ABSTRACT:
Method and arrangement for transmitting data between a central data station and a plurality of data terminal equipment in a local area network. In order to achieve fast data transmission for simultaneous data lines in a local area network between a central data station and a plurality of data terminals upon interposition of a network node, whereby the known HDLC (high level data link control) data transmission procedure is combined with a data transmission method for data transmission wherein every status change of the binary coded data has a transmission pulse alternating in operational sign allocated to it, a concentrator is utilized as the network node. This concentrator regenerates the incoming HDLC data packet and then transparently forwards them to their desination.
