DMD20-LBST Modem


DMD20-LBST Modem


The DMD20 LBST L-Band Satellite Modem breaks new ground in flexibility, operation and cost. With standards including IDR, IBS and DVB, andcovering data rates up to 20 Mbps, this 1RU duplex modem covers virtually all your Satellite IP, Telecom, Video and Internet applications.

DMD20 LBST now offers DoubleTalk® Carrier-in-Carrier® bandwidthcompression. DoubleTalk Carrier-in-Carrier, based on patented “Adaptive Cancellation” technology, 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 FEC and modulation techniques. As these technologies approachtheoretical limits of power and bandwidth efficiency, DoubleTalk Carrier-in-Carrier utilizing advanced signal processing techniques provides a new dimension in bandwidth and power efficiency.
