Notes:
a. Error Type 1

This error indicates the circuit pack totally stopped
functioning or it was physically removed from the system.
NOTE:
The alarm is logged approximately 11 minutes after the circuit pack is
removed/SAKI Sanity test (#53) fails.
If the circuit pack is not present in the system, insert a circuit pack in the
slot indicated by the error to resolve the error.
If the circuit pack is present in the system, it is faulty and must be replaced.
See the preceding section,
‘‘Replacing the IPSI or Tone-Clock Circuit
Pack’’ .
If the faulty circuit pack is in standby mode, a MINOR alarm is raised, but
no other system action is taken. If the circuit pack is the active Tone-Clock,
further effects of this error depend on the system’s reliability option.
If an interchange is attempted in an MCC EPN 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
‘‘Replacing the IPSI or Tone-Clock Circuit Pack’’ .
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.
b. Error Type 18

The indicated IPSI or Tone-Clock circuit pack has been
made unavailable via the busyout tone-clock PC or the busyout
ipserver-interface UC command. 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 PC, or release
ipserver-interface command.
