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 may 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 may 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.

Administration commands
When an ISDN trunk connects two servers or switches, set the trunk options identically at both ends of
the connection, with the exception of the Trunk Hunt fields. When ISDN-PRI interfaces are used, it is
acceptable for both ends to have the Trunk Hunt fields administered as cyclical, but if one end is
administered as ascend, the other end must be administered as descend. This helps avoid the possibility
of glare conditions. When ISDN-BRI is used, the Trunk Hunt field has to be cyclical.
