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.
