Connecting the Analog Lifeline Phone
The device supports an analog (FXS) Lifeline phone feature, whereby upon a power outage
or IP network connectivity loss, IP calls are re-routed to the PSTN.
The analog Lifeline is provided by Port
I
on an FXS module. This port connects to the
POTS phone and the PSTN or PBX, using a splitter cable. The splitter cable connects pins
1 and 4 to another source of an FXS port, and pins 2 and 3 to the POTS phone, as shown
in the figure below:
