2.11 Auxiliary Connection for Power Failure Transfer

2.11.1 Auxiliary Connection for Power Failure Transfer

When the power supply to the Hybrid IP-PBX fails, power failure transfer (PFT) will switch from the current connection to the Auxiliary Connection. Refer to "2.4.1 Power Failure Transfer" in the Feature Guide for further information.
Auxiliary Connection is required to implement this feature.

Connection

Auxiliary 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 Auxiliary Connections:
•Analog CO line cards: LCOT16 (4 PFT ports), and LCOT8 (2 PFT port)
•Extension cards: MSLC16 (4 PFT ports), SLC16 (4 PFT ports), DHLC8 (2 PFT port) and SLC8 (2 PFT port)
To 1 analog CO line card, connect only 1 extension card.

Note

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 Auxiliary Connection. However, if no special programming is performed, the connection will be dropped when power returns.
