Avaya Advanced Gateway 2330 hardware components fundamentals
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 voice connections. You can configure
each port on the 2-port ISDN BRI S/T Small Module in voice mode.
The ISDN BRI S/T module provides two ISDN BRI S/T interface ports, each supporting two
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.
You can install the 2-port ISDN BRI Small Modules in any of the Small Module slots on the
AG2330 chassis.
The following figure shows the 2-port ISDN BRI S/T Small Module.
