DATA COMMUNICATIONS-PRI
3. Programming
STEP 1: Assign the Basic Data for ISDN. (Refer to Chapter 3, “Basic Data Assignment for ISDN”.)
Note:
Pooled modems and modems connected to analog stations may be used on PRI channels when a straight
digital data connection is not required. With PRI, modem pooling will always be automatic when
accessing a PRI channel by setting the “AMND” command (Parameter A/D) to 0. If “AMND” (Parameter
A/D) is set to 1, the channel will either use modem pooling or a straight digital path depending on the
number dialed. This number is compared with the PRI link to the other end switch to determine if an
analog or digital extension is being called.
