Description/ Recommendation
This error indicates that Tone-Clock circuit pack has inaccurately detected
loss of signal on the incoming synchronization timing source.
The local oscillator on the Tone-Clock circuit pack has failed.
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.
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.
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.
There is an on-board failure of TDM clock hardware.
1. Replace the Tone-Clock circuit pack.
TDM Bus Clock Circuit Status is sane. There are no clock-detection circuit
problems on the Tone-Clock circuit pack.
