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) MO 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

ABRT

Internal system error

1. Retry the command at 1-minute intervals up to 5 times.

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.
