TDM Bus Clock Circuit Status Inquiry Test (#148)
The TDM Bus Clock circuitry is checked for sanity. Any problems that are found
are reported via error codes

ABORT The system could not allocate the necessary resources for the test.
1. Wait 1 minute, and retry the test.
2000 ABORT Response to the test request was not received within the allowable time
period.
2100 ABORT System resources required to run this test are not available.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1 FAIL This error means the Tone-Clock circuit pack framing verification firmware
reports an error in the clock synchronization signal coming into this Port
Network.
1. If the Tone-Clock circuit pack reporting the problem is a master clock,
then the system synchronization reference is providing a bad timing
source. Refer to SYNC (Synchronization) or STRAT-3 (Stratum 3 Clock)
Maintenance documentation to change the system synchronization
reference.
2. If the Tone-Clock circuit pack is a slave clock, then the EI to which it is
listening is providing a bad timing source. Follow the diagnostic
procedures specified for TDM-CLK Error Code 2305.
3. If no problem can be found with the incoming synchronization signal,
replace the Tone-Clock circuit pack. See
How to Replace the
Tone-Clock Circuit Pack
in the TONE-BD section.
2 FAIL This error indicates that Tone-Clock circuit pack has inaccurately detected
loss of signal on the incoming synchronization timing source.
4
or
8
FAIL The local oscillator on the Tone-Clock circuit pack has failed.
16
or
32
FAIL The circuitry on the Tone-Clock circuit pack used to detect synchronization
timing errors has failed.
1. Errors 2, 4, 8, 16, and 32 indicate that there is poor synchronization
between port networks and external facilities. It may be noticeable to
the customer in the form of errors in data communications. The
Tone-Clock circuit pack is defective. See
How to Replace the
Tone-Clock Circuit Pack
in the TONE-BD section.
