1.13.7 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 (→ 1.3.5 Call Park).

1.13.8 Power Failure Transfer

Description
If the power supply to the PBX fails, specific single line telephones (SLTs) are automatically connected to
specific CO line (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.
[KX-TDA600]
• 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 Cards: ELCOT16 (4 PFT ports)
Extension Cards: EMSLC16 (4 PFT ports), ESLC 16 (4 PFT ports), DHLC8 (2 PFT ports), SLC 8 (2
PFT ports)
Only connect one extension card to each CO line card.
Note
Power Failure Connections must be made within the same shelf. An extension card cannot have a
Power Failure Connection with a CO line card of another shelf.
