2.4 Fault Recovery/Diagnostics
2.4.1 Power Failure Transfer (KX-TDA30/KX-TDA100/KX-
TDA200 only)
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 (four ports), LCOT8 (two ports), and LCOT4 (two ports)
Extension Cards: MSLC16 (four ports), SLC16 (four ports), DHLC8 (two ports) and SLC8
(two ports).
To each trunk card, connect only one extension 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.
[KX-TDA30]
• 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.
