Comtech Telecommunications Corp. Receives $2.6 Million in Orders to Supply Satcom Equipment for a Cellular Backhaul Network Expansion in Asia.

MELVILLE, N.Y. -- Comtech Telecommunications Corp. (NASDAQ: CMTL) announced today that its Tempe, Arizona-based subsidiary, Comtech EF Data Corp., received $2.6 million in orders for satellite communications equipment. The equipment will support an expansion project of a satellite-based cellular backhaul network to remote areas in Asia. The orders include a mix of Comtech EF Data products, including the CDM-Qx/L Multi-Channel Satellite Modem, the CDM-600/L Satellite Modem, Redundancy Switches and Converters.

The CDM-Qx/L modems are the first Multi-Channel Satellite Modems with a modular architecture in a one rack unit chassis. Designed with the needs of satellite operators, communication service providers and enterprise users in mind, they offer exceptional flexibility, redundancy, integration and performance. The unique four-slot chassis architecture allows a cost-effective deployment of multiple modulators, demodulators or modems. The CDM-Qx/L's are also the first Satellite Modems to offer DoubleTalk Carrier-in-Carrier capability. Carrier-in-Carrier[R] is based on Applied Signal Technology's DoubleTalk[TM] bandwidth compression technology. DoubleTalk uses "Adaptive Cancellation," a patented technology that allows the transmit and receive carriers of a full-duplex satellite link to be transmitted in the same transponder space.

The CDM-600/L modems are open network Satellite Modems that feature a range of interfaces, data rates and the industry's most bandwidth-efficient forward error correction, Low Density Parity Check. Also supported with the CDM-600/L Satellite Modems are two variants of Drop and Insert for cellular backhaul, which provide the flexibility to transmit/receive fractional parts of a T1 or E1 data stream.

"The exceptional link performance provided by the Comtech EF Data equipment will enable the cellular network provider to cost-effectively expand into remote areas that may have previously been cost-prohibitive," said Fred Kornberg, President and Chief Executive Officer of Comtech Telecommunications Corp.

Comtech EF Data Corp. manufactures a broad spectrum of satellite communications products, including Satellite Modems, Bandwidth & Capacity Management, TCP/IP Performance Enhancement Proxies, Encapsulators, Receivers, Converters, Amplifiers, Transceivers and Terminals. All products meet or exceed the standards published by worldwide and regional satellite networks. Please visit www.comtechefdata.com for more information.
