System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. By clearing error codes associated with the Primary
Signaling Link Hardware Check, for example, you may also clear errors generated
from other tests in the testing sequence.
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).

Result 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.
