Product Description

Turbo Product Coding

The Comtech Vipersat CDM-570/570L incorporates a Turbo Product Codec (TPC). TPC is a FEC technique that delivers significant performance improve- ment when compared to Viterbi with concatenated Reed-Solomon. TPC simul- taneously offers increased coding gain, lower decoding delay, and significant bandwidth savings.

Header Compression

Configurable on a per route basis, Header Compression reduces the required Voice over Internet Protocol (VoIP) bandwidth by as much as 60%. Example: a G.729 voice codec operating at 8 kbps will occupy 32 kbps once encapsulated into IP framing on a LAN. Using IP/UDP/RTP Header Compression, the same traffic only needs 10.8 kbps total WAN satellite bandwidth to cross the link. Normal Web/HTTP traffic can be reduced by an additional 10% via IP/TCP Header Compression.

Payload Compression

Compressing Payload condenses the size of data frames and reduces the satellite bandwidth required to transmit across the link. Configurable on a per route basis, Payload Compression optimizes traffic and reduces bandwidth up to 40%.

Quality of Service

The CDM-570/570L supports multi-level QoS that minimizes jitter and latency for real time traffic, provides priority treatment to mission critical applications, and allows non-critical traffic to use the remaining bandwidth. Three modes are available: Max/Priority, Min/Max, and Diff Serv.

Data Encryption

The CDM-570/570L provides 3xDES data encryption to prevent unauthorized access to data over the satellite link. Encryption is configurable on a per route basis
