Fig. 1 shows a number of stations G1 to Gm connected in series by a coaxial line K. The local area network (LAN) may be expanded by connecting further stations to one or both ends of line K which is not terminated by its characteristic impedance. Messages are transmitted from left to right and from right to left, with buffering being effected in the stations. In a particular section between two adjacent stations, two messages can be simultaneously transmitted, i.e., one message from left to right and the other from right to left. One of the stations Gi, comprising an interface controller INC-L for transmission from right to left and an interface controller INC-R for transmission from left to right, is shown in greater detail by way of an example. Gi is connected to line K by a sender S and a receiver R.
