DMD20 & DMD20 LBST Now With DoubleTalk® Carrier-in-Carrier® |
DoubleTalk Carrier-in-Carrier bandwidth compression is now offered in two more modems, the DMD20 Universal Satellite Modem and the DMD20 LBST L-Band Satellite Modem. 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 approach theoretical limits of power and bandwidth efficiency, DoubleTalk Carrier-in-Carrier utilizing advanced signal processing techniques provides a new dimension in bandwidth and power efficiency.

CDM-750 Advanced High-Speed Trunking Modem |
|
The CDM-750 is the first modem to combine DVB-S2, Adaptive Coding and Modulation (ACM) and DoubleTalk Carrier-in-Carrier technologies. This new trunking modem provides efficiencies and throughput that will benefit even the most demanding point-to-point and backhaul links.
The CDM-750 was designed with the needs of telco operators and Internet Service Providers (ISPs) in mind. The innovative, high-performance architecture allows efficient networking and transport over satellite links for a variety of applications, such as IP trunking, G.703 trunking, high speed content delivery, disaster recovery and emergency communications.

E1 RAN Optimization |
|
The RAN Optimization technology significantly reduces the WAN (satellite) bandwidth required to carry an E1 bearer used for cellular backhaul. It provides the user complete control over the desired level of optimization and link quality. Depending on the traffic profile, typical bandwidth reduction of 30-35% can be achieved with little or no impact to the voice quality. The WAN bandwidth can be reduced by as much as 60% relative to the ingress data rate, allowing users to achieve desired bandwidth savings and voice quality. CDM-570/L-IPEN provides usage statistics to assist with link monitoring.
The CDM-570 Satellite Modem product family now offers point-to-point RAN Optimization as an option.

VersaFEC® Adaptive Coding & Modulation (ACM) |
|
With the new CDM-625 version 1.4.0, the recently released VersaFEC next generation forward error correction now supports a patent pending Adaptive Coding and Modulation (ACM) mode of operation. VersaFEC was specifically designed to provide maximum coding gain at the lowest possible latency for Constant Coding and Modulation (CCM) and ACM modes of operation. Since VersaFEC uses a constant number of symbols per frame (as opposed to DVB-S2, which uses a constant number of bits per frame), VersaFEC ACM provides a significant reduction in system latency compared to DVB-S2 ACM.
