Carrier Access Delays Filing Amendment to Form 10-K for the Period Ended December 31, 2004

Carrier Access Corporation (Nasdaq:CACS), a manufacturer
of broadband communications equipment, today announced that the filing
of a required amendment to its previously filed Annual Report on Form
10-K for the fiscal year ended December 31, 2004 will be delayed
beyond the May 2, 2005 extended filing date.
   As a result of information presented to its auditors, KPMG LLP, in
connection with the Company's 404-review process, Carrier Access is
performing additional detailed review of certain contracts to confirm
language regarding passage of title from specific customer
transactions in situations where the order documentation from such
customers is not consistent. The issue under examination relates to
the passage of title and proper timing of revenue recognition between
calendar quarters in 2003 and 2004.
   When the Company filed its 2004 Form 10-K Report on March 22,
2005, it utilized an order of the Securities and Exchange Commission
permitting a 45-day extension of time within which to include its
annual management report and the related attestation report of the
Company's independent auditors.
   The Company has made substantial progress towards the completion
of its assessment of the effectiveness of its internal control over
financial reporting as of December 31, 2004. However, the Company
believes it is necessary to take additional time to review this issue
to ensure that the timing of the revenue received in these specific
situations has been recorded in the correct period, and both the
Company and the auditors require additional time to complete the
documentation and related audit procedures in connection with the
Company's management report on the effectiveness of the Company's
internal control over financial reporting and the related attestation
report of the Company's independent auditors under Section 404 of the
Sarbanes-Oxley Act of 2002.
   Management has determined that a control deficiency exists because
its internal control procedures did not require a review to determine
whether there are contradictory contractual provisions in existing
customer arrangements that could bear on the appropriate timing of
revenue recognition, and that this control deficiency constitutes a
material weakness as of December 31, 2004. As previously disclosed in
its Form 10-K filed March 22, 2005, management previously disclosed
that a material weakness existed as of December 31, 2004 with respect
to following of control procedures regarding the Statement of Cash
Flows.
   As a result of the Company's delay in filing its required
amendment on Form 10-K/A for 2004, Carrier Access expects to receive
notification from Nasdaq that it is not in compliance with the filing
requirements for continued listing on Nasdaq and that its securities
could be subject to delisting from the Nasdaq National Market. In
addition, Carrier Access anticipates that Nasdaq may change the
Company's trading symbol from "CACS" to "CACSE."
