Extension Cards: ECSLC24 (4 PFT ports), EMSLC16 (4 PFT ports), CSLC16 (4 PFT ports), ESLC16 (4
PFT ports), DHLC8 (2 PFT ports), SLC8 (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.
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.

•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: LCOT16 (4 PFT ports), LCOT8 (2 PFT ports)
Extension Cards: MSLC16 (4 PFT ports), CSLC16 (4 PFT ports), SLC16 (4 PFT ports), DHLC8 (2 PFT
ports) and SLC8 (2 PFT ports)
Connect only one extension card to one CO line card.
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.
[KX-TDA50]
•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.
