2.10 Power Failure Connections

2.10.1 Power Failure Connections
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 "2.4.1 Power Failure Transfer" in the Feature Guide for further
information.
Note
If DC power is provided by backup batteries, the PBX will remain fully operational and the connection
will not switch to the Power Failure Connection.
Using CO Line Card and Hybrid Ports
In the event of power failure, SLTs connected to Ports 1 and 2 of the Hybrid Ports (on the Main Board) are
automatically connected to PFT ports 1 and 2 of the first LCOT4 card (installed in the least slot number).
Note
Even when the power returns, the conversation established during power failure will be maintained.
