Line interface for an information transmission network comprising a filter 1, having two input terminals (e1, e2) attached to information transmission wires and two outputs (s1, and s2), characterised in that the filter is composed of an input stage (11 or 12) associated with each input (e1, e2) and of a bandpass filter (13, 14) between the input stage and the output, this bandpass filter comprising a resistor (R4) mounted in parallel with the series-mounted capacitor (C2). <IMAGE>
