TDM-CLK (TDM Bus Clock)
b. The indicated Tone-Clock circuit has been made unavailable via the
busyout tone-clock UUC command. It only applies to systems with the
high- or critical-reliability option administered, because only a standby
Tone-Clock circuit 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 EPN 1 is not a TN780 although Stratum-3
synchronization is administered. Replace this Tone-Clock 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 IPSI's Tone-Clock circuit or Tone-Clock circuit pack may be defective,
however it may be a software failure that can be corrected by testing.

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.
