8.1.2 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.
8.1.3 SWITCH module The Switch module realizes a "solid state" switch (MOSFET) device for the distribution of the power necessary for the proper working of all the modules of the ECOS-D RBS. In particular its primary task is to distribute the 13,2 Vdc nominal voltage (Master voltage) and 7 Vdc nominal voltage (Slave voltage). The 7 Vdc Slave voltage is used by all the other modules to power their logic. It is generated by the switch module for direct conversion from the 13,2 Vdc Master voltage.
8.1.4 DC/DC module The DC/DC module is a continue power voltage converter from an external power source to the internal power level of ECOS-D devices. The converter, other than the power voltage conversion, is able to galvanically insulate (1500Vrms) the internal 13,2 Vdc power distribution from the external power source and a 28 Vdc power distribution to the 110W PA module. LED Color Label Description 1 Green Vout OK Normally operating Red NA Green Vin OK Red NA 2 Normally operating 8.1.
The front panel is provided with bi-color leds to help in troubleshooting the system.
8.1.6 Power Amplifier module - PA The “Power Amplifier” (PA) module is a wide band RF amplifier in UHF (450 526 MHz). Their time of TX ramp up/down is less than 1200 µsec. This makes the module compatible with the stringent demands of digital transmission.
