13.1.10 Power Failure Restart

Description
When the electricity is turned back on, the PBX restarts, loads its stored data automatically, and logs the event
as a System Restart in the error log.
Conditions
•
In the event of a power failure, PBX memory is protected by a factory-installed lithium battery. There is no
memory loss except the memories of Automatic Callback Busy (Camp-on) (® 1.1.4 Automatic Callback
Busy (Camp-on)) and Call Park (® 3.1.7 Call Park).

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
•
Only CO line calls can be made during a power failure. All other features do not work.
•
The analog CO line cards, extension cards, and the number of PFT ports (ports which can be used for
Power Failure Connections) are as follows:
CO Line Card: LCOT4 (1 PFT ports)
Extension Card: DHLC4 (1 PFT ports)
Note
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.
