Loss of Signal Alarm Inquiry Test (#138)<br />

If a Loss Of Signal alarm and an I-CSU/Sync Splitter error coexist, the Loss Of Signal alarm<br />

condition takes priority, and the board and all of its trunks are put in the out-of-service state.<br />

Errors are logged for both.<br />

When the system receives notification that the I-CSU/Sync Splitter hardware error condition no<br />

longer exists, maintenance restores the board and its trunks to their previous service state if the<br />

alarm can be cleared (no other I-CSU/Sync Splitter errors or Loss Of Signal alarms exist).<br />

Description / Recommendation<br />

ABORT Internal system error<br />

1. Retry the command at 1-minute intervals up to 5 times.<br />

2000 ABORT Response to the test was not received within the allowed time. This may<br />

be due to hyperactivity.<br />

1. Enter display errors on the SAT.<br />

2. Check for Error Type 1538 for this DS1 board. If Error Type 1538<br />

appears in the error log for this board, see Hyperactive DS1/UDS1<br />

Interface Circuit Pack/Media Module for the repair procedures.<br />

Otherwise, retry the test at 1-minute intervals up to 5 times.<br />

2100 ABORT Could not allocate the necessary system resources to run this test.<br />

1. Retry the command at 1-minute intervals up to 5 times.<br />

FAIL The board detects a Loss of Signal alarm. The physical link is broken or<br />

the remote DS1 endpoint is down. All trunks or ports of this board are<br />

out-of-service.<br />

Note:<br />

a DS1/UDS1 circuit pack is designated as the supplier of<br />

the system synchronization source, the system<br />

synchronization maintenance adopts a source elsewhere.<br />

network facility or to another switch, see T1 Network Facility<br />
