Abstract
The present invention concerns a method for the manipulation-proof separation of message streams, which are transmitted in the subscriber loop (3) of a communication network via a medium (30) that is common to several subscribers, where first measures (22, 43) are taken to separate the message streams for transmission via the common medium, which are identical for all message streams, and for connections between at least one subscriber (4) connected to the communication network via the common medium, and another subscriber, supplementary measures (111, 112, . . . , 11n; 42) are taken from end to end, which were agreed between these subscribers for these connections, as well as a suitable system and a suitable subscriber facility.
