Transmission of signals between two local networks, dividing high rate signal to two lower rate signals and multiplexing

摘要

Signals are transmitted between a first local network (1) and a second local network (2), both operating at a high rate, e.g. 10 Mb/s, over digital channels (7) of lower rate. A first step involves dividing a signal output by the first high rate network (1) into two signals to be fed along the channels (7) having a rate corresponding to digital lines of lower rate. Then a step of multiplexing (8) of the channels (7) is performed by calculating positive justification to one of the channels and by applying the same justification to the other channel. Thus obtained multiplexed signal is transmitted (9) towards a receiver (10). At the receiver a high rate signal is generated corresponding to the received multiplexed signal and supplied to the second local network (2).
