Result Description/Recommendation
1001 ABORT The system could not allocate the necessary resources to run
this test.
1. Retry the command at 1-minute intervals a maximum of 5
times.
1005 ABORT This test aborts when it is run on a Stratum 4 system. Do not
change synchronization to Stratum 3 without consulting the
synchronization plan administrator for this switch.
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.
