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
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.
PASS TDM Bus Clock Circuit Status is sane. There are no
clock-detection circuit problems on the Tone-Clock circuit
pack.
