Subscriber-end Overview

Subscriber-end 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 (CPE) devices at a subscriber site to the service provider hybrid fiber-coaxial (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 IOS software image stored in 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) 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 WAN data connectivity in a variety of configurations.

Cisco IOS Software Feature Sets

This section briefly describes the common feature sets supported by the Cisco uBR900 series cable access routers. Each feature set contains a number of features that provide a specific functionality such as VoIP or virtual private network (VPN) access.

The following feature set categories are currently available:

•Data operations

•Data and voice operations

The data and voice feature sets add VoIP support to the same base features contained in the data only feature sets. Telephones that are connected to the Cisco uBR924 cable access router can make voice calls over the Internet using either the H.323 (gateway/gatekeeper) voice control protocol or Simple Gateway Control Protocol (SGCP). (For more information on these protocols, refer to the “H.323 Protocol Stack” and “SGCP Protocol Stack” sections in this chapter.)

Because voice calls are real-time traffic, the Cisco uBR924 cable access router supports the DOCSIS QoS enhancements to give higher priority to IP packets containing voice traffic.

Note Voice features are available only on the Cisco uBR924 cable access router.

Note Feature sets and software images vary depending on the cable access router model you are using and the Cisco IOS software release that is running. For a list of the available software images for your application, and the specific features contained in each image, refer to the release notes for the Cisco uBR900 series cable access router and Cisco IOS software release you are using.
