Carrier Access Signs 3-Year Supply Agreement With Cingular to Provide Next-Generation RAN Equipment

BOULDER, COLORADO - July 25, 2006 - Carrier Access Corporation (NASDAQ: CACS) (www.carrieraccess.com ) today announced that they have signed a three year supply agreement with Cingular Wireless to provide next generation equipment for their radio access network (RAN).

The selection by Cingular of the Carrier Access MASTERseries^TM platform, with FLEXengine^TM technology, extends the relationship by adding new products that provide a broader range of data networking solutions for Cingular. FLEXengine technology, incorporates IP management, voice and data prioritization, dynamic bandwidth re-use, and transport data convergence.

FLEXengine technology enables mobile operators to provide high-capacity voice and data services reliably over multiple T1/E1, optical, or Ethernet Radio Access Network connections. This allows Cingular to provide multimedia data services such as music downloads, email, web browsing, and video over their cellular networks, with higher reliability and at lower costs.

Cingular has over 47,000 cell sites, of which over 17,000 are already installed with Carrier Access MASTERseries nodes. This new contract not only gives Carrier Access the opportunity to place new nodes in the remaining 30,000 sites, but also the ability to upgrade the existing sites with incremental hardware and software capabilities.

Carrier Access also provides value-added services to Cingular, including installation and technical services.
