How to install the PFCT (Power Fail Cut Through)
With the installation of Power Fail Cut Through (PFCT) circuits, trunk lines may be directed
to station sets (SLT) in the event power is interrupted to the Coral system. 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. One PFCT
card can support a maximum of 8 trunk lines.
Physical Connection
An analog extension can be made as the Power fail Cut Through port. The layout of the
PFCT circuit is given below:
