ABSTRACT:
In a full-duplex data communication system, the signal-to-noise ratio, error rate and occurrences of out-of-sync condition of signals transmitted on the data channel of a first transmission medium from a first station to a second station are detected by the latter and a first set of quality signals of the first transmission medium is generated. The signal-to-noise ratio, error rate and occurrences of out-of-sync condition of signals transmitted on the data channel of a second transmission medium in the opposite direction are likewise detected by the first station and a second set of quality signals of the second transmission medium are generated. The first set of quality signals are modulated and transmitted on a control channel of the second transmission medium from the second station and received and demodulated by the first station, which derives a speed setting command signal from the second set of quality signals as well as from the first set of quality signals represented by the demodulated signals, and the transmission speed of the first station is controlled according to the speed setting command signal. The speed setting command signal is modulated and transmitted on a control channel of the first transmission medium from the first to second station, which demodulates it and controls its transmission speed according to the demodulated speed setting command signal.
