Document Objectives

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.
