6 Avaya MultiVantage Software-Controlled Maintenance:
channels in an appropriate ISDN service state (as when none are administered or they are all out of
service).
Note:
As is the case with Test #256 for an ISDN trunk, a PASS only indicates that a message was composed
and sent to the far-end switch or terminal adapter. The ISDN PRI Specification allows up to 2 minutes
for a response. Check the Error Log for ISDN-SGR (ISDN-PRI Signaling Group) errors of type 2305
for evidence of a Remote Layer 3 Query failure.
Tests #639 and #636 check the health of the D-channels and DS1 Interface Media Modules. This test
goes one step further by checking the communication path from the processor, and on to the far-end
switch or terminal adapter. A special ISDN message is sent to the far-end switch or terminal adapter,
which must respond within a specified amount of time. This test is designed to ensure that the
communication path between the switch and the far-end is up and operational, and that the two
endpoints can properly exchange ISDN control messages.

The service state can be displayed by using the status trunk <trunk
group/trunk member> or status pri-endpoint command.
Description/ Recommendation
There are no associated B-channels in an ISDN "in-service" or
"maintenance" service state. This is a NORMAL ABORT.
Administer or release an ISDN trunk or PRI endpoint before retrying
the test. For an ISDN trunk, use the status trunk group#/member#
command to verify the ISDN trunk state. For a PRI endpoint use
status pri-endpoint extension. Then, retry this test when at least
one B-channel is in the "in-service" or "maintenance" states.
The signaling channel is down. Therefore, no messages can be sent
to the far-end switch or terminal adapter.
Examine the results of Tests #636 and #639 and follow
recommendations provided there.
Could not allocate the necessary system resources to run this test.
Retry the command at 1-minute intervals a maximum of 5 times.
Internal system error OR Administration Problem
Determine if any B-channels are administered. If there are none,
then this is a normal ABORT, since this test cannot run unless at
least one B-channel is administered. If at least one B-channels is
administered, there is an internal system error. Retry the command
at 1-minute intervals a maximum of 5 times.
Internal system error. See description of ABORT with error code
2500.
