1 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. 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. 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.
2. 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, then 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 CI card A (that is, 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, issue the test synchronization r 4 command to
clear the alarm. If any test repetitions fail, follow the procedure
for those failures.
