Comtech Telecommunications Corp. Receives $1.3 Million in Satellite Communications Equipment Orders for GSM Backhaul Network in Africa

Business Wire, March 13, 2008

MELVILLE, N.Y. -- Comtech Telecommunications Corp. (NASDAQ: CMTL) announced today that its Tempe, Arizona-based subsidiary, Comtech EF Data Corp., received $1.3 million in orders for satellite communications equipment. The equipment will be deployed in a GSM network in Africa.

The orders include the CDM-Qx Multi-Channel Satellite Modem with DoubleTalk([R]) Carrier-in-Carrier([R]) bandwidth compression. DoubleTalk Carrier-in-Carrier is based on patented bandwidth compression technology originally developed by Applied Signal Technology, Inc. Using "Adaptive Cancellation" it allows transmit and receive carriers of a two-way link to share the same transponder space. DoubleTalk Carrier-in-Carrier is becoming the global de-facto solution for major satellite trunking/backhaul networks. It is complementary to all advances in modem technology, including advanced forward error correction and modulation techniques. As these technologies approach theoretical limits of power and bandwidth efficiencies, DoubleTalk Carrier-in-Carrier utilizes advanced signal processing techniques to provide a new dimension in bandwidth efficiency. The results for users include reduced operating expenses, increased throughput without additional transponder resources and reduced capital expenditures.

Also included in the orders are Comtech EF Data's C-Band Transceivers, which provide configuration flexibility, ease of installation and industry-leading performance typically available only with independent, solid state power amplifier and frequency converter topologies.

"Users worldwide are benefiting from the multi-dimensional efficiencies provided by our DoubleTalk Carrier-in-Carrier technology," said Fred Kornberg, President and Chief Executive Officer of Comtech Telecommunications Corp. "These orders are another example of Comtech's ability to support global telecommunications infrastructures."

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.
