Abstract
In a variable configuration multiplex transmission method, correct sending of data to their respective addressees (terminals 22, 24, 26 and/or 28) supposes that reception station (34) can determine which is the channel configuration from amongst configurations (A, B, C and/or D) that is active. This invention is adapted to proceed to such a channel determination by multiplexing a predetermined particular character from the active channels, directly transmitting over transmission channel (32) the multiplexed predetermined character burst, receiving (34) the multiplexed character burst, and using the received character burst in order to read a pre-registered table which directly gives out that channel configuration which has active channels.
