maintenance circuit pack and the state of Emergency Transfer in
the cabinet display:
■ on: If this is a Simplex PPN or an EPN, then designated analog
phones in this cabinet are cut through to CO trunk lines only in
an emergency situation. In a High or Critical Reliability System,
the Emergency Transfer Switches on both SPEs in the PPN must
be in the on position before Emergency Transfer is invoked for
the PPN.
■ off: Regardless of Simplex or Duplex, PPN, or EPN,
Emergency Transfer is off and cannot be invoked. The switch
should only be in this state when a service technician is on
sight.
■ auto-on: The switch is in the or auto position, however,
because of a serious system fault, system software has invoked
Emergency Transfer.
■ auto-off: Switch in the auto position; because system has no
serious faults, system software has not invoked Emergency
Transfer
■ unavail: EPN is down
