Power Failure Transfer - Panasonic KX-NS1000 Manual

5.6.2 Power Failure Transfer

Description
When the power supply to the PBX fails, specific SLTs are automatically connected to specific trunks (Power
Failure Connections). The PBX will switch from normal operation to the Power Failure Connections, and all
existing conversations will be disconnected.
Only the trunks handled by Power Failure Connections can be used during a power failure.
Conditions
•
Only trunk calls can be made during a power failure. All other features do not work.
•
Through system programming, it is possible to allow trunk calls that are established during a power failure
to be maintained even when the power returns and the connection is switched back to the normal
configuration from the Power Failure Connection. However, if no special programming is performed, the
connection will be dropped when power returns.
•
The ports on the LCOT2+SLC2 card that can be used as PFT ports (ports that can be used for Power
Failure Connections) are as follows:
Trunk Port: LCOT1 port
Extension Port: SLC1 port
•
To use Power Failure Transfer on a legacy gateway, refer to the documentation of the appropriate PBX.
