2.13.1 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 Guide for further information.

Note

While DC power is provided by the backup batteries, the PBX will remain fully operational and the connection will not switch to the Power Failure Connection.

Using Analogue Trunk Card and Extension Card

Power Failure Connection connects a specific SLT and a trunk in the event of power failure. The following analogue trunk and extension cards can be used for Power Failure Connections:

Analogue trunk cards: LCOT16 (4 PFT ports), LCOT8 (2 PFT ports), and LCOT4 (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)

To 1 analogue trunk card, connect only 1 extension card.

Note

By programming the PBX, a trunk 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.
