Abstract

The method is carried out by means of redundant function chains (2, 2'; 6, 6'; 7, 7'). The acknowledgement which is to be expected is also generated during the signal processing (2, 2') and is compared with the actually received acknowledgement in an acknowledgement comparison device (7, 7'). The method allows high signalling reliability to be achieved at relatively low cost without the use of totally functionally reliable components. <IMAGE>
