CH A P T E R 4 Implementing and Configuring the Solution This chapter provides implementation and configuration information for the Cisco Cable Wideband Solution, Release 1.0, and contains the following topics: • Wideband CMTS Configuration, page 4-1 • Wideband Cable Modem Behavior, page 4-6 • Supported MIBs, page 4-10 • Known Restrictions, page 4-10 Wideband CMTS Configuration This section provides overview information on the wideband CMTS configuration tasks: • Configuring Base CMTS Components, page 4-1 • Configuring Wideband CMTS Components, page 4-2 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. OL-10705-02 Cisco Cable Wideband Solution Design and Implementation Guide, Release 1.0 4-1
