Feature Overview

Cisco uBR900 series cable access routers are fully-functional Cisco IOS routers and standards-based
bidirectional cable modems that give a residential or small office/home office (SOHO) subscriber
high-speed Internet or Intranet access and packet telephone services via a shared two-way cable
system and IP backbone network. Cisco uBR900 series cable access routers are based on the current
Data-Over-Cable Service Interface Specifications (DOCSIS) standards, and interoperate with any
bidirectional, DOCSIS-qualified headend cable modem termination system (CMTS).

Cisco uBR900 series routers connect computers, telephone equipment, and other customer premises
devices at a subscriber site to the service provider’s Hybrid/Fiber Coax (HFC) and IP backbone
network. Functioning as cable modems, the Cisco uBR900 series routers transport data and voice
traffic on the same cable system that delivers broadcast TV signals.

Cisco uBR900 series cable access routers typically ship from the Cisco factory with a Cisco
Internetwork Operating System (IOS) software image stored in nonvolatile memory (NVRAM). The
standard Cisco IOS software image supports DOCSIS-compliant bridging operation for data as the
default.

Based on the feature licenses purchased, other Cisco IOS images can be downloaded from Cisco
Connection Online (CCO). Each Cisco uBR900 series router in your network can then be configured
to support Voice over IP (VoIP) and/or other special operating modes based on your service offering
and the practices in place for your network. A Cisco uBR900 series device can function as an
advanced router, providing wide area network (WAN) data connectivity in a variety of
configurations.

"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
