Driver circuit for at least one subscriber terminal, comprising a first driver ( 14 ) for amplifying the power of a direct-voltage signal applied for supplying power to the subscriber terminal, the first driver ( 14 ) being supplied by a first supply voltage (V<SUB>1</SUB>), and comprising a second driver ( 37; 37 a , 37 b), following the first driver, for modulating high-frequency signal currents onto the power-amplified direct-voltage signal. |
