Configuring ISDN Features
Another example of this procedure is shown in Figure 6-18. If you want a single incoming
trunk group to be routed to only one outgoing trunk group, D channel #1, trunk group “A” is
routed to D channel #2, trunk group “B.” The alternate routes 2-3 must contain the same
information in alternate route #2. Since this is the only alternative route, if that route is busy,
the unit will drop the call.

Assignment of Services
Some carriers support call-by-call service selection in their ACS-PRI/BRI offerings. This
feature allows users to select a different service (and, usually, a different billing rate) for each
call placed.
feature allows users to select a different service (and, usually, a different billing rate) for each
call placed.
If call-by-call service is supported, users must tell the system which service(s) is/are supported
by each D channel, and what the code is for each service. The carrier will supply a service code
for each supported service. The Service format code is always two digits, a space and the
name of the service. When placing a call using call profiles, only valid service codes will be
allowed (see Call Profiles below for additional information about services).
