Comtech Telecommunications Corp. Receives $1.8 Million Order for Modems with DoubleTalk® Carrier-in-Carrier® to Support Military Network Expansion

May 7, 2012--Comtech Telecommunications Corp. (NASDAQ: CMTL) announced today that its Tempe, Arizona-based subsidiary, Comtech EF Data (News - Alert) Corp., received a $1.8 million order from a government systems integrator for modems with DoubleTalk^® Carrier-in-Carrier^® bandwidth compression. The U.S. military will utilize the modems in deployable terminals to support a satellite-based network expansion for battlefield communications.

The order specified the DMD2050 MIL-STD-188-165A Compliant Universal Satellite Modem. The DMD2050 supports the widest possible range of U.S. government and commercial standards. It provides highly advanced and bandwidth-efficient forward error correction and a complete range of modulation types. Given the U.S. government's IP-centric focus, advanced options for the DMD2050 were included in the order including DoubleTalk^® Carrier-in-Carrier^® bandwidth compression and Low Density Parity Check ("LDPC") forward error correction.

DoubleTalk^® Carrier-in-Carrier^®, based on Raytheon Applied Signal (News - Alert) Technology's patented "Adaptive Cancellation" circuitry, allows transmit and receive carriers of a duplex link to share the same transponder space. DoubleTalk^® Carrier-in-Carrier^® is complementary to all advances in modem technology, including advanced forward rror correction and modulation techniques. As these technologies approach theoretical limits of power and bandwidth efficiencies, DoubleTalk^® Carrier-in-Carrier^®, utilizing advanced signal processing techniques, provides a new dimension in bandwidth efficiency. When combined with LDPC, it will provide unprecedented savings in transponder bandwidth and power utilization for the U.S. military. This will enable successful deployments in both bandwidth-limited and power-limited environments.

"The U.S. military is currently utilizing our DMD2050 modems to support mission-critical communications," said Fred Kornberg (News - Alert), President and Chief Executive Officer of Comtech Telecommunications Corp. "Based on the field-proven performance and bandwidth efficiencies, the newly ordered modems will seamlessly support the U.S. military's network expansion."
