ABSTRACT:
The invention relates, inter alia, to a method in which, by reducing the spectral power density in an underfrequency range (UB) of a transmitting/receiving unit, the fact that the underfrequency range (UB) should not be used to send data is indirectly transmitted. This method is particularly suitable for xDSL processes.
