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. <IMAGE>

Claim
1. A communication system comprising a main station which, in operation defines a frame containing a specified number, which is variable, of time slots; and a plurality of substations each including selection means for selecting a time slot fortransm ission of information to the main station: characterised in that the selection means in a substation comprises means defining an identity number exclusive to that substation, means for determining a remainder after dividing the identity number bythe number of time slots, and means for using the remainder to determine the time slot in which transmission takes place.
2. A communication system according to claim 1 in which the main station includes means for recog nising a time slotwhich is mutilated by virtue of two or more substations having transmitted in it and means for adjusting the number of slots in a subsequent frame whenever such a mutilated time slot is recognised.
3. A communication system substantially as described with reference to the accompanying drawings.', "Printed in the United Kingdom for Her Majesty's Stationery Office, 8818935, 5126 18996.
