Primary Signaling Link Hardware Check (#636)

Last Updated : Oct 13, 2023 |

This test runs on ISDN-SGR (ISDN-PRI Signaling Group).

For ATM-SGRP, 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.

For ISDN-SGR, the ISDN-PRI Signaling Group D-channel port depends on the health of the TN464 UDS1 Interface circuit pack or DS1 Interface Media Module on which it resides. This test will fail if there are problems with either the ISDN-PRI Primary D-channel port or the UDS1 circuit pack or DS1 Media Module. If there are problems with the ISDN-PLK (ISDN-PRI signaling link port), investigate MG-DS1 (DS1 Interface Media Module).
