A data coding device for coding data, to be transmitted as part of data communication, to signals of a first frequency range, not used for voice communication with a first set of performance features, and a conversion device are provided. The conversion device has an interface for connecting a voice terminal having a second set of performace features and for transmission of data coded to signals of a second frequency range that are to be transmitted with the second set of performance features as part of voice communication. The conversion device also has a coding means for recording signals of the second frequency range to signals of a third frequency range that is located outside the first frequency range. Furthermore, a frequency-separating filter for feeding signals of the first and third frequency range into the subscriber line is provided.
