4.11 Power Failure Ports
4.11 Power Failure Ports
When the power supply to the PBX fails, power failure transfer (PFT) will switch from the current connection
to the Power Failure Connection. Refer to "5.5.2 Power Failure Transfer" in the Feature Guide for further
information.
Using SLC2/LCOT2 Card
In the event of a power failure, a specific SLT is automatically supplied power through the PFT port. The PFT
ports are the SLC1 port and LCOT1 port on the SLC2/LCOT2 card.
Note
A trunk conversation established during power failure can be maintained even when the power returns and
the connection is switched back to the normal configuration from the Power Failure Connection.
