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 "1.13.9 Power Failure Transfer" in the Feature Manual
for further information.

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.
