Description / Recommendation
ABRT The system could not allocate the necessary resources for the test
1. Wait 1-minute, and retry the test.
1001 ABRT The system could not allocate the necessary resources for the test.
1. Wait 1-minute, and retry the test.
255 ABRT The test was not executed because the IPSI or Processor/Tone-Clock
circuit pack was using its local oscillator rather than synchronizing to an
external source.
1. Verify that this IPSI or Processor/Tone-Clock circuit pack is expected to
be the synchronization source. If not, correct the synchronization
information and re-execute the test.
2000 ABRT Response to the test request was not received within the allowable time
period.
1. Retry the command at 1-minute intervals up to 5 times.
2100 ABRT System resources required to run this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
Any FAIL The Error Code represents the rate (in Parts Per Million, or PPM) at which
clock slip errors have been detected on the incoming synchronization
source since the last PPM inquiry was sent to the IPSI or Processor/
Tone-Clock circuit pack. A failure of this test indicates that we are outside
of (
S8700 MC: Stratum-3) or Stratum-4 timing specifications on the incoming
timing source.
The Error Code is a variable amount ranging from 1 to 254.
1. If error 1537 is entered in the hardware error log against TDM-CLK,
then the board has switched timing sources. Follow the procedures
associated with hardware log Error Code 1537.
2. Otherwise, see ‘‘Troubleshooting Approach’’ in the SYNC
(Port-Network Synchronization) on page 2143 section of this manual.
