TONE-BD (Tone-Clock Circuit)
Issue 1 June 2005

If an interchange is attempted in an MCC PN and the system is unable to activate the 
standby Tone-Clock, Emergency Transfer is activated. When this happens, both circuit 
packs are faulty and must be replaced. See 
If a successful interchange occurs in response to a failure of the active Tone-Clock or if a 
standby Tone-Clock fails, the faulty Tone-Clock should be replaced.
c. Error Type 18: the indicated IPSI or Tone-Clock circuit pack has been made unavailable by 
busyout tone-clock location or busyout ipserver-interface location
This error applies only to high- or critical-reliability systems (an active Tone-Clock may not 
be busied out). To resolve this error, execute release tone-clock location, or 
release ipserver-interface location.
d. Error Type 23: the circuit pack has been logically administered but not physically installed. 
Installing the circuit pack will resolve the alarm.
e. Error Type 125: a wrong circuit pack is inserted in the slot where this circuit pack is logically 
administered. To resolve this problem, either:
1. Remove the wrong circuit pack, and insert the logically administered circuit pack.
or
Use the change circuit-pack command to re-administer this slot to match the circuit 
pack inserted.
f. Error Type 126: the port network specified in the PORT field of the error log entry booted 
up without a Tone-Clock circuit pack, or with a one that cannot communicate at all with the 
system. The error is logged five minutes after the port network is restarted. If no circuit pack 
is present, install one of the proper code. If there is a circuit pack present, replace it. See 
g. Error Type 257: this error indicates transient communication problems with this circuit pack. 
This error is not service-affecting and no action is required.
h. Error Type 513: this circuit pack has an on-board hardware failure. Replace the circuit pack 
using the procedure described in 
i. Error Type 769: this error can be ignored, but look for other errors on this circuit pack.
