The Cisco uBR904 cable modem is a fully functional Cisco IOS universal broadband router and an integral Data-over-Cable Service Interface Specification (DOCSIS) cable modem designed for use in the small office/home office (SOHO). It is a compact device that has the familiar features and programming interface of other routers in the extensive line of small and medium-sized business product offerings from Cisco. It provides packet data transport for TCP/IP applications between home or office computers and the cable head end. The Cisco uBR904 has a single-cable, F-connector interface for connection to the hybrid fiber coaxial (HFC) system and a built-in Ethernet 10BaseT hub, providing four RJ-45 ports to which subscriber devices can be connected. All four ports are treated as one Ethernet interface by Cisco IOS software. More hosts can be connected to the Cisco uBR904 by connecting one of the 10BaseT ports to a hub. Additionally, the Cisco uBR904 has an RJ-45 console interface for configuration and diagnostic purposes.The Cisco uBR904 provides telecommuters with secure, high-speed access to their corporate intranet and the Internet. With the integration of Cisco's industry leading IOS software incorporated into the cable modem, Cisco brings the technology powering 80% of the Internet into the home. The Cisco uBR904 offers small offices high-speed access to the Internet, security, and the ability to support multiple PCs and other IP devices in the office network. By integrating a fully functional Cisco IOS router and cable modem, the Cisco uBR904 provides small offices with the ability to support up to 100 IP devices in their local area network (LAN) environment. The Cisco uBR904 provides branch offices with secure, high-speed access to their corporate intranet and the Internet. By integrating a fully functional Cisco IOS router and cable modem, the Cisco uBR904 also provides branch offices with the ability to bring this high speed intranet and Internet connectivity to up to 100 IP devices. High-speed access between the branch office LAN, the corporate intranet, and the Internet is provided by the Cisco uBR904s' integrated cable modem. This allows the Cisco uBR904 to offer peak connection speeds of up to 10 Mb/s upstream and 40 Mb/s downstream. Using the QoS feature built into the Cisco uBR904's IOS operating system, the entire branch office can maintain this high-speed connection even during peak traffic hours.
