Cisco uBR7200 Series Universal Broadband Router Software Configuration Guide
OL-2239-04
Preface
Audience
Audience
This guide is intended for system administrators and support engineers who configure and maintain the
CiscouBR7200series. Many different delivery models exist for CiscouBR7200series equipment:
• In smaller networks, a single service provider manages all equipment and infrastructure.
• In larger networks, multiple service operators (MSOs) and ISPs share responsibility for
provisioning and managing the cable plant and IP network.
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 cable modems and set-top boxes (STBs). This guide assumes that administrators
are familiar with CiscouBR7200series hardware, DOCSIS or EuroDOCSIS requirements, and
networking.
Document Organization
