5.7 PA Speech, Spare Speech, WIP Speech, Comms
and Spare Comms Cable Faults
PA Speech Cable Faults, Spare Speech Cable Faults, and WIP Speech Cable Faults refer to the connections
between SPIF cards and Secondary ECPs and equipment racks (remote units). As can be seen in the Figure
below, the PA Speech, Speech Backup, and WIP Speech terminals will correspond to the respective Fault on the
ECP System Fault Display.
NOTE: Any WIPS Module Failure or WIP Speech cable fault will activate ‘WIP SYSTEM FAULT’ LED on
the ECP System Fault Display. The LED will flash while unacknowledged and be steady for a
latched or acknowledged fault.
