Isdn Trunk Group - Avaya Communication Manager Administrator's Manual

ISDN Trunk Group

This screen assigns an Integrated Services Digital Network (ISDN) trunk group that supports
the ISDN and Call-by-Call Service Selection service selection features. The trunk group
provides end-to-end digital connectivity and supports a wide range of services including voice
and non-voice services, to which users have access by a limited set of CCITT-defined, standard
multipurpose interfaces.
The ISDN trunk group can contain ISDN-PRI or ISDN-BRI interfaces. However, it is not possible
to use the two types of interfaces in the same trunk groups. The type of interface is chosen
when the trunk members are assigned to the trunk group.
When ISDN-PRI interfaces are used on ISDN trunk groups, they can also be used to support
the Wideband Switching feature. This is intended to work with the H0 (384 Kbps), H11 (1536
Kbps), H12 (1920 Kbps), and NXDS0 (128 to 1984 Kbps) data services, and to support
high-speed video conferencing and data applications.
For more information on ISDN trunk groups, see
page 488.
