Configuring the Cisco 2x2 Remote-PHY Solution

Prerequisites for Configuring the Cisco 2x2 Remote-PHY Solution

  • The Cisco CMTS must have at least one DOCSIS Timing, Communication, and Control (DTCC) card configured in the DOCSIS Timing Interface (DTI) mode for the Cisco cBR RF line card to work with the Cisco GS7000 node.

Restrictions for Configuring the Cisco 2x2 Remote-PHY Solution

  • Adding or removing the upstream or downstream channels in the channel group may trigger the Cisco GS7000 to reset.

  • The Cisco cBR RF line card supports only static DEPI configuration.

  • The Cisco cBR RF line card does not support Spectrum Management, Inter Line Card RF Spanning, and High Availability.

How to Configure the Cisco 2x2 Remote-PHY Solution

For detailed instructions, see the Cisco 2x2 Remote-PHY Configuration Guide.
