exchange analog lines or PBX extensions).

Connecting the FXS Analog Lifeline

The device supports Analog Lifeline. If the device loses power, for example, due to a power outage
or the unplugging of its power cable, it automatically routes calls from a POTS telephone ("lifeline"
phone), connected to an FXS port, to the PSTN (instead of the IP network).
The FXS Lifeline extension or phone connects to FXS Port #1 while the PSTN/PBX connects to
FXO Port #1. When the Lifeline is triggered, the FXS line automatically connects to the FXO line
and calls between these entities can occur.
Note: The FXS Analog Lifeline feature is a separate orderable item and is only supported on
specific hardware configurations with combined FXS and FXO interfaces. For more information,
contact your AudioCodes sales representative.
