ISDN BRI S/T and ISDN BRI U Small Modules

You can use the ISDN BRI modules to provide backup network connectivity if the primary
interface fails. The Dial-on-Demand Routing (DDR) feature on the ISDN BRI Small Modules
enables you to configure the ISDN interface as a backup interface.
You can use the ISDN BRI U module at either the Line Termination (LT) end (that is, the Central
Office) or Network Termination (NT) end (that is, Customer Premises) of a two-wire, long-haul
connection to the PSTN.
You can use the ISDN BRI U Small Modules for either data or voice connections. You can
configure each port on the 2-port ISDN BRI U Small Module in either data or voice mode.
The ISDN BRI U module provides two ISDN BRI U interface ports, each supporting two data
timeslots. The ISDN BRI U interface provides a data bandwidth of 128 Kbps (two 64 Kbps B-
channels), and a 16 Kbps management channel (d-channel).
For voice connections, each ISDN BRI U interface provides two B-channels for voice traffic
and one D-channel for signaling.
You can use the ISDN BRI S/T Small Module only at the user end (Terminal Equipment [TE])
of a point-to-point S/T, four-wire, interior S or T link. You cannot use the ISDN BRI S/T module
as the NT end of an S/T link, or in passive bus or star applications. Terminating resistors are
fixed on the module and cannot be removed.
You can use the ISDN BRI S/T Small Modules for either data or voice connections. You can
configure each port on the 2-port ISDN BRI S/T Small Module in either data or voice mode.
The ISDN BRI S/T module provides two ISDN BRI S/T interface ports, each supporting two
data timeslots. The ISDN BRI S/T interface provides a data bandwidth of 128 Kbps (two 64
Kbps B-channels), and a 16 Kbps management channel (d-channel).
For voice connections, each ISDN BRI S/T interface provides two B-channels for voice traffic
and one D-channel for signaling.
