These radio links are composed by two units; an indoor unit shf (IDUSHF) (Optionally outdoor unit odu n aerial head)supplied in a single 1U rack containing the rf transmitter (or rf reciver) and a second indoor unit lf (IDU-LF) Supplied in a single 1U rack containing mo/demodulator (QPSK or 16QAM mo/dem) and co/decoder (Mpeg2co/dec+mux). On the front panel, a color display provides the information about the function of each board; the video signals in input and output to codec mpeg2 can be easily checked out. The power supply stage can receive either alternate or direct voltage (even simultaneously); Furthermore, it can be completely removed from its location to allow easy and quick maintenance. The program of the function can be realized either locally by the keyboard, or remotely by means of an interface Ethernet 10/100 Base T which allows a remote connection also through the web. Two other serial interfaces RS 232 and six relè contacts complete the interfaces
