BOULDER, Colo.--(BUSINESS WIRE)--Aug. 21, 2001

Carrier Access Corporation (Nasdaq:CACS), an equipment manufacturer that helps more than 1,800 telecommunications companies accelerate service revenue, lower operating costs and extend capital budgets, today announced new wireless product features for both its Adit 600(TM) and Access Navigator(TM) platforms.

The upgrades reduce capital expenditures and decrease costly implementation time by enabling the Adit 600 and Access Navigator to plug and play with power typically found in wireless and fixed wireless installations.

As space and heat requirements become more important to wireless carriers, power supply configurations have changed from -48VDC, plus converter, to +24VDC power supply direct. Carrier Access has addressed these needs by offering a solution that does not require additional power conversion steps, decreasing both the product implementation time and the need for additional expenditures. By engineering +24VDC power supplies for both the Adit 600 and Access Navigator platforms, Carrier Access further demonstrates its commitment to wireless service provider customers. Today, Carrier Access offers a wide array of solutions to the wireless market, including efficient and standardized cross-connect transport and access devices.

"From our fourth quarter in 2000 to our second quarter in 2001, Carrier Access increased its percentage of sales in target markets, including wireless, incumbent and global providers, by 51 percent," said Mark Nixon, vice president of marketing for Carrier Access. "The +24VDC upgrades are an excellent example of our commitment to providing cost-saving solutions to our wireless customers, routinely collapsing cost structures with a 2:1 advantage, while enabling new service revenues."

"The Adit 600 and Access Navigator solutions address wireless operators' current and future infrastructure challenges as they migrate their networks to 3G," said Phil Marshall, senior wireless technology analyst for the Yankee Group.

Carrier Access' Adit 600 and Access Navigator allow telecommunications carriers to optimize capital budgets and make better use of existing network resources. By decreasing operating and maintenance costs through remote management and provisioning, the Adit 600 and the Access Navigator offer affordable and cost-effective backhaul and cell site termination, while enabling a true migration path to the future. With the Adit 600, carriers can offer voice, video and high-speed data services using economical broadband access over wire line and wireless networks. The Access Navigator enables carriers to offer an economical 32 T1 1/0 Digital Cross-Connect System, including a model that leverages the Telcordia(TM) standard GR-303 switching protocol for voice concentration and over-subscription.
