Power Fail (PF) Transfer Circuits
With the installation of trunk cards to support the PF (Power Fail) transfer option, four
trunks per trunk card may be directed to station sets if power to the Coral IPx Office
system is interrupted. This arrangement, referred to as power failure transfer,
completely bypasses the system, allowing specific stations to originate outgoing calls
and/or continue answering incoming calls.

Stations
The SLT (single line telephone) set can be used as a power failure station. Figure 5-6
