TDM Bus Clock PPM Inquiry Test (#150)
This test evaluates the quality of the synchronization source for the Tone-Clock
circuit pack
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.
66 FAIL There is an on-board failure of TDM clock hardware.
1. Use test tone UUCSS long to resolve the problem. The long test resets
the board and is required to reload on-board RAM associated with the
TN2182”s DSPs. The effect is that tone detectors are taken out of
service momentarily and tones are removed from the TDM bus for
about 10 seconds. This means that no dial tone or touch tones are
available during this interval. It probably will not affect calls in progress,
but could cause a call origination to abort or a user will not get dial tone
when going off hook.
2. If the test passes and the alarm does not resolve, retest (test tone
UUCSS long clear).
3. If the test passes, terminate the repair process. If it fails, replace the
circuit pack at the customer’s convenience.
66 FAIL There is an on-board failure of TDM clock hardware.
1. Replace the 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.
