Cambridge Telcom Report, August 23, 1999

ADTRAN, Inc. (NASDAQ:ADTN) announced Monday a contract with Bell Atlantic to provide the industry's first NEBS Level 3 compliant dual T1, license-free radio -- ADTRAN's TRACER. As the result of a rigorous selection process, Bell Atlantic has chosen ADTRAN for wireless unlicensed T1 connectivity for voice and data transmission. TRACER will be deployed in various applications including last-mile access where wireline options are either difficult or unavailable.

"Bell Atlantic has identified TRACER as a solution for certain last mile deployment requirements," said Tom Stanton, General Manager of ADTRAN's Carrier Networks Division. "TRACER's unique functionality and deployment costs were factors in establishing it as a viable solution, as was ADTRAN's inherent understanding of Bell Atlantic's overall requirements such as NEBS testing. Our existing relationship with Bell Atlantic enables us to provide comprehensive support for its wireless applications."

ADTRAN's TRACER uses spread spectrum microwave technology for reliable digital delivery of dual T1 capacity at up to 30 miles point-to-point. TRACER also operates license-free in the 2.4 GHz Industrial, Scientific, and Medical (ISM) band, allowing immediate deployment. With a choice of rackmount or mastmount configurations that are fully compatible with legacy T1 products, installation is fast and easy.
