An apparatus and method are disclosed for transmitting a single high speed bit stream over several low-speed channels. The high-rate bit stream is separated into several low rate bit streams which are modulated and transmitted over individual data channels. At the receiving end the relative time legs of the channels are determined and the signals from the data channels are delayed to insure that they are demodulated simultaneously. The demodulated signals are then combined into a single high-rate output bit stream. All signal processing takes place in a single modem at each end adapted to handle the several channels simultaneously and to determine the differential delay therebetween.
