Testing Service Availability
The following explains how to test the availability of
telecommunications services for ISDN calls.
You can check that an individual bearer service or
teleservice is available by connecting a call using that
service. However, when you need to check the
availability of more than one ISDN teleservice, the
quickest and easiest method is to perform a Service Test.
How the Service Test Works
The Service Test checks the ISDN services subscribed to
on the line under test, and tells you which ones are
available. It does this by initiating a series of calls which
use all of the bearer capabilities for the current protocol,
in turn. A call is made on the selected B channel for each
of the supported bearer capabilities, Higher Layer
Compatibility or Service Indicator Code values.
When the test is complete, the results indicate which
services the link is configured to carry. Service test results
are stored even when aurora
