Figure 1-2
illustrates the CDD-880 Multi Receiver Router as deployed in a typical satellite-based
communications network – in this example, a Hub-and-Spoke IP Network.
The CDD-880 Multi Receiver Router features six plug-in cards, each of which supports two
VersaFEC/Streamline demodulators. This allows for six deployed configurations: 2, 4, 6, 8, 10
and 12 demods.
Overall, the receive path allows IP packets to be Streamline decapsulated, K4 decompressed if
required, and then sent to the processor. IP packets are sent out the appropriate Ethernet interface.
Optimized E1 packets will be received with IP/UDP headers and routed to the appropriate
CXU-810 RAN Optimizer on the hub network.
Note: As IP/UDP packets, the CDD-880 is completely agnostic/ignorant to the RAN
Optimization feature, which offers significant network feature simplicity advantages.
The CDD-880 receive path has the following characteristics:
• 256 IPv4 static routes
• 256 Static ARP entries
• Streamline-compatible decapsulation
• VersaFEC compatible for all MODCODs
• (FUTURE) Header decompression
• The receive path is compatible with a CDM-840 for all features
• Routing Only (no bridge mode)
