FAIL

Either Reference A failed or CI card A failed. This condition usually 
indicates a failure of the DS1 reference; however, there may also be a 
failure of the CI card to which the reference is connected. The system 
technician dispatched to investigate this problem should take a spare CI 
card in case the CI card caused the failure. 

If you are NOT ON-SITE, use the following procedure:

1. Use display errors to look for DS1-BD (DS1 Interface Circuit 

Pack) errors. See the DS1-BD Maintenance documentation for 
recommended strategy to resolve any DS1-BD errors found.

2. If there are no DS1-BD errors or after resolving every DS1-BD error, 

use test synchronization r 4 to see if the alarm still exists. If 

every test repetition passes, then the alarm no longer exists. 
Otherwise, the system technician should be dispatched with a spare CI 
card to use the following instructions on-site.

If you are ON-SITE, use the following procedure:

1. Look for a red LED on CI card A (i.e., the left CI card). If there is a red 

LED, then replace the CI card, if a spare is available. If no spare CI is 
available on-site, proceed to Step 3. If after replacing the CI card, the 
red LED on the new CI card lights also, then proceed to Step 3.

2. If a spare CI card is available, replace the suspect CI card. Otherwise, 

use test synchronization r 4 to clear the alarm. If any test 

repetitions fail, then follow the procedure for those failures.

3. Use display errors to look for DS1-BD (DS1 Interface Circuit 

Pack) errors. See the DS1-BD Maintenance documentation for 
recommended strategy to resolve any DS1-BD errors found. If there 
are no DS1-BD errors, then proceed to Step 5.

4. After every DS1-BD error has been resolved, use test 

synchronization r 4 to clear the alarm and see if the alarm still 

exists. If any test repetitions fail, follow the procedures for those 
failures.

5. Check the DS1 reference A connections to the Stratum-3 clock.

6. To determine whether the alarm still exists, execute the test 

synchronization r 4 command to clear the alarm. If any test 

repetitions fail, then follow the procedures for those failures.
