Line interface for an information transmission network including a filter 1, having two input terminals (e1, e2) connected to information transmission wires and two outputs (s1, and s2), characterised in that the filter consists 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 including a resistor (R4) mounted in parallel with the capacitor (C2) mounted in series. <IMAGE>
