发明名称 Circuit for adapting facsimile machine to be connected to a data transmission line and including a differential amp with two high impedance line inputs
摘要 A facsimile machine adapted to be connected to a data transmission line (19) which it shares with a terminal (18), comprising connecting means (1, 20, 40) adapted to be connected, at the input, to the line (19) and to transmit, to a data processing interface (80) of the facsimile machine, differential signaling signals of the line (19) in order, as a function of these signals, directly to connect the interface (80) to the line (19), in which the connecting means (1, 20, 40) comprise a differential amplifier (20) connected to the line (19) by two high-impedance inputs.
