TONE-BD (Tone-Clock Circuit Pack)
6. Attempt again to interchange Tone-Clocks with the set tone-clock
n. Error Type 3840
indicates that the circuit pack has received a bad control message from the
switch.
o. Error Type 3848
a loss of clock. If error 2305 is also logged, see note (j).
p. Error Type 3872
a loss of Data Clocks. This error will impact mainly users on station
connected to Digital circuit packs. These users could be with out service. If
error 2049 is also logged see note (i).
q. Error type 3999
control channel messages to the switch within a short period of time. If
Error Type 1538 is also present, then the circuit pack was taken
out-of-service due to hyperactivity. If Error Type 1538 is not present, then
the circuit pack has not been taken out-of-service, but it has generated
50% of the messages necessary to be considered hyperactive. This may
be completely normal during heavy traffic periods. However, if this error
type is logged when the circuit pack is being lightly used, it may indicate a
problem with the circuit pack or the equipment attached to it.

PC command.
— If the Tone-Clock interchange failed for both t/c selectors:
Replace the standby Tone-Clock circuit pack which could not
be interchanged into and return to this step. (See
Replace a Tone-Clock Circuit
pack as follows:
a. Execute the set tone-clock PC command.
b. Execute a set expansion-interface, if this is an EPN
Tone-Clock.
c. Execute the set tone-clock PC command again.
If these commands successfully complete, the problem has
been resolved.
— If these commands successfully complete, the problem has
been resolved.
— If the Tone-Clock circuit packs successfully interchange when
one EXP-INTF is active, but not when the other one is:
The t/c-selector circuit pack on the failing side is suspect.
a. Replace the A carrier DUPINT or EXP-INTF board that is
active when the Tone-Clock interchange fails.
b. Make sure the new t/c selector is active and execute the set
tone-clock PC command.
— If both Tone-Clocks can be interchanged, and interchanges
succeed when either t/c selector is active, the problem has
been resolved. If the problem persists after following the
above steps, follow normal escalation procedures.
This error is not service-affecting and can be ignored. It
