6.11 ISDN BRI STATIONS
The iDCS 500 uses an S/T type interface so if the BRI station equipment requires a U
type circuit then an NT1 must be connected between the iDCS 500 and the station
equipment. This will convert the circuit from the S/T type 4 wire interface provided by
the iDCS 500 to the U type 2 wire interface required by the station equipment. In this
case the maximum distance of the BRI station equipment from the iDCS 500 is
determined by the specifications of the NT1.
Using two pair twisted #24 AWG or #26 AWG jumper wire cross-connected any BRI
port to the BRI station equipment (or NT1), (see Figure 6-12).
For more information regarding the programming of a BRI circuit please see the
Special Applications part of the Programming section of this manual.
