2.10 Power Failure Connections

2.10.1 Power Failure Connections
When the power supply to the Hybrid IP-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 Hybrid IP-PBX will remain fully operational and the
connection will not switch to the Power Failure Connection.
Using Analog CO Line Card and Super Hybrid Ports
In the event of power failure, SLTs connected to Ports 1 and 2 of the Super 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.
