Comtech EF Data :: CDD-564 & CDD-564L Quad IP Demodulators

[larger image]

Applications
Voice, Video and Data Connectivity over Internet LAN/WAN Connectivity (Multiple Sites) Satellite News Gathering Content Distribution & Contribution Ship-to-Shore Communications Communications-on-the-Move (Land Vehicles/Trains) Network Management & Bandwidth-on-Demand (with Vipersat Management System) Mesh Connectivity The CDD-564 and CDD-564L are the first integrated quad IP demodulators, capable of receiving 4 independent 70/140 MHz or L-Band channels respectively and combining the output into a single 10/100BaseT Ethernet port for transmission onto the LAN. The 4 demodulators and the integrated IP Module are housed in a 1RU chassis. CDD-564/L is 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 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 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.

Standard Features
Static IP routing for unicast and multicast Management via SNMP, Web or Telnet IGMP v1 and v2 Support for Point-to-Point, Point-to-Multi-Point and hybrid network topologies 10/100BaseT Ethernet data interface (RJ‑45) Firmware upgrade via FTP FAST feature upgrades at the factory or in the field Front Panel LEDs for Unit Status, Stored Event and the status of each of the four receive channels Interoperable with the CDM‑570/L-IP, CDM‑IP 550, and CDM‑IP 300L

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. 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. Data Encryption – Supports 3xDES data decryption to prevent unauthorized access to data over the satellite link, and is configurable on a per demodulator basis. 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.
