SELECT SWITCH
Emergency Transfer Switch position on the Processor(s) or
the EPN 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
■
<blank> If the system is Simplex, then the 1B Emergency
Transfer indication for the PPN displays a blank. If the
system does not have an EPN, then both the 1A and 1B
Emergency Transfer indications for the EPN displays a
blank.
