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.
