Wideband CMTS Configuration
This section provides overview information on the wideband CMTS configuration tasks:

This section also lists documents where you can find the detailed information needed to configure the
Cisco IOS software for the uBR10012 router components, including the components needed for the
Cisco Cable Wideband Solution, Release 1.0.
Configuring Base CMTS Components
The base CMTS is the Cisco uBR10012 router with the components needed for DOCSIS 1.x/2.0
operation. Wideband cable components can be added to the Cisco uBR10012 base system so that it can
be used as a wideband CMTS. For wideband cable operation, the configuration tasks for the base CMTS
components are similar to the configuration tasks used for DOCSIS 1.x/2.0 operation. The base CMTS
can be used as a DOCSIS 1.x/2.0 CMTS.
For wideband cable operation, one additional configuration task is required on the uBR10-MC5X20
cable interface line cards that will be used for primary downstream channels on fiber nodes. For each
fiber node, a traditional DOCSIS downstream channel is used to carry MAC management and signaling
messages, and the associated traditional DOCSIS upstream channel is used for return data traffic and
signaling. The traditional DOCSIS downstream channel used in this way is referred to as the primary
downstream channel.
