2.12.1 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.
Note
While DC power is provided by the backup batteries, the Hybrid IP-PBX will remain fully
operational and the connection will not switch to the Auxiliary Connection.
Using Analogue Trunk Card and Extension Card
Auxiliary 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 Auxiliary Connections:
• Analogue trunk 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 analogue trunk card, connect only 1 extension card.
Note
By programming the Hybrid IP-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 Auxiliary Connection. However, if no special
programming is performed, the connection will be dropped when power returns.
