The CDD-564 and CDD-564L are integrated IP demodulators that receive 4 independent 70/140 MHz or L-Band channels (depending on model) and combine 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-564/L simplifies hub installations by reducing rack space and costs by providing four independent demodulators in a 1RU chassis. A bank of CDD‑564/L or CDD-562L 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‑564/L or CDD-562L 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-564EN and CDD-564LEN models have an optional data encryption feature. The units support 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-564/L 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.
