This preface describes the objectives, intended audience, organization and terminology of this
Cisco uBR7200 Series Universal Broadband Router Software Configuration Guide. The Cisco uBR7200 series CMTS and this guide support the following Cisco IOS release trains:
For additional supported Cisco IOS release trains, refer to the Cisco uBR7200 Series Software Release Notes web page on Cisco.com.
This guide describes configuring, maintaining, and troubleshooting the Cisco uBR7200 series universal broadband routers: the Cisco uBR7223, Cisco uBR7246, and Cisco uBR7246 VXR. Cisco's Cable Modem Termination System (CMTS) solutions allow cable companies, Internet service providers (ISPs), and others to allocate channel capacity for Internet access, Virtual Private Network (VPN), and Voice over IP (VoIP) services using a broadband radio frequency (RF) cable plant.
The Cisco uBR7200 series universal broadband routers sustain downstream and upstream traffic to and from two-way Data Over Cable Service Interface Specification (DOCSIS)-based cable modems (CMs) that support 6 MHz National Television Systems Committee (NTSC) operations. For NTSC cable plants not upgraded for full two-way operations, the routers also support DOCSIS-compliant telco-return CMs. For international cable companies using 8 MHz channel widths, the Cisco uBR7200 series equipment supports Phase Alternating Line (PAL) and Systeme Electronique Couleur Avec Memoire (SECAM) channel plans to operate with EuroDOCSIS-based CMs and set top box (STB) units with integrated EuroDOCSIS modems.
This guide is intended for system administrators and support engineers who configure and maintain the Cisco uBR7200 series. Many different delivery models exist for Cisco uBR7200 series equipment:
The MSO and ISP divide responsibilities according to the service model. In some cases, the MSO maintains and operates the cable plant and attached CMs and STBs, whereas the ISP owns, operates, and maintains the regional network and IP infrastructure beyond the cable distribution hub. In other cases, the CMTS and RF customer premises equipment (CPE) are viewed as part of the networking infrastructure, and the ISP maintains control for provisioning and managing DOCSIS functionality.
 |
Note This guide considers the MSO and ISP as a single service principle with responsibility to provision and manage DOCSIS-based CMs and set-top boxes (STBs). This guide assumes that administrators are familiar with Cisco uBR7200 series hardware, DOCSIS or EuroDOCSIS requirements, and networking. |
This guide focuses on configuration of Cisco IOS software for the Cisco uBR7200 series. Table 1 summarizes the chapters and procedures in this guide.
