7.1.2 4 Lines Interface module - LIF
The "4 Lines Interface” (LIF) module is the module that is able to manage up to 4 lines with
4W interface + (E&M). This module is equipped with devices for numerical computation
(DSP, FPGA) and control (microprocessor) combined with the electrical interfaces for the 4
wires lines.
The “Line Interface” (LIF) module is also able to manage redounded links over the 4 wires
interfaces.
4 wires interfaces are used by the device to connect this Radio Base Station to up to other 4
Radio Base Stations to build a Simulcast network.
The front panel is provided with bi-color leds to help in troubleshooting the system. The table
below describes the meaning of the leds:
