5.3.12 Assignment of Services Screen
Some carriers support call-by-call service selection in their ISDN PRI offerings. This 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).
If call-by-call service selection is not supported by the carrier or not required for the user’s
applications, then there is no need to assign service to a D channel.
Figure 5-19 shows the Services screen and the assignment of two mythical services
(MASTERPIECE and BUSINESS PLAN) to D channel #1. The service codes of “01” and
“02” were assigned by the carrier to these services. Remember to Save your work before
returning to the top level D channel configuration screen.
(Pressing the Clear command will erase all Service entries for the highlighted D channel.)
