3.1.4.4 Cabling the MP-11x/FXS Lifeline
The Lifeline provides a wired analog POTS phone connection to any PSTN or PBX FXS
port when there is no power, or when the network connection fails. Users can therefore use
the Lifeline phone even when the MP-11x is not powered on or not connected to the
network.
On gateways providing only FXS, a single Lifeline, connected to port #1 via a splitter (not
supplied) is available. On combined FXS/FXO gateways, a splitter isn’t required; all FXS
ports are automatically connected to FXO ports (FXS port 0 to FXO port 4 and so forth). On
FXO gateways, a Lifeline isn’t available.
The Lifeline’s splitter connects pins #1 and #4 to another source of an FXS port, and pins
#2 and #3 to the POTS phone. Refer to the Lifeline splitter pinouts in the figure below.
