Abstract
In a process for transmitting items of information between devices of an indirectly controlled exchange system via time division multiplex (TDM) channels, with multiple repetition of the items of information, the items of information comprise a plurality of bytes including a number byte which numbers the relevant item of information. The items of information are transmitted by means of buffer stores and multiplexers. The item of information also include a acknowledgment bytes which acknowledge the correct reception of previously transmitted items of information. The reception of acknowledgement bytes is also evaluated as a signal that the TDM channel previously used to transmit the acknowledged information has been released for the transmission of a further item of information.
