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,
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
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
