Manage Cable Devices
The Cisco cBR-8 Converged Broadband Router (Cisco cBR-8) is a 13 rack unit (RU) chassis. It supports multiple card modules and is designed with back-to-back midplanes; a front facing Digital Midplane and a rear facing RF Midplane. In a cable network with the Remote PHY architecture, multiple Remote PHY Devices (RPDs) connect to Cisco cBR-8 devices based on the Data Over Cable Systems Interface Standard (DOCSIS) and EuroDOCSIS standards that define two-way operation over the cable network.
Remote PHY is an architectural strategy that removes the PHY element from a product and places that PHY element in a separate access point interconnected with an IP network. The Cisco Remote-PHY solution leverages existing IP technologies like Ethernet PON (EPON), Gigabit-capable Passive Optical Networks (GPON), and Metro Ethernet (MetroE) equipment; it deploys DOCSIS in Multi Dwelling Units (MDUs) over digital fiber to enable two-way services over cable.
Using Cisco EPN Manager, you can add and discover Cisco cBR-8 and devices and RPDs, view their L2TP links and topology on the network topology, and further configure them. You can also continuously monitor the health of RPDs to Cisco cBR-8 device links. See Manage Cisco cBR-8 and RPDs Association.
Cisco EPN Manager, enables you to create service definitions with profiles such as events profiles, downstream and upstream controller profiles, to associate the definitions with RPDs in bulk. As part of the service definition, you can also configure the Remote PHY timing values for the RPD, using the Remote DTI (R-DTI) protocol. To configure the R-DTI profile and other service definition parameters, see Manage RPD Service Definitions.

The process of managing cable devices in Cisco EPN Manager involves:
-
Ensuring that the cBR-8 devices and Cisco Smart PHY are up and available for configuring.
-
Configuring the required access in Cisco EPN Manager by providing Cisco Smart PHY credentials.
-
Adding the cBR-8 device and ensuring that the inventory collection status for the device is 'Completed'. See Add Devices to Cisco EPN Manager
-
Adding RPD information to Cisco EPN Manager either manually or by importing RPD details from a CSV file.
-
Ensuring that the status of CBR-8 and RPD pairing is Online.
-
(Optional) Creating service definitions or using the default service definition and applying them to the RPDs.
-
(Optional) Monitoring the devices using the network topology to view the alarm and link information.
-
(Optional) Managing device images using Software Image Management. See Manage Device Software Images.
