2.13 Power Failure Connections 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.
