Trunk Group — ISDN-PRI Trunk Applications

ISDN-PRI trunk groups are defined by using the first page of the TRUNK GROUP screen. Since ISDN- PRI uses Message Oriented Signaling, the format of this screen is somewhat different from the assigned basic DS1 service.

Page 2 administers certain features that are unique to ISDN-PRI trunk groups. Screen pages 3 and 4 are only displayed if the Service Type field on page 1 is administered CBC. Screen pages 5 through 11 are used as required to assign group members.

Figure 7-70,Trunk Group Screen, Page 1 (ISDN-PRI), depicts this procedure.
