Comtech Telecommunications Corp. Announces $1.0 Million in Orders for New High-Speed Trunking Modem

Wednesday, Jul 28, 2010

Comtech Telecommunications
Corp. (Nasdaq:CMTL) announced today that its Tempe, Arizona-based
subsidiary, Comtech EF Data Corp., has received $1.0 million in orders for
its new CDM-750 Advanced High-Speed Trunking Modem. The modems are being
deployed by a leading operator of cellular telecommunications services in
Southeast Asia to support high-speed GSM/IP trunking backhaul. By using the
CDM-750, this operator will enable links of approximately 90 Mbps in 15.5
MHz of bandwidth, which is spectrally equivalent to running at 64-QAM over
satellite.

The CDM-750 Advanced High-Speed Trunking Modem simultaneously supports
DVB-S2, Adaptive Coding and Modulation (ACM) and the award-winning
DoubleTalk(R) Carrier-in-Carrier(R) bandwidth compression. Leveraging the
DVB-S2 EN 302 307 LDPC/BCH standard, the CDM-750 provides a blend of coding
and forward error correction (FEC) to ensure that the maximum amount of
satellite traffic is transported for a given signal to noise capacity. With
its ACM support, it can respond to changing link conditions by automatically
adjusting modulation and FEC rates and converting link margin into user
capacity under all conditions.
Additionally, the DoubleTalk(R) Carrier-in-Carrier(R) technology allows the
transmit and receive carriers of a full-duplex satellite link to be
transmitted in the same transponder space. When combined with advanced FEC
and modulation techniques, DoubleTalk(R) Carrier-in-Carrier(R) can deliver
unprecedented operating expense savings.

"I am excited about the tremendous capabilities of this new modem and its
potential in the market place. Due to exceptional performance in customer
trials, these orders were awarded only months after the product's release,"
commented Fred Kornberg, President and Chief Executive Officer of Comtech
Telecommunications Corp. "By using the new CDM-750 Advanced High-Speed
Trunking Modem, this operator can maximize satellite resources and realize
significant OPEX savings."
