3.13 Power Failure Connections

3.13.1 Power Failure Connections
When the power supply to the PBX fails, power failure transfer (PFT) will switch from the current connection
to the Power Failure Connection. Refer to "2.4.1 Power Failure Transfer" in the Feature Manual for further
information.
Connection
Power Failure Connection connects a specific SLT and a CO line in the event of power failure. The following
analog CO line and extension cards can be used for Power Failure Connections:
Analog CO line cards: LCOT16 (4 PFT ports) and LCOT8 (2 PFT ports)
Extension cards: MSLC16 (4 PFT ports), SLC16 (4 PFT ports), DHLC8 (2 PFT ports) and SLC8
(2 PFT ports)
To 1 analog CO line card, connect only 1 extension card.
Note
By programming the PBX, a CO line conversation established during power failure can 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.
