How To Deploy the Cisco Remote-PHY Solution Cisco Remote-PHY Solution Deployment 2 Design Considerations 2 Network Architecture 2 Network Topologies 3 Network Cables 3 Revised: May 25, 2017, Cisco Remote-PHY Solution Deployment Design Considerations This section helps you prepare for deploying the Cisco 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. Network Architecture The Cisco Remote-PHY solution supports the Single Controller Sharing architecture. In this architecture, multiple Cisco GS7000 equipments share the downstream and upstream channels of a Cisco RF line card in a cisco cBR chassis.
