June 28, 2012--Comtech Telecommunications Corp. (NASDAQ: CMTL) announced today that its Tempe, Arizona-based subsidiary, Comtech EF Data Corp., received a $1.3 million follow-on contract award for satellite ground equipment from an existing government customer. The order specified two models of Modems and Frequency Converters, which will be deployed to support a network expansion in Asia. The CDM-625 Advanced Satellite Modem and the CDM-700 High-Speed Satellite Modem were ordered. The CDM-625 combines advanced forward error correction with DoubleTalk ® Carrier-in-Carrier ® bandwidth compression for maximum savings. DoubleTalk ® Carrier-in-Carrier ®, based on Raytheon Applied Signal Technology's patented "Adaptive Cancellation" technology, allows transmit and receive carriers of a duplex link to share the same transponder space. The combination of advanced technologies enables users to minimize OPEX/CAPEX and maximize throughput/availability without using additional transponder resources. The CDM-700 is a high-speed modem intended for operation with a range of multi-port data interfaces. The modem operates in broadcast, circuit restoration, point-to-point and point-to-multipoint applications with exceptional power and bandwidth efficiency. Also purchased were C-Band and Ku-Band Synthesized Frequency Converters that meet or exceed industry standards, and can easily be integrated and operated in any size earth station.
