DS1-BD (DS1 Interface Circuit Pack)
Table 8-250. Test #143 Minor Alarm Inquiry Test — Continued
Error Test
Code Result Description / Recommendation
PASS No Minor alarm is detected in DS1 Interface circuit pack.
0 NO The test could not relate the internal ID to the port (no board).
BOARD
This could be due to incorrect translations, no board is inserted, an incorrect
board is inserted, or an insane board is inserted.
1. Verify that the board's translations are correct. Use the add ds1 UUCSS
2. If board was already administered correctly, check the error log to
3. If the board was found to be correctly inserted in step 1, issue the busyout
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
Slip Alarm Inquiry Test (144)
Slips occur when transmitter and receiver are not running at precisely the same
clock rate. The DS1 Interface circuit pack can detect both positive and negative
slips on the DS1 facility. The Slip Alarm Inquiry test is used to acquire the total
number of slips occurred on a DS1 link.
When the DS1 Interface circuit pack detects a slip condition, the circuit pack will
increase the on-board slip counter by 1. A SLIP-COUNT message is
spontaneously sent to the system software after the counter reaches a threshold
(for example, 88). When the maintenance software receives the SLIP-COUNT
message, the Slip Alarm Inquiry test is initiated to query the slip counters on DS1
Interface circuit pack and total the slip counts in the maintenance software.
If the count of slips is over the threshold, a Minor alarm is raised against the DS1
Interface circuit pack. All trunks of the DS1 Interface circuit pack are still in the
in-service state. If the DS1 Interface circuit pack is used to supply the system
synchronization source, the MINOR alarm will initiate a synchronization source
switch. See "TDM-BUS" and "SYNC (Synchronization)" for details.

determine whether the board is hyperactive. If so, the board was shut
down. Reseating the board will re-initialize it.

This should re-establish the link between the internal ID and the port.
