Release Notes for Cisco uBR924 Cable Access Router for Cisco IOS Release 12.1(5)T

OL-0385-04 Rev. B0 (2/2001)

System Requirements

Note For releases earlier than Cisco IOS Release 12.0(5)T—not 12.1(5)T but

12.0(5)T—, the four Ethernet hub ports only support a maximum of three

computers when operating in bridging mode. (The maximum of three computers

is for all four ports together— not three computers per port).

–

One of the four Ethernet hub ports at the rear of the Cisco uBR924 router can be connected to

an Ethernet hub, which then connects additional computers or devices at the site when

operating in routing or bridging mode.

• Two RJ-11 Foreign Exchange Station (FXS) ports connect telephones and fax devices to the cable

system and IP backbone; the router ships from the Cisco factory with the voice ports enabled. The

FXS ports on the Cisco uBR924 router can be connected to analog telephones or fax machines but

cannot be used for private branch exchange (PBX) extensions.

• One RJ-11 port connects to a standard, analog telephone line (optional) to provide a backup plain

old telephone service (POTS) connection to the Public Switched Telephone Network (PSTN). The

backup port becomes operational if the Cisco uBR924 router loses power or its connection to the

cable network.

• One RJ-45 console port (optional) to connect to a laptop computer or console terminal when locally

configuring the Cisco uBR924 router; the router ships from the Cisco factory with the console port

enabled.
