2 Release Notes for Cisco uBR904 Cable Access Router for Cisco IOS Release 11.3 NA

Introduction

The Cisco uBR904 cable access router gives residential or small ofﬁce/home ofﬁce (SOHO)

subscribers, high-speed Internet or Intranet access by using a shared two-way cable system and IP

backbone network. The router connects computers and other customer premise devices at a

subscriber site to the service provider’s hybrid/ﬁber coax (HFC) and IP backbone network.

The Cisco uBR904 cable access router interoperates with any bidirectional, DOCSIS-qualiﬁed

Cable Modem Termination System (CMTS). The Cisco uBR904 ships from the Cisco factory with

a Cisco Internetwork Operating System (IOS) software image stored in nonvolatile memory

(NVRAM) that supports DOCSIS-compliant bridging or routing data operations. The Cisco

uBR904 functions as a cable modem–a modulator/demodulator at a subscriber site to convey data

communications on the cable television system.

Based on the feature licenses your company purchased, you can download other Cisco IOS images

from CCO. You can conﬁgure each Cisco uBR904 cable access router in your network to support

special operating modes based on your cable plant’s service offering and the practices in place for

your network. The Cisco uBR904 can function as an advanced router, providing wide area network

(WAN) data connectivity in a variety of conﬁgurations.
