Abstract
A device for joining to a telephone auto-switch of a line connected to a subscriber apparatus, characterized in that a line wire connected to a subscriber device is connected to the input of a first secondary winding of a transducer, the output being connected on the one hand to one of the terminals of a capacitor, on the other hand, to a first resistor connected to the negative terminal of a dc voltage source, the other line wire connected to a subscriber apparatus is connected to the output of a second secondary winding of the transducer whose input is connected, on the one hand, to the other terminal of the capacitor and, on the other hand, to a terminal of the coil of a relay whose other terminal is connected to the positive terminal of the dc voltage source by means of a second resistance; the primary winding of the transducer is connected to the telephone auto-switch.
