  amount.  Any  Debentures or Preferred
     Stock  which  may  not be  converted  and  any  Warrants  which  may not be
     exercised because of such limitation must be redeemed by the Company.

(4)  Citadel  Limited  Partnership  is the  managing  general  partner of Nelson
     Partners  ("Nelson") and the trading  manager of Olympus  Securities,  Ltd.
     ("Olympus") and consequently  has voting control and investment  discretion
     over securities held by both Nelson and Olympus. The ownership  information
     for Nelson does not include the shares  owned by Olympus and the  ownership
     information for Olympus does not include the shares owned by Nelson.

(5)  Includes  105,520  shares of Stock issued to Richard L. Apel at Closing and
     an   additional   26,380  Shares   issuable  in  accordance   with  certain
     post-closing  adjustments;  also includes an additional 58,651, issuable to
     Mr. Apel in the future if Net Revenue of Comstat Communications Corporation
     exceeds a certain  threshold amount  ("Adjustment  Shares").  The number of
     Adjustment  Shares, if earned, is subject to further adjustment up or down,
     if the average  closing bid price for shares of the Company's  Common Stock
     is greater or less than $6.82 for the five (5) business days proceeding the
     applicable Adjustment Date.

                              PLAN OF DISTRIBUTION

     The Offered Shares are being offered on behalf of the Selling Shareholders,
and,  except for the cash exercise  price of the Warrants,  the Company will not
receive  any  proceeds  from the  Offering.  The  Offered  Shares may be sold or
distributed  from  time to time by the  Selling  Shareholders,  or by  pledgees,
donees or  transferees  of, or other  successors  in  interest  to, the  Selling
Shareholders, directly to one or more purchasers (including pledgees) or through
brokers,  dealers or  underwriters  who may act solely as agents or may  acquire
Offered Shares as principals,  at market prices  prevailing at the time of sale,
at prices related to such prevailing market prices, at negotiated  prices, or at
fixed prices,  which may be changed.  The distribution of the Offered Shares may
be effected  in one or more of the  following  methods:  (i)  ordinary  brokers'
transactions,  which may include long or short sales (ii) transactions involving
cross  or block  trades  or  otherwise  on the  NASDAQ  National  Market;  (iii)
purchases by brokers,  dealers or  underwriters  as principal and resale by such
purchasers  for their own  account  pursuant  to this  Prospectus;  (iv) "at the
market " to or through  market makers or into an existing  market for the Common
Shares;  (v) in other ways not involving  market makers or  established  trading
markets,  including direct sales to purchasers or sales effected through agents;
(vi)  through  transactions  in  options,  swaps or other  derivatives  (whether
exchange-listed or otherwise),  or (vii) any combination of the foregoing, or by
any other legally  available  means.  In addition,  the Selling  Shareholders or
their   successors  in  interest  may  enter  into  hedging   transaction   with
broker-dealers  who may engage in short sales of Offered Shares in the course of
hedging the  positions  they assume with the Selling  Shareholders.  The Selling
Shareholders or their successors in interest may also enter into option or other
transactions   with   broker-dealers   that   require   the   delivery  by  such
broker-dealers  of the  Offered  Shares,  which  Offered  Shares  may be  resold
thereafter pursuant to this Prospectus.

     Brokers, dealers,  underwriters or agents participating in the distribution
of the  Offered  Shares  as  agents  may  receive  compensation  in the  form of
commissions,  discounts  of  concessions  from the Selling  Shareholders  and/or
purchasers of the Offered Shares for whom such  broker-dealers may act as agent,
or to whom  they may sell as  principal,  or both  (which  compensation  as to a
particular   broker-dealer   may  be  less  than  or  in  excess  of   customary
commissions).  The  Selling  Shareholders  and  any  broker-dealers  who  act in
connection  with  the sale of  Offered  Shares  hereunder  may be  deemed  to be
"Underwriters"  within the meaning of the  Securities  Act, and any  commissions
they  receive  and  proceeds  of any sale of Offered  Shares may be deemed to be
underwriting  discounts and commissions  under the Securities  Act.  Neither the
Company nor any Selling  Shareholder  can presently  estimate the amount of such
compensation.  The Company knows of no existing arrangements between any Selling
Shareholder any other shareholder, broker, dealer, underwriter or agent relating
to the sale of distribution of the Offered Shares.

     The Company  will pay  substantially  all of the  expenses  incident to the
registration,  offering and sale of the Offered  Shares to the public other than
commissions or discounts of underwriters,  broker-dealers or agents. The Company
has also agreed to  indemnify  certain of the Selling  Shareholders  and certain
related persons against certain  liabilities,  including  liabilities  under the
Securities Act.

Item 15. Indemnification of Directors and Officers.

     Article Six of the By-Laws, as amended, of the Company empowers the Company
to indemnify current or former directors,  officers,  employees or agents of the
Company or persons  serving by request of the Company in such  capacities in any
other  enterprise  or persons  who have  served by the request of the Company in
such capacities in any other enterprise to the full extent permitted by the laws
of the Commonwealth of Virginia.

     Article Tenth of the Virginia  Stock  Corporation  Act contains  provisions
authorizing indemnification by the Company of directors,  officers, employees or
agents  against  certain  liabilities  and  expenses  which  they  may  incur as
directors,  officers,  employees  or agents of the  Company or of certain  other
entities. Section 13.1 - 699 also provides that such indemnification may include
payment by the  Company of expenses  incurred  in  defending a civil or criminal
action or  proceeding  in advance  of the final  disposition  of such  action or
proceeding  upon receipt of an  undertaking  by the person  indemnified to repay
such  payment  if  he  shall  be   ultimately   found  not  to  be  entitled  to
indemnification  under the Section.  Indemnification may be provided even though
the person to be indemnified is no longer a director, officer, employee or agent
of the  Company  or  such  other  entities.  Section  13.1 - 703  also  contains
provisions  authorizing  the Company to obtain  insurance  on behalf of any such
director,  officer  employee or agent  against  liabilities,  whether or not the
Company would have the power to indemnify such person  against such  liabilities
under the provisions of the Section. The Company currently maintains a policy of
insurance  under which the  directors  and  officers of the Company are insured,
within the limits and subject to the exclusions  and  limitations of the policy,
against  certain  expenses in connection  with the defense of actions,  suits or
proceedings,  to which they are  parties by reason of being or having  been such
directors or officers.

     The  indemnification  and  advancement  of  expenses  provided  pursuant to
Section 13.1 - 699 are not  exclusive,  and subject to certain  conditions,  the
Company may make other or further  indemnification or advancement of expenses of
any of its  directors,  officers,  employees or agents.  Because the Articles of
Incorporation,   as  amended,   of  the  Company  do  not   otherwise   provide,
notwithstanding  the  failure  of the  Company to  provide  indemnification  and
despite a contrary  determination  by the Board of Directors or its shareholders
in a specific case, a director, officer, employee or agent of the Company who is
or was a party to a proceeding  may apply to a court of  competent  jurisdiction
for  indemnification or advancement of expenses or both, and the court may order
indemnification  and  advancement of expenses,  including  expenses  incurred in
seeking   court-ordered   indemnification  or  advancement  of  expenses  if  it
determines that the petitioner is entitled to mandatory indemnification pursuant
to Section 13.1 - 698 because he has been  successful on the merits,  or because
the Company has the power to  indemnify  on a  discretionary  basis  pursuant to
Section 13.1 - 699 or because the court determines that the petitioner is fairly
and reasonably  entitled  indemnification  or advancement of expenses or both in
view of all the relevant circumstances.

     Section 13.1692.1 of the Act provides that the damages assessed against any
officer or director arising out of a single transaction, occurrence or course of
conduct shall not exceed the lesser of (1) the monetary amount  specified in the
Articles of  Incorporation;  or (2) the greater of (i) $100,000 or the amount of
cash  compensation  received by the officer or director from the corporation for
the twelve  (12) months  immediately  proceeding  the act or omission  for which
liability  was  imposed.  The  liability  of an officer or  director  engaged in
willful  misconduct or a knowing  violation of criminal law or of any federal or
state  securities law including  without limit of any claim of unlawful  insider
trading or  manipulation  of the market for any  security is not covered by such
provision.

     The  Agreement  between the Company and the Selling  Stockholders  provides
that  the  Selling  Stockholders  and,  under  certain  circumstances,   persons
participating  as underwriters in the offering or sale of the Common Stock being
registered  will  indemnify  and hold  harmless  the Company and each  director,
officer


                                        9



and controlling  person of the Company with respect to any statement or omission
in the Registration  Statement or the Prospectus based upon written  information
furnished  to the  Company by or on behalf of the Selling  Stockholders  or such
underwriters, as the case may be, for inclusion therein.

Item 17. Undertakings.

A. The undersigned hereby undertakes:

     (1) To file,  during any period in which  offers or sales are being made, a
post-effective amendment to this Registration Statement;

          (i) to include  any  prospectus  required  by Section  10(a)(3) of the
          Securities Act of 1933;

          (ii) to reflect in the  prospectus  any facts or events  arising after
          the  effective  date of the  Registration  Statement  (or most  recent
          post-effective  amendment  thereof)  which,  individually  or  in  the
          aggregate, represent a fundamental change in the information set forth
          in the Registration Statement; and

          (iii) to include any material  information with respect to the plan of
          distribution not previously disclosed in the Registration Statement or
          any material change to such information in the Registration Statement;
          provided,  however,  that  paragraphs  A.(1)(i)  do not  apply  if the
          information  required to be included in a post-effective  amendment by
          those  paragraphs  is  contained  in  periodic  reports  filed  by the
          Registrant  pursuant to Section 13 or Section 15(d) of the  Securities
          Exchange  Act of  1934  that  are  incorporated  by  reference  in the
          Registration Statement.

     (2) that, for the purpose of determining any liability under the Securities
Act of 1933,  each  such  post-effective  amendment  shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities  at that time shall be deemed to the  initial  bona
fide offering thereof.

     (3) to remove from registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering.


                                       10



B.  The  undersigned   registrant   hereby  undertakes  that,  for  purposes  of
determining  any liability  under the securities Act of 1933, each filing of the
registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of  1934  that is  incorporated  by  reference  in the
Registration  Statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

C. Insofar as indemnification  for liabilities  arising under the Securities Act
of 1933 may be permitted to directors,  officers and controlling  persons of the
Company pursuant to the foregoing provisions of otherwise,  the Company has been
advised  that in the opinion of the  Securities  and  Exchange  Commission  such
indemnification  is  against  public  policy  as  expressed  in the  Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such  liabilities  (other than the payment by the Company of express incurred or
paid  by a  director,  officer  or  controlling  person  of the  Company  in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered,  the Company  will,  unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction  the question whether such  indemnification  by it is against pubic
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                                   SIGNATURES

     Pursuant to the  requirements of the Securities Act of 1933, the registrant
certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on Form S-3 and has  duly  caused  this  registration
statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized, in the Town of Sterling, Commonwealth of Virginia on April 30, 1997.
