CDM-800 Advanced VSAT Series TDM RAN Backhaul Gateway IP Router

The Comtech CDM-800 TDM RAN Backhaul Gateway Router supports industry-leading header compression for IP traffic on a per route basis. Header compression can reduce the 40 byte IP/UDP/RTP header to as little as 1 byte. For TCP/IP, the 40 byte header is reduced to as little as 3 bytes. For applications such as VoIP, header compression can provide bandwidth savings exceeding 60%. E.g. 8 kbps G.729 voice codec requires 24 kbps of IP bandwidth once encapsulated into an IP/UDP/RTP datagram. With header compression, the same voice call needs about 8.5 kbps – a saving of almost 65%.

Comtech EF Data’s Advanced VSAT Solutions portfolio provides high-performance satellite-based communication solutions for a diverse range of applications, including maritime and offshore communications, mobile backhaul with RAN optimization, IP trunking and backhaul, corporate and enterprise networks, emergency and disaster recovery. Incorporating advanced technologies developed by Comtech EF Data, AHA Products Group, Memotec and Stampede, the solutions provide unmatched performance, industry-leading bandwidth efficiencies and network optimization – while minimizing Total Cost of Ownership.

Designed for use at the hub site, CDM-800 receives the optimized DVB-S2 baseband frames from CTOG-250 for transmission over the satellite.
