Purpose

The Cisco uBR10012 router provides data and Voice over IP (VoIP) services to cable modems (CMs) and customer premises equipment (CPE) devices over a cable TV (CATV) network, supplying high-speed Internet and voice connectivity over the coaxial cable that provides TV and other signals. Many of the Cisco uBR10012 modules are available in redundant configurations, so that the failure of one module does not affect systems operations. This guide provides troubleshooting steps for a failed component that you can take before system failure occurs and before intervention from higher level support agencies becomes necessary.

Audience

To benefit from this guide, you must be experienced using Cisco IOS and have some responsibility for installing, configuring, or operating the Cisco uBR10012 router. Knowledge of basic cable data network operations and of the Data-Over-Cable Service Interface Specifications (DOCSIS), which define the transmission of data and other services over a coaxial cable TV network.
