Abstract
The circuit arrangement comprises a charge information memory (5) installed in the exchange with an electronic meter which stores the charge pulses which are generated during a call by the conventional charge pulse generator in the exchange but which are not transmitted via the telephone line to the subscriber, and a charge signal transmitter (7) which is connected to the output of the memory (5) and which comes into operation only at the end of the call in order to transmit the stored charge information in the form of multi-frequency code signals to the subscriber within a time period which is shorter than a ringing pulse cycle. The charge signal transmitter (7) is connected to the telephone line (a, b) via a changeover switch (8) which is activated at the end of the call and which simultaneously disconnects the transmitter output from the other exchange circuitry. Since no charge pulse transmission is required during the call, the charge pulse frequencies can be selected purely with a view to optimum charge pulse transmission without considering the voice band; furthermore, the circuits can be simplified with no need for frequency filters.
