13.1.11 Power Failure Transfer
Description
If the power supply to the PBX fails, specific single line telephones (SLTs) are automatically connected to
specific CO lines (
Power Failure Connections ). The PBX will switch from the current connections to the Power
Failure Connections, and all existing conversations will be disconnected.
Only CO line conversations handled by Power Failure Connections can be made during a power failure.
Conditions
[General]
•
Only CO line calls can be made during a power failure. All other features do not work.
•
Through system programming, it is possible to allow CO line 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.
