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

Error Test
Code Result Description / Recommendation
None, ABORT The system could not allocate the necessary resources for the test.
1001
1. Wait 1-minute, and retry the test.
2000 ABORT Response to the test 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 up to 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
2. If the Tone-Clock circuit pack is a slave clock, then the EI to which it is
3. If no problem can be found with the incoming synchronization signal,
2 FAIL This error indicates that Tone-Clock circuit pack has inaccurately detected loss
of signal on the incoming synchronization timing source.
4, 8 FAIL The local oscillator on the Tone-Clock circuit pack has failed.
16, 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
64 FAIL This message is only sent when an uplink message has reported the loss of
valid synchronization timing information coming into this port network. It has
been reported in TDM-CLK Error Log entries; one or more of 1025, 1281, 1537,
2049 and 2305.
1. Resolve the errors indicated. No separate corrective action is required.
