5.6.3 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 Analog Lifeline is available on the single FXO port with three FXS ports hardware
configuration. The analog Lifeline phone (POTS phone) connects to FXS Port #1; the
PSTN/PBX connects to the FXO port. Once the Lifeline is activated, the FXS line
automatically connects to the FXO line.
To cable the FXS Lifeline:
1. Connect the analog Lifeline telephone to FXS Port #1.
2. Connect an analog PSTN line to the FXO port, labeled FXO.

Note: Analog Lifeline cabling is applicable only if the device is ordered with the
combined hardware configuration of FXS and FXO interfaces.
