FAIL

Reference B failed or CI card B 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. If there were no DS1-BD errors or if every DS1-BD error has been 

resolved, enter test synchronization r 4 to determine whether 

the alarm is still present. If every repetition of the test passes, the 
alarm no longer exists. Otherwise, the system technician should be 
dispatched with a spare CI card to perform the following instructions 
on-site.

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

1. Look for a red LED on a CI card B (the CI card on the right). 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, proceed to step 3.

2. Otherwise, enter test synchronization r 4 to clear the alarm. If 

any test repetitions fail, follow the procedure for those failures.

3. Enter display errors and look for DS1-BD errors. If there are any, 

see 

on page 978. If there are no 

DS1-BD errors, proceed to step 5.

4. After every DS1-BD error has been resolved, determine whether the 

alarm still exists with test synchronization r 4. If any test 

repetitions fail, follow procedures for those failures.

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

6. Determine whether the alarm still exists with test 

synchronization r 4 to clear the alarm. If any test repetitions fail, 

then follow procedures for those failures.
