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).

ABORT Internal system error
Retry the command at 1-minute intervals up to 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.
