Abstract
A digital transmission system includes a plurality of stations sharing a common transmission line. Variable length messages, set off by flags, are exchanged between pairs of stations. While a message is being received, the downstream portion of the transmission line is segmented to permit simultaneous use by another station pair. If a message is received from an upstream station while a message is being transmitted downstream, an abort message flag terminates the transmitted message abruptly to permit flowthrough of the received message. When any station is not in use or out of order, it is bypassed to permit use of the transmission line by the rest of the stations.
