Description / Recommendation
66 FAIL There is an on-board failure of TDM clock hardware.
1. Enter test tone location 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 with
test tone-clock location long clear.
3. If the test passes, the repair process is completed. If the test 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.
