2.12 Power Failure Connections

2.12.1 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
While DC power is provided by the backup batteries, the PBX will remain fully operational and the
connection will not switch to the Power Failure Connection.
Using Analogue Trunk 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 LCOT2/LCOT4 card (installed in the least slot
number).
Note
Even when the power returns, the conversation established during power failure will be maintained.
Using BRI2 Card
LINE 1 and LINE 2 of the BRI2 card can be used for Power Failure Connections.
Note
When the power returns, the connection will switch back to normal configuration from the Power Failure
Connection, and a trunk conversation established during power failure will be dropped.
