Power Failure Connections - Panasonic KX-TDA600 - Hybrid IP PBX Control Unit Max. 1008 Ports Installation Manual

2.13 Power Failure Connections

2.13.1 Power Failure Connections
When the power supply to the Hybrid IP-PBX fails, power failure transfer (PFT) will switch from the current
connection to the Power Failure Connection. Refer to "1.13.9 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
CO line and extension cards can be used for Power Failure Connections:
• Analog CO line card: ELCOT16 (4 PFT ports)
• Extension card: EMSLC16 (4 PFT ports), ESLC16 (4 PFT ports), DHLC8 (2 PFT port) and SLC8
(2 PFT port)
To 1 analog CO line card, connect only 1 extension card.
Notes
• Power Failure Connections must be made within the same shelf.
• By programming the Hybrid IP-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.
