ABSTRACT:
A communication system includes a plurality of communication stations communicating with each other over a communication channel, wherein each station is provided with a station number which is transmitted as part of a data signal. Transmission control circuitry in each station detects the presence of a carrier wave on the communication channel indicating that another station is transmitting data. The station number is read from the transmitted data and is used to determine the length of a waiting period during which no carrier wave is detected, and after which the station can transmit data. Data collision circuitry is provided which causes data retransmission in the event of a data collision on said channel, after a waiting period determined by the station number of the transmitting station.
