The Cisco uBR904 cable modem
also known as a Cisco IOS Universal Broadband Router has the
following features:
A Data-over-Cable
Service Interface Specification (DOCSIS) cable modem designed
for use in the small office/home office (SOHO)
This compact
device 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 cable interface requires
no configuration or setup procedures other than connecting the unit
to the cable system.
Ethernet interface configuration is provided
through a command-line interface (CLI) parser, which can be reached
either through the console port or via Telnet to the Cisco uBR904
Ethernet port.
Console and TTY sessions are supported. The CLI configuration interface, modifications will be made to
the PC ClickStart configuration utility to support Cisco uBR904
configuration.
The console CLI can also be disabled and the
configuration is then controlled solely from a downloaded file.
The Cisco uBR904 is
compatible with DOCSIS specifications, including some optional
features that are not supported by standard residential cable
modems. These optional features include quality of service (QoS), IP
tunneling, and IP routing.
