ABSTRACT OF THE DISCLOSURE: The present invention relates to a loop-circuit for a telephone line, more particularly, a termination circuit for a trunk line in a private telephone installation. This circuit includes a transistor having a first electrode directly connected to one of the two wires of the line, a second electrode connected to the other wire of the line via a resistor and a gate electrode connected through a resistor to one of the wires of the line and through a capa- citor to the other wire of the line. A switch cuts off the transistor , and another switch disconnects one of the plates of the capacitor from the rest of the circuit. The invention is applicable in private telephone installa- tions.
