Chapter 1 Solution Overview Solution Key Features Out of Scope For information on edge QAM device installation and software configuration, refer to the vendor's edge QAM device documentation. The Cisco Cable Wideband Solution-related information in this document pertains to the components listed in "In Scope" section above. Not included in the scope of the Cisco Cable Wideband Solution are the hardware and software components that make up the remainder of the cable data network. For the Cisco Cable Wideband Solution, Release 1.0, cable network management tools and operations support system (OSS) facilities for wideband cable are outside the scope of the solution. Solution Key Features The Cisco Cable Wideband Solution, Release 1.0, provides the following key features: • Pre-DOCSIS 3.0 version of wideband cable that uses packet bonding • Channel-bonded wideband downstream channels • Traditional DOCSIS 2.0 upstream channels • Solution can be deployed in parallel with DOCSIS 1.X/2.0 technology. • Existing Cisco uBR10012 router (CMTS) can be upgraded to wideband CMTS with add-on components. • Modular CMTS architecture makes use of external edge QAM devices. • Cisco uBR10012 router (CMTS) supports up to two Wideband SPAs in a Wideband SIP jacket card. • Each Cisco Wideband SPA can support up to 24 downstream RF channels. • Each Cisco Wideband SPA can support up 12 logical wideband channels (bonding groups). • Cisco Wideband CMTS and line cards have built-in redundancy and resiliency features. • Scientific Atlanta and third-party edge QAM devices are tested for interoperability. • Linksys WCM300-NA, WCM300-EURO (for EuroDOCSIS), and WCM300-JP (for J-DOCSIS) wideband cable modems support the receiving of up to eight RF channels, which can be bonded into wideband channels. One traditional DOCSIS downstream channel is used for MAC management and signalling messages. • Linksys WCM300-NA, WCM300-EURO, and WCM300-JP wideband cable modems support one primary bonded (wideband) channel for unicast and multicast traffic and up to two secondary bonded channels for multicast traffic. • Scientific Atlanta DPC2505 and EPC2505 wideband cable modems support one bonded downstream channel consisting of two RF channels, and support one traditional DOCSIS downstream channel for MAC management and signalling messages. Solution Components Cisco Cable Wideband Solution, Release 1.0, consists of Cisco, Linksys, and Scientific Atlanta components that are tested, documented, and fully supported by Cisco, Linksys, or Scientific Atlanta. Also, third-party equipment, although not fully supported by Cisco, has been selected and tested for interoperability with the solution components.

Chapter 1
Solution Overview
Solution Key Features
For information on edge QAM device installation and software configuration, refer to the vendor’s edge
QAM device documentation.
Out of Scope
The Cisco Cable Wideband Solution-related information in this document pertains to the components
listed in
“In Scope”
section above. Not included in the scope of the Cisco Cable Wideband Solution are
the hardware and software components that make up the remainder of the cable data network.
For the Cisco Cable Wideband Solution, Release 1.0, cable network management tools and operations
support system (OSS) facilities for wideband cable are outside the scope of the solution.
Solution Key Features
The Cisco Cable Wideband Solution, Release 1.0, provides the following key features:
•
Pre-DOCSIS 3.0 version of wideband cable that uses packet bonding
•
Channel-bonded wideband downstream channels
•
Traditional DOCSIS 2.0 upstream channels
•
Solution can be deployed in parallel with DOCSIS 1.X/2.0 technology.
•
Existing Cisco uBR10012 router (CMTS) can be upgraded to wideband CMTS with add-on
components.
•
Modular CMTS architecture makes use of external edge QAM devices.
•
Cisco uBR10012 router (CMTS) supports up to two Wideband SPAs in a Wideband SIP jacket card.
•
Each Cisco Wideband SPA can support up to 24 downstream RF channels.
•
Each Cisco Wideband SPA can support up 12 logical wideband channels (bonding groups).
•
Cisco Wideband CMTS and line cards have built-in redundancy and resiliency features.
•
