ABSTRACT:
A radio transmission system in which two subscribers use only one of possibly several frequency channels for a mutual connection is characterized in that in the individual frequency channel which is provided for the connection of the two subscribers the information flow of the subscriber transmitting at a particular moment in time is interrupted in, preferably, regular time intervals for a very short time in comparison with the transmission time in order to establish a return connection, in the manner of a time slot channel, having a low transmission capacity in comparison to the actual frequency channel. In this time slot channel, information of the return connection is transmitted.
