Abstract: Disclosed is a method for transmitting a low-frequency signal over a data transmission link using a digital high bit-rate signal including the steps of creating a modulated digital high bit-rate signal the average power of which varies according to the low-frequency signal, supplying the modulated digital high bit-rate signal to a first end of the data transmission link, receiving the modulated digital high bit-rate signal at a second end of the data transmission link or at an intermediate node of the data transmission link, and detecting the low-frequency signal by low-pass filtering the received modulated digital high bit-rate signal. According to the invention, the variation of the average power of the modulated digital high bit-rate signal is effected by a variation of the density of “high” bits according to the low-frequency signal.

According to the invention, on the reception side, bit errors in the digital reception signal including their position in the digital reception signal are detected, and from the detected position of the bit errors and from the assignment of the individual bytes of the digital reception signal to the respective sub-signals and transmission lines, which assignment is also known on the reception side, it is determined to which sub-signal the detected bit errors were assigned. From this one or more parameters are determined, which characterize the transmission quality of the transmission lines assigned to each sub-signal and/or allow inferences to be drawn regarding which error mechanisms of the transmission line in question impact its transmission quality. In addition, the invention relates to a reception device for a system for the transmission of a digital signal in inverse multiplexing, which carries out this method.
