Solution Description and Scope Chapter 1 Solution Overview 191347 Architecture and Scope Figure 1-1 presents a simplified view of the Cisco Cable Wideband Solution, Release 1.0. In Figure 1-1, two RF channels are bonded into a wideband channel (bonding group). The Cisco Cable Wideband Solution includes these major components: • Wideband cable modem termination system (WCMTS)-Cisco uBR10012 router • Cisco Wideband SPA (Shared Port Adapter) and Cisco Wideband SIP (SPA Interface Processor) • Edge QAM (EQAM) device • Wideband cable modem (WCM) Regional cable headend Figure 1-1 Cisco Wideband Cable System WAN WAN uBR10012 WCMTS Wideband SIP Wideband SPA GE MC5X20 cable interface line card Downstream wideband channel GE switch Edge QAM device Downstream wideband channel RF Downstream RF channel for MAC management and signaling messages Traditional DOCSIS upstream channel for return data traffic and signaling Wideband cable modem In Scope The scope of the Cisco Cable Wideband Solution, Release 1.0, comprises fully tested and supported Cisco and Scientific Atlanta components, as well as selected third-party components tested for interoperability by Cisco. The following aspects of the solution are in scope: • DOCSIS 3.0 Downstream Channel Bonding software • One or more downstream wideband channels with RF channel bonding • Wideband CMTS (Cisco uBR10012 router) including cable interface and network uplink line cards • Cisco Wideband SIP and Cisco Wideband SPA • Edge QAM device • Wideband cable modem • Wideband-related cable modem configuration file parameters • Cisco IOS command set for wideband-channel configuration, provisioning, and maintenance • Cisco IOS command set for wideband hardware monitoring, troubleshooting, and debugging • MIBs for the wideband CMTS, wideband cable modem, and wideband channel and service statistics Device configuration that is in scope for this document is limited to the Wideband SIP and Wideband SPA. Comprehensive documentation for other CMTS components is provided in the existing Cisco uBR10012 documentation set, which is accessible at www.cisco.com.
