METHOD FOR TRANSMITTING CHARGES DETERMINING SIGNALS OVER A DATA TRANSMISSION PATH AND DEVICE FOR VOLTAGE LEVEL GENERATION

摘要

The invention relates to a method for the transmission of charges determining signals over a data transmission path, wherein a line voltage level (101) is predetermined, wherein the output voltage (100) supplied by a driver device (201) is determined by a voltage detecting device (103). A transmission function of the data transmission path is determined for at least one frequency by means of which the charges determining signals are transmitted from a central office to a subscriber's station. A set value (117) is inputted into a set value comparing unit (118) in order to provide a control signal (119). The output voltage (100) is modified in such a way that the inputted set value (117) in impinged upon with the transmission function of the data transmission path depending on the control signal (119) and a driver output voltage level (108) is outputted by the driver device (209), whereby the line voltage level (101) is predetermined.
