In a method and device for the transmission of a multiplicity of signals having different frequencies between a base station and a module situated at a location remote from the base station via a single, common cable connection, some of the signals being transmitted from the electronic assembly to the module and, in general simultaneously, the remaining signals are transmitted in the opposite direction. Each of the base station and the module has bandpass filter bank therein having a multiplicity of bandpass filters, the number thereof being a function of the number of channels to be transmitted, with which the respectively received signals are spectrally separated from one another so that they are available for further signal processing in the base station, or for further use in the module.
