TDM Bus Clock Slip Inquiry Test (#149)
This test evaluates the quality of the synchronization source for the Tone-Clock
circuit pack.
NOTE:
This test does not apply to the TN2182
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.
65 FAIL The tone-clock is currently not able to lock on to the current synchronization
reference. If this tone-clock is in the master port networK:
1. Examine the error log for any DS1-BD, SYNC or other TDM-CLK errors
and resolve as applicable.
2. Run this test again via the test tone-clock UUC command.
3. Examine the DS1 measurements to determine if the facility is healthy.
4. Adminsiter a new synchronization reference.
5. Replace the DS1 board currently supplying the reference.
If this tone-clock is in the slave port networK:
1. Examine the error log for any SYNC, EXP-INTF or other TDM-CLK
errors.
2. Run this test again via the test tone-clock UUC command.
66 FAIL There is an on-board failure of TDM clock hardware.
1. Replace this faulty tone-clock circuit pack.
PASS TDM Bus Clock Circuit Status is sane. There are no clock-detection circuit
problems on the Tone-Clock circuit pack.
