Abstract

For an integrated-services digital broad-band communication system, a multiplexer (100, 110, 120) and an associated demultiplexer (200, 210) are specified, the basic configuration of which (Figure 1a, 2a, 5) allows high flexibility with respect to the number of narrow-band and broad-band signals to be transmitted. The principle of the multiplexer and of the associated demultiplexer consists in that, by connecting the broad-band signal or broad-band signals in parallel and by suitably connecting the narrow-band signals to form one or several narrow-band multiplex signals, a group of digital signals is obtained which have the same bit repetition rate with respect to one another, which is combined to form the time-division multiplex signal to be transmitted in a third multiplexer section (M3, M30, M31). This basic multiplexer and demultiplexer configuration allows the facilities for line coding and line code decoding to be integrated and produced in large-scale integration technology. <IMAGE>
