                          DEREGISTRATION OF SECURITIES

     Concurrent Computer Corporation, a Delaware corporation ("Concurrent"),
filed a Registration Statement on Form S-3 (File No. 333-72012) (the
"Registration Statement") with the Securities and Exchange Commission (the
"Commission") on October 22, 2001, registering 2,054,431 shares of Concurrent's
common stock, par value $.01 per share:  to be sold from time-to-time by two
selling stockholders as follows:

     -    2,000,000 shares for Scientific-Atlanta Strategic Investments, L.L.C.
          ("S-A"); and

     -    54,431 shares for Comcast Concurrent Holdings, Inc ("Comcast").

Concurrent subsequently filed Pre-Effective Amendment No. 1 to the Registration
Statement on November 20, 2001.  The Commission declared the Registration
Statement effective on November 20, 2001.

     In accordance with the undertaking contained in Part II, Item 17(a)(3) of
the Registration Statement pursuant to Item 512(a)(3) of Regulation S-K,
Concurrent files this post-effective amendment to remove from registration all
of the shares which remain unsold under the registration statement as of the
date hereof.  Concurrent is deregistering all shares to be sold by S-A because
the shares to be sold by S-A were issuable upon the exercise of a warrant that
expired unexercised on August 17, 2002.  Concurrent is also deregistering all
shares to be sold by Comcast, because its obligation to maintain the
effectiveness of the Registration Statement with respect to such shares pursuant
to the terms of the registration rights agreement by and between Concurrent and
Comcast dated as of March 29, 2001 has expired.

     Accordingly, Concurrent files this Post-Effective Amendment No. 1 to the
Registration Statement on Form S-3 to deregister 2,054,431 shares of its common
stock covered by the Registration Statement that remain unsold as of the date
hereof.



                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, as amended, and
Rule 478(a)(4) thereunder, 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 Post-Effective Amendment No. 1 to the Registration
Statement on Form S-3 to be signed on its behalf by the undersigned, thereunto
duly authorized, in the city of Duluth, state of Georgia, on October 10, 2003.
