Signaling Link State Check Test (#255)

Signaling Link State Check Test (#255)

The DS1 ISDN Trunk depends on the health of the appropriate MM710 Interface Media Module. It also depends on the ISDN-PRI D-channel (ISDN-LNK) trunk. This test checks the status of those critical elements.

Table 48. TEST #255 Signaling Link State Check Test
Error Code	Test Result	Description/ Recommendation
None	ABORT	Internal system error
0	ABORT
1114	ABORT	The signaling link is in a transitional state. Retry the command at 1-minute intervals for a maximum of 5 times.
1018	ABORT	Maintenance is disable on this trunk. Enable maintenance by entering "y" in the "Maintenance Tests?" field on page 2 of the change trunk-group form.
4	FAIL	There is a problem with the signaling channel. Consult the procedures for the ISDN-PRI Signaling Group (ISDN-SGRP). Further information may also be obtained by consulting the procedures for the ISDN-PRI Signaling Channel (ISDN-LNK).
8	FAIL	There is a problem with the DS1 interface Media Module. Consult the procedures for the appropriate DS1 interface Media Module (DS1-MM).
	PASS	The signaling link hardware is OK.
Any	NO BOARD	The test could not relate the internal ID to the port (no board). This could be due to incorrect translations, no board is inserted, an incorrect board is inserted, or an insane board is inserted. Ensure that the board translations are correct. Execute the add ds1 GGGVS command to administer the DS1-MM interface if it is not already administered. If the board was already administered correctly, check the error log to determine whether the board is hyperactive. If this is the case, the board is shut down. Reseating the board will re-initialize the board. If the board was found to be correctly inserted in step 1, then issue the busyout board command. Issue the reset board command. Issue the release busy board command. Issue the test board long command. This should re-establish the linkage between the internal ID and the port.
