Primary Signaling Link Hardware Check (#636)
The ATM-SGRP Signaling Group D-Channel port depends on the health of the
TN230X interface circuit pack on which it resides. This test fails if there are
problems with either the ATM-DCH (D-channel port) maintenance object or the
TN230X circuit pack. Investigate the ATM TN230X circuit pack (ATM-TRK)
anytime there are problems with the ATM D-channel port (ATM-DCH).
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.

Description/Recommendation
ABORT Internal system error
Retry the command at 1-minute intervals a maximum of 5 times.
8 FAIL There is a problem with the ATM TN230X Circuit Pack or the ATM
Signaling Channel (D-Channel), preventing any ISDN trunk calls until the
problem is resolved.
1. Consult the procedures for the TN230X Circuit Pack (ATM-TRK) and
the ATM D-channel (ATM-DCH).
PASS The basic physical connectivity of the D-channel is intact and functional.
1. Try this test repeatedly to ensure the link is up and to uncover any
transitory problems.
