Cisco uBR7100 Series Universal Broadband Router Software Configuration Guide
OL-2238-03
Preface
Audience
Audience
This guide is intended for system administrators and support engineers who configure and maintain the
Cisco uBR7100 series router. Many different delivery models exist for Cisco uBR7100 series
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.
How the MSO and ISP divide responsibilities depends on the service model. In some cases, the MSO
maintains and operates the cable plant and attached CMs and STBs, and 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. The guide assumes administrators are familiar
with Cisco uBR7100 series hardware, DOCSIS or EuroDOCSIS requirements, and networking.
