The Cisco uBR900 series cable access routers are designed to provide commercial services for cable operators, allowing them to expand their offerings for customers. The routers are based on the Data-Over-Cable Service Interface Specifications (DOCSIS)-a standard developed to ensure that any DOCSIS-certified cable modem can interoperate with any bi-directional, DOCSIS-qualified Cable Modem Termination System (CMTS).
The Cisco uBR900 series cable access routers are integrated DOCSIS 1.1-based cable modems and Cisco IOS Software routers that contain dedicated hardware for achieving high-speed IP Security (IPSec) Virtual Private Network (VPN) performance. Fully standards-based, the Cisco uBR900 series cable access routers can operate in DOCSIS bridge mode similar to any standards-based cable modem. By enabling the Cisco uBR900 series cable access router IP routing and advanced Firewall and IPSec VPN features, however, cable operators can transform these devices into powerful customer premises equipment (CPE) or enterprise devices to support small businesses, branch offices, and corporate telecommuters. You gain the benefits of a trusted router with full business-class firewall integration and a quality cable modem in one box.
The Cisco uBR900 series cable access routers support Data Encryption Standard (DES) and Triple Data Encryption Standard (3DES) VPN capabilities, widely recognized as the standards to use to ensure security and privacy in telecommunications infrastructures. The Cisco uBR900 series cable access routers contain dedicated hardware for IPSec, thereby greatly improving performance over software-based solutions.

Cisco uBR925 Cable Access Router
The Cisco uBR925 cable access router has all the features of the Cisco uBR905 cable access router, but adds support for Voice-over-IP (VoIP) and offers a 1-port Universal Serial Bus (USB) connection. The Cisco uBR925 cable access router integrates a 4-port 10BaseT Ethernet hub and 1-port USB port with Firewall and IPSec VPN technologies. The Cisco uBR925 cable access router can connect to a PC through either its Ethernet hub ports or through its USB port. If supported by the service provider, the router can connect more than one PC using both types of connections.
The Cisco uBR925 cable access router further offers two RJ-11 telephone jacks to support VoIP to transmit voice, modem, and fax calls over the TCP/IP cable network. Depending on the services the provider offers and the services the subscriber purchases, subscribers can place and receive calls without using the local exchange carrier. They can connect two single-line telephones, modems, or fax devices to each of the voice ports, or connect a dual-line telephone to the first voice port. Depending on the voice network set up by the service provider, subscribers can place calls to numbers that are in the existing telco network; the called party does not have to be using VoIP telephone service. The Cisco uBR925 cable access router provides FXS (Foreign Exchange Station) services and supports analog phones, fax devices, and modems. Subscribers can connect multiple telephones, modems, and fax devices to a single voice line. Each multiple device, however, acts as an extension to that voice line.

Cisco uBR905 Cable Access Router
The Cisco uBR905 cable access router is a data-only member of the Cisco uBR900 series cable access router family. The product integrates a 4-port 10BaseT Ethernet hub with Firewall and IPSec VPN technologies in a single, compact design. The Cisco uBR905 cable access router has been CableLabs-certified to DOCSIS 1.0 specifications
The Cisco uBR900 series cable access routers deliver feature-rich broadband access to small offices, branch locations, telecommuters, or residential customers. The products leverage many design elements from the award-winning Cisco uBR924 cable access router to provide a reliable, stable, and proven product. Similar to other Cisco cable CPE devices, the Cisco uBR900 series cable access routers use Cisco IOS Software that simplifies deployment, operations, and maintenance through common command line interface (CLI), provisioning tools, and Simple Network Management Protocol (SNMP) support. The Cisco uBR900 series cable access routers deliver a dependable and proven operating environment that protects investment through ongoing enhancements to the operating system and common provisioning and management tools.
