UDS1-BD (UDS1 Interface Circuit Pack)
Issue 1 June 2005 2433
Minor Alarm Inquiry Test (#143)
The Minor Alarm Inquiry test is used to determine if the received DS1 bit error rate is greater
than 1/1,000,000 and less than 1/1000. When D4 framing mode is selected, the UDS1 Interface
circuit pack takes 41 minutes to recognize and report a Minor alarm and 41 minutes to
recognize and report that a Minor alarm condition has cleared. If ESF framing mode is selected,
the UDS1 Interface circuit pack takes 10 minutes to recognize and report a Minor alarm and 10
minutes to recognize and report that a Minor alarm condition has cleared.
When the UDS1 Interface circuit pack detects a Minor alarm condition, it sends a
MINOR-ALARM message to the maintenance software. After the maintenance software
receives a MINOR-ALARM message, the Minor Alarm Inquiry test is initiated to confirm the
Minor alarm. Every trunk or port on the circuit pack is kept in the in-service state after the Minor
alarm is confirmed. The Minor Alarm Inquiry test runs every 10 minutes until the Minor alarm is
cleared.
0NO
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.
1. Verify that the board’s translations are correct. Execute add ds1
location to administer the UDS1 interface if it is not already
administered.
2. If the board was already administered correctly, check the error log
to determine whether the board is hyperactive. If so, the board is
shut down. Reseating the board will re-initialize it.
3. If the board was found to be correctly inserted in step 1, enter
busyout board location.
4. Enter reset board location.
5. Enter release board location.
6. Enter test board location long.
This should re-establish the linkage between the internal ID and the port.
