ATM-SGRP (ATM Signaling Group)
Issue 4 May 2002 10-225 555-233-123
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 ATM-SGRP errors of type 2305 for evidence of a Remote Layer 3 Query
failure.
Test #636 checks the health of the D-channels and ATM Interface Circuit Packs.
This test goes one step further by checking the communication path from the
processor, through the TDM/Packet Bus and ATM Interface circuit pack, 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.

Result Description/Recommendation
1006 ABORT There are no associated B-channels in an ISDN “in-service” or
“maintenance” service state. This is a NORMAL ABORT.
1. Administer or release an ISDN trunk or PRI endpoint before
retrying the test. For an ATM trunk, use the status trunk
grp#/mbr# command to verify the ISDN trunk state.
2. Retry this test when at least one B-channel is in the
“in-service” or “maintenance” states.
1113 ABORT The signaling channel is down. Therefore, no messages can be
sent to the far-end switch or terminal adapter.
1. Examine the results of Tests #636 and follow
recommendations provided there.
2100 ABORT Could not allocate the necessary system resources to run this
test.
1. Retry the command at 1-minute intervals a maximum of 5
times.
