5.6.2 Power Failure Transfer

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.
•
The following SLT ports and LCOT ports are connected during a power failure. 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.
