ATM-SGRP (ATM Signaling Group)
Issue 1 May 2002
8-261555-233-143
Layer 2 Status Test (#647)
The Layer 2 Status test checks the layer-2 status of the ATM-SRG signaling
channel (D channel). This test fails when:
there is a hardware failure
there is a facility problem
the D channels are not administered correctly
The Signaling Link Hardware Check (Test #637) and the Remote Layer 3 Query
test (#1291) detects most problems caused by hardware failures or incorrect
administration.

Result Description / Recommendation
1132 ABORT Internal system error. The port location for the D channel is not known. This
condition should not be possible since an administered ATM circuit pack must
be specified when a Signaling Group is administered:
1. Retry the command at 1-minute intervals up to five times.
1134 ABORT Internal system error. The associated ATM circuit pack is not administered.
This condition should not be possible, since an administered ATM circuit pack
must be specified when administering a Signaling Group.
1. Retry the command at 1-minute intervals up to three times.
2500 ABORT Internal system error
1. Retry the command at 1-minute intervals up to five times.
1 FAIL Layer 2 of the signaling channel is down.
1. Examine the results of the Signaling test (#636), and follow
recommendations provided there.
2. If Test #636 (Primary Signaling Link Hardware Check) passes, the Layer 2
Query test may still fail if the signaling channel at the far end has not been
administered correctly or if the signaling channel has been busied out.
3. Verify that the far-end signaling channel (D channel) has been
administered correctly.
4. Verify that the ATM-DCH port used for the D channel has not been busied
out at the far end.
