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. 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 are no DS1-BD errors OR after resolving all
DS1-BD errors, issue the test synchronization r 4
command to determine if the alarm is still present. If all
repetitions of the tests pass, the alarm no longer exists.
Otherwise, 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 a CI card B (the right CI card). If
there is a red LED, 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, proceed to Step 3.
2. Otherwise, issue the test synchronization r 4 command
to clear the alarm. If any test repetitions fail, follow the
procedure for those failures.

3. Look for DS1-BD (DS1 Interface Circuit Pack) errors
using the display error command. Refer to the DS1-BD
Maintenance documentation for recommended strategy
to resolve any DS1-BD errors found. If there are no
DS1-BD errors, proceed to Step 5.
4. After all DS1-BD errors have been resolved, determine if
the alarm still exists by issuing the test synchronization
r 4 command to clear the alarm. If any test repetitions fail,
follow the procedure for those failures.
5. Check the DS1 reference A connections to the Stratum 3
clock.
6. Determine if the alarm still exists by issuing the test
synchronization r 4 command to clear the alarm. If any
test repetitions fail, follow the procedure for those failures.
If the problem persists after you have performed this
procedure three times, follow normal escalation
procedures.
