2.4.3 Connecting to FXS/FXO Interfaces
The procedure below describes the cabling of the device's FXS and FXO module analog
interfaces.
Warnings:
• To protect against electrical shock and fire, use a 26 AWG min wire to
connect FXO ports to the PSTN.
• Ensure that FXS and FXO ports are connected to the appropriate,
external devices; otherwise, damage to the device can occur.
¾ To connect the FXS /FXO interfaces:
 Using the device's RJ-11 connectors on the FXS/FXO module, connect the device to
the required telephone interfaces:
• FXS: connect the FXS module's ports to fax machines, modems, and/or
telephones.
• FXO: connect the FXO module's ports to telephone exchange analog lines or
PBX extensions.
The RJ-11 connector pinouts are shown in the figure below:

2.4.4 Connecting the Analog Lifeline Phone
The device's FXS modules provide a Lifeline phone connection on Port I. The Lifeline
provides a wired analog POTS phone connection to any PSTN or PBX, which provides
PSTN connectivity upon a power outage or when the network connection fails. For each
FXS module installed in the device, you can configure one Lifeline phone connection (using
Port I).
Notes:
• Analog Lifeline is supported only by the FXS modules.
• The Lifeline feature activated upon network failure can be disabled using
the LifeLineType ini file parameter (described in the device's User's
Manual).
