Comtech EF Data says that it has received a US$1.3 million order for satellite modems that will support cellular backhaul networks in Africa and the Middle East. The order includes Comtech EF Data''s CDM-QxL Multi-Channel Satellite Modems with DoubleTalk) Carrier-in-Carrier and the CDM-570L Satellite Modems with IP Modules.

The CDM-QxL is a multi-channel satellite modem that features the award-winning DoubleTalk Carrier-in-Carrier. Carrier-in-Carrier is based on Applied Signal Technology''s DoubleTalk 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. Users can reduce operating costs, increase throughput or availability without additional transponder resources, and/or reduce capital expenditures.

Fred Kornberg, President and Chief Executive Officer of Comtech Telecommunications Corp., commented, "By deploying Comtech''s bandwidth efficient solutions, cellular operators can minimize expenditures and cost-effectively expand their network coverage."
