Cisco cnBR 20.3 supports a range of virtualized network management microservices, diagnostic utilities, maintenance tools, operational functions, and extends integration support for external interfaces as well. The services are:

• Cable Modem Troubleshooting

  The Operations Hub allows you to collect troubleshooting information for cable modems on-demand. You can also retrieve troubleshooting information that the Operations Hub automatically collects when it detects L3 ping failure.

• Cisco cnBR Link Redundancy

  Link-redundancy protects the connection between a Cisco cnBR and a Service Provider (SP) router. When you connect a Cisco cnBR to an SP router (or uplink switch) using a 40G interface, a single link failure causes the whole service to fail. With this feature, you can enable another 40G interface to provide link-redundancy.

• DOCSIS Set-Top Gateway

  DOCSIS Set-top Gateway (DSG) allows the configuration and transport of out-of-band (OOB) messaging. OOB messaging takes place between a Set-top Controller (or application servers) and the customer premise equipment (CPE).
