the circuit pack and put it back into service. If the command is not
successful, replace the circuit pack using the procedure described in the
preceding section,
alarmed circuit pack is the active Tone-Clock of a duplicated pair, first
interchange Tone-Clocks via the set tone-clock PC command to avoid a
service outage. If the error occurs again within 15 minutes, follow normal
escalation procedures.

clock signals from the reported Tone-Clock circuit pack, which was active
at the time of the error. The effect of any of these errors is described in the
table for error type 1. Diagnosis of the problem is the same for all four error
types, with the exception noted below.
1. Examine the Hardware Error Log for errors reported against circuit

Tone-Clock circuit pack should be replaced. See the preceding
section, ''How to Replace a Tone-Clock Circuit
NOTE:
Replacing the circuit pack and retesting it with the test
tone-clock command is not adequate to retire this alarm and
return the Tone-Clock Circuit Pack to full service; the Clock
Health Inquiry test (#46) will continue to fail. Because the
ability to generate clocks was considered lost, once any
repairs have been made it is necessary to execute the set
tone-clock PC override command, forcing the circuit pack to
become active. If the problem has not actually been corrected,
this action may cause a disruption in service for active digital

board were lost. If the reported Tone-Clock circuit pack is in a Port
Network with duplicated Tone-Clocks, the problem may lie with the
circuit pack responsible for selecting the active Tone-Clock circuit
pack (the t/c selector).
For a PPN, the t/c selector is the DUPINT circuit pack on
carrier A.
For an EPN, the t/c selector is the active EXP-INTF circuit
pack that is connected to the PPN. This is EXP-INTF 2A01 or
2B02 for EPN1 and 3A01 or 3B02 for EPN2.
