b. The indicated Tone-Clock circuit pack has been made unavailable via the
busyout tone-clock UUC
command. It only applies to systems which
have the High or Critical Reliability Option administered, because only a
standby Tone-Clock circuit pack may be made busy by that command. To
resolve this error, execute the
release tone-clock UUC
command for the
alarmed circuit pack.
c. This error type indicates that the circuit pack has been removed or has
been insane for more than 11-minutes. To clear the error, reinsert or
replace the circuit pack.
d. The Tone-Clock circuit pack in the PPN is not a TN780 while a Stratum 3
synchronization is administered. Replace the Tone-Clock in the PPN with a
TN780, or change synchronization administration to Stratum 4 if a Stratum
3 clock is not being used.
e. The tone-clock has reported an out-of-lock condition. A aux value of 1
indicates this error is an out-of-lock with the primary reference. A aux
value of 2 indicates this error is an out-of-lock with the secondary
reference. It could not lock onto the frequency of that synchronization
reference. This will lead to a change in the synchronization reference if the
condition continues.
f. The Tone-Clock circuit pack may be defective, however it may be a
software failure that can be corrected by testing.
1. Check to see if the board is duplicated (
list cabinet
and
status
port-network
) on the affected port network.
2. If the board is not duplicated, use test tone UUCSS long to resolve
the errors. 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, meaning that
no dial tone or touch tones are available during this interval. This
will probably not affect calls in progress, but could cause a call
origination to abort or a user not to get dial tone when going off
hook.
3. If all tests pass and the alarm does not resolve, retest with
test tone
UUCSS long clear
.
4. If the test passes, terminate the repair process. If the test fails,
replace the circuit pack at the customer’s convenience.
5. If this error was logged against the standby Tone-Clock, and if the
Aux Data value was 18369, SYNC (Synchronization) maintenance
acts on this error. No corrective action is required. For any other
Aux Data, go to the next step.
6. If the board is duplicated, switch to the standby side (set tone).
7. Test the alarmed board (test tone UUCSS long). This resets the
board and is required to reload on-board RAM associated with the
TN2182’s DSPs.
