Abstract
A communication system comprises a main station 1 which defines a time frame containing a variable number of time slots. Each of a plurality of substations 2, 3, 4 etc., includes selection means for selecting a time slot for transmission of information to the main station. Each substation has an identity number and it divides this identity number by the number of time slots currently set by the main station. The remainder left after this division process is used to select the time slot in which the substation will transmit its information to the main station. If two substations transmit in the same time slot the mutilated time slot is recognised by the main station at 15 and 16 and the number of time slots defined at 17 for the next frame is changed so as to prevent repetition of such mutilation.
