378 Appendix B: ISDN Overview
Enterprise Edge 2.0 Programming Operations Guide P0911588 Issue 01
BRI hardware
The loops on the EE-BRIM S/T module can be programmed to support either
network or terminal connections. This allows you to customize your arrangement
of lines, voice terminals, data terminals and other ISDN equipment. This section
describes some basic hardware configurations for network and terminal
connections for each loop type.
Detailed wiring information for BRI and PRI network and terminal connections is
included in the Enterprise Edge Installation and Maintenance Guide.
An EE-BRIM S/T provides four loops. Each loop can be individually programmed
as:
an S reference point connection (S loop) to ISDN terminal equipment (TE), or
a T or S reference point connection (T loop or S loop) to anISDN network using
an external NT1
S reference point
The S reference point connection provides either a point-to-point or point-to-
multipoint digital connection between Enterprise Edge and ISDN terminal
equipment (TE) that uses an S interface.
S loops support up to seven ISDN DNs, which identify TE to the Enterprise Edge
system.
T reference points
The T reference point connections provide a point-to-point digital connection
between the ISDN network and Enterprise Edge.
