Design Considerations
This section helps you prepare for deploying the Cisco Remote-PHY solution.
• 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.
