Primary Signaling Link Hardware Check (#636)

The ATM-SGRP Signaling Group D-Channel port d epends on the health of the

TN230X interface circuit pac k on which it resides. This test fails if there are

problems with either the ATM-DCH (D-channel port) maintenanc e object or the

TN230X circuit pack. Investig ate the ATM TN230X circuit pack (ATM-TRK)

anytime there are problems with the ATM D-channel port (ATM-DCH).

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 p hysical 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.
