Abstract

Circuit for eliminating transient signals for use in telecommunications with CPU control means, in particular for use in a communications line which connects a subscriber's telephone with the telephone exchange. It comprises means for receiving various input signals and supplying a multitone output signal associated with each of the said input signals, the said receiving means eliminating an undesirable transient present in a predetermined signal of the said input signals, in such a way that none of the output signals includes the undesirable transients and a CPU-actuated control means sensitive to a defined signal of the said input signals received by the said receiving means, in order to generate the said multitone output signals associated with each one of the said input signals. In this way, the subscriber line can be used simultaneously with telephone communication and with a second information signal, each signal being capable of occupying the same bandwidth and the signals can work independently of each other.
