Error
Code Test Result Description/ Recommendation
ABORT The system could not allocate the necessary resources for the test.
1001 ABORT The system could not allocate the necessary resources for the test.
1. Wait 1-minute, and retry the test.
255 ABORT The test was not executed because the Tone-Clock circuit pack was using its
local oscillator rather than synchronizing to an external source.
1. Verify that this Tone-Clock circuit pack is expec ted to be the
synchronization source. If not, correct the synchronization information and
re-execute the test.
2000 ABORT Response to the test request was not received within the allowable time period.
2100 ABORT System resourc es required to run this test a re no t available.
1. Retry the command at 1-minute intervals a maximum of 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 Tone-Clock circuit pack. A failure of this
test indicates that we are outside of Stratum 4 or Stratum 3 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, refer to "Approach to Troubleshooting" in the Synchronization
(SYNC) Maintenance section of this manual.
PASS The Tone-Clock circuit pack does not detect timing any PPM errors. This
indicates that the external synchronization timing source is valid or that the
system synchronization reference is a Tone-Clock circuit pack. Use the status
synchronization command to verify that the desired synchronization
reference is providing timing for the system.
