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).
