2.1.4.3 Cabling the 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. Therefore, you can use
the Lifeline phone even when MP-11x is not powered or not connected to the network.
The Lifeline feature is implemented as follows, depending on FXO/FXS support:
„ For devices providing only FXS ports: A single Lifeline connected to Port #1 using a
splitter (not supplied) is available.
„ For devices providing FXS and FXO ports: A splitter is not required - all FXS ports
are automatically connected to corresponding FXO ports (i.e., FXS Port #1 to FXO
Port #5, FXS Port #2 to FXO Port #6, and so on).
„ For devices providing only FXO ports: A Lifeline is not available.
Note: The use of the Lifeline upon network failure can be disabled using the
LifeLineType ini file parameter (described in the User's Manual ).
The Lifeline’s splitter connects pins #1 and #4 to another source of an FXS port, and pins
#2 and #3 to the POTS (FXS) phone. Refer to the Lifeline splitter pinouts in the figure
below:
