Design Considerations
This section helps you prepare for deploying the Cisco 2x2 Remote-PHY solution.
Prerequisites
-
Ensure that a digital optical network is deployed between the Cisco GS7000 node and Cisco CMTS. The supported digital optical network is Metro Ethernet.
-
Ensure that the data path is guaranteed between the Cisco CMTS and the Cisco GS7000 node.
-
Reserve sufficient bandwidth for the DOCSIS traffic.
-
Network must support IPv4 multicast forwarding.
-
Ensure that the maximum latency is as low as possible.
-
Based on the input type in the network, deploy or use the appropriate type of R-PHY device. For optical input, deploy the Cisco GS7000 node with the FRx.
