Comtech EF Data Licenses DoubleTalk Technology

TEMPE, Ariz., Aug 12, 2004 (BUSINESS WIRE) -- Comtech EF Data Corporation, a subsidiary of Comtech Telecommunications Corp. (NASDAQ: CMTL), announced today that it has licensed Applied Signal Technology's (NASDAQ: APSG) DoubleTalk(TM) bandwidth compression system. The licensing arrangement will enable Comtech EF Data to integrate additional bandwidth savings functionality into its satellite modems.

Designed for bandwidth compression, DoubleTalk is based on Applied Signal Technology's "Adaptive Cancellation," a patent pending technology that allows full duplex satellite links to transmit concurrently in the same segment of transponder bandwidth. When properly deployed, this technology can provide significant bandwidth savings.

"Licensing and embedding this technology complements and expands the other bandwidth efficient features offered in Comtech EF Data's satellite modems," said Daniel Enns, senior vice president, strategic marketing and business development.

Comtech EF Data will offer the DoubleTalk technology commercially packaged as Carrier-in-Carrier(TM). This added dimension will result in a significant improvement in satellite transponder utilization to operators and users of satellite communications. When combined with Comtech EF Data's advanced forward error correction and modulation techniques, Carrier-in-Carrier will deliver unprecedented operating expense savings.

"The integration of DoubleTalk into Comtech EF Data's modems is a natural evolution of our bandwidth efficient technology," said Ben Scribner, executive vice president of Applied Signal Technology.
