Power Failure Transfer
Description
When the power supply to the PBX fails, specific SLTs and/or ISDN terminal devices 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
[General]
•
Only trunk calls can be made during a power failure. All other features do not work.
•
DC Power Source
If the DC power is available from backup batteries, even if the AC power fails, the PBX will remain fully
operational.
[KX-TDA100/KX-TDA200]
•
The analogue trunk cards and extension cards and the number of ports which can be used for Power
Failure Connections are as follows:
Trunk Cards: LCOT16 (4 ports), LCOT8 (2 ports), and LCOT4 (2 ports)
Extension Cards: MSLC16 (4 ports), SLC16 (4 ports), DHLC8 (2 ports) and SLC8 (2 ports).
Only connect one extension card to each trunk card.
Note
Power Failure Connections between analogue trunk cards and extension cards should be done as
per system programming so that conversation is maintained when the power is restored and the
MPR is recovering.
•
The BRI8 (one port) and BRI4 (one port) cards can also be used for Power Failure Connections. For
details about Power Failure Connections, refer to the Installation Manual.

•
Ports 1 and 2 of the LCOT card installed in the least slot number and ports 1 and 2 of the Super Hybrid
ports can be used for Power Failure Connections.
Note
The Power Failure Connections between the LCOT card and Super Hybrid ports are automatically
kept so that the conversation is maintained when the power is restored and the Main Board is
recovering.
•
The BRI2 (one port) card can also be used for Power Failure Connections. For details about Power
Failure Connections, refer to the Installation Manual.
