ABSTRACT:
A duplex transmission control system having active and inactive systems for totally controlling a looped transmission line on which computers and terminal devices are connected through respective stations. Each transmission control unit is operable to transmit and receive specific data related to the priority level specified for each unit. Each transmission control unit suspends the transmission of the clock for a certain period in response to the detection of the clock suspension, then transmits the specific priority data. When a transmission control unit detects its own transmitted signal, it is designated as the active system when another transmission control unit receives the signal defining the active system, it is designated as the inactive system.
