1. A circuit for computer registration of tariff units using dialing impulses from the conversation wire and counter impulses from the counter wire of the subscriber loop circuit, characterized in that it comprises the first separating element (Tr1), preferably a transoptor, connected by means of a galvanic connection with the counter wire (C) of the subscriber loop circuit (AZL), and the second separating element (Tr2), preferably a transoptor, connected by means of a galvanic connection to the conversation wire (a) of the subscriber loop circuit, whereas the outputs of the separating elements (Tr1, Tr2) are connected by means of a galvanic connection with each other and with one of the telephone exchange wires (m), which is connected with the microcomputer registration device (MUR).<IMAGE>
