The CDD-562L is an integrated IP demodulator that receives 2 independent L-Band channels and combines the output into a single 10/100Base-T Ethernet port for transmission onto the LAN. The demodulators and the integrated IP Module are housed in a 1RU chassis. The demodulators are designed to operate with Comtech EF Data’s IP-enabled products including modems and Performance Enhancement Proxies.
The CDD-562L simplifies hub installations by reducing rack space and costs by providing two independent demodulators in a 1RU chassis. A bank of CDD‑562L or CDD-564/L demodulators is ideal for a star topology network consisting of a shared outbound carrier with multiple return carriers from the remote sites.
At remote sites, the CDD‑562L or CDD-564/L enables mesh connectivity between multiple sites. Operating in mesh topology with direct links between sites eliminates double‑hop through the hub, thereby conserving bandwidth and reducing latency.
Data Encryption
The CDD-562LEN model has an optional data encryption feature. The unit supports 3xDES data decryption to prevent unauthorized access to data over the satellite link, which is configurable on a per demodulator basis.

Advanced IP Options
- Quality of Service (QoS) – The CDD-562L transparently passes the QoS prioritization established at the transmit end by the CDM-570/L-IP Satellite Modem.
- Header Compression – Reduces the bandwidth required for Voice over Internet Protocol (VoIP) by as much as 60%. Typical Web/HTTP traffic can be reduced by 10% via IP/TCP header compression. Each demodulator can be independently configured for header decompression.
- Payload Compression – Can reduce the required satellite bandwidth by up to 40%. Each demodulator can be independently configured for payload decompression.
- Vipersat Management System (VMS) – Integrates with the powerful network management tool Vipersat Management System (VMS). In addition to the traditional Monitoring and Control of the CDM-570/L-IP modems, CDD-564/L and CDD-562L demodulators, the VMS allows these devices to share bandwidth, and when needed, switch automatically to a dedicated SCPC channel.
