Transceiver for transmission over serial bi-directional links having a bi-directional amplifier including an impedance (R) for adaptation to the line and connected to it, a generator (G1) commanded for transmission and supplying the adaptation impedance (R) and the line in parallel, detection device (G2, r) for furnishing a measurement signal (V) representative of either the current circulating in the adaptation impedance (R) when the generator (G1) is active, or the sum of the current in the adaptation impedance (R) and a compensation value when the first generator (G1) is not active. The compensation value is determined so as to make the measurement signal (V) independent of the transmission state of the transceiver.
