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.
