Abstract

The safety device for electrically insulating a telephone from the line comprises: first means 3 of connection to the telephone line L; second means S of connection to the telephone A; a transfer unit 7 for transferring electrical energy from the telephone line to the device 1 and to the telephone A, the said transfer unit having electrical insulation between the input and the output; and a receiver and transmitter unit 9 capable of receiving and transmitting the signals between the line and the telephone and vice versa, the input and output of the said receiver and transmitter unit being electrically insulated from each other.
