Proposed is a method of bidirectional data transmission over a twowire line. Digital data destined for transmission or reception, e.g. using discrete multitone modulation (DMT), are modulated or demodulated as appropriate and separated by timedivision multiplexing. The appropriate multiplex time frame is subdivided into a predetermined number N of time slots and a number K of those time slots is assigned exclusively to one direction, e.g. transmission, the remaining time slots (=NK in number) being assigned exclusively to the other direction (e.g. reception). |
