5.4.2 Connecting to FXO Interfaces
The procedure below describes how to connect the FXO port interfaces to telephone
exchange analog lines or PBX extensions.
Warnings:
•
The device does not include primary telecom protection! Additional protection (usually
a 350V 3-pin Gas Arrestor as described in ITU-T K.44) must be provided at the entry
point of the telecom wires into the building (usually on the main distribution frame or
MDF), in conjunction with proper grounding. If primary protection is not implemented,
permanent damage to the device may occur due to external power surges and/or
lightning over the telecom lines.
•
To protect against electrical shock and fire, use a 26 AWG min wire to connect FXO
ports to the PSTN.
•
Ensure that FXO ports are connected to the appropriate external devices; otherwise,
damage to the device may occur.
•
FXO ports are considered as TNV-3.
Note: This section is applicable only if your device is installed with an FXO module.
An RJ-11 cable connector with the following pinouts is used:


To connect to FXO interfaces:

Using an RJ-11 connector, connect the FXO port/s to the required telephone interface.
5.4.3 Connecting the FXS Lifeline Phone
The device supports an analog Lifeline phone feature, whereby upon a power outage or IP
network connectivity loss, IP calls are re-routed to the PSTN. Therefore, this feature
guarantees call continuity.
Notes:
•
Analog Lifeline is supported only on FXS modules.
•
An analog Lifeline can be setup for each FXS module installed in the chassis.
•
The scenarios (i.e., power outage and/or IP network loss) upon which Lifeline is
triggered is configured by the LifeLineType parameter. For more information, see the
User's Manual .
