TEMPE, Arizona, February 28, 2007 – Comtech EF Data Corporation announced today that it was the recipient of the 2007 Teleport Technology of the Year Award by the World Teleport Association (WTA) for its DoubleTalk™ Carrier-in-Carrier® technology.  The WTA presents the Teleport Awards for Excellence each year to organizations and individuals whose achievements have been deemed exceptional by the international trade association and its awards committee.

A unanimous selection by WTA's Technology of the Year committee, DoubleTalk Carrier-in-Carrier by Comtech EF Data was cited for its ability to reduce bandwidth requirements by 50% nominally, while keeping equivalent throughput and performance.  The technology allows for both sides of a duplex link to be transmitted concurrently in the same segment of transponder bandwidth, which is of critical importance to teleport operators seeking to drive down costs and gain efficiencies as they serve customers. 

"'If you sign the checks for space segment,' one of our committee members said, 'then this technology must be considered a true innovation that will continue to create value and shift the economics for anyone who chooses to adopt this method,'" said Louis A. Zacharilla, director of development for World Teleport Association, quoting one of the members of the awards committee.  Zacharilla once again served as the emcee of the 12th annual Awards luncheon and ceremony.

Comtech EF Data’s CDM-Qx and CDM-QxL Multi-Channel Satellite Modems are the first modems to present the powerful DoubleTalk Carrier-in-Carrier functionality.  Designed for bandwidth compression, Carrier-in-Carrier is based on Applied Signal Technology’s DoubleTalk™, which uses the patented "Adaptive Cancellation" technology. 

"We are honored to be the recipient of this esteemed award," said Daniel Enns, senior vice president strategic marketing and business development for Comtech EF Data.  "We appreciate the WTA's recognition of the unprecedented bandwidth savings that our DoubleTalk Carrier-in-Carrier offers for teleport operators, service providers and enterprise users."

The CDM-Qx and CDM-QxL Satellite Modems have a modular architecture that fits in a 1RU chassis. The unique 4-slot chassis allows a cost-effective deployment of multiple modulators, demodulators or modems.  CDM-Qx and CDM-QxL with DoubleTalk Carrier-in-Carrier address common challenges encountered in satellite communications, including reducing operating expenses for full-duplex links, increasing throughput or availability of full-duplex links without using additional transponder resources, reducing capital expenses by allowing a smaller BUC/HPA and/or antenna and managing limited rack space.
