A method and a system for transmitting confidential and non-confidential data blocks between intake units ( 1, 1' ) and output units ( 3, 3' ) of a communication system. The communication system has intake units ( 1 ) for confidential data blocks, intake units ( 1' ) for non-confidential data blocks, output units ( 3 ) for confidential data blocks, and output units ( 3' ) for non-confidential data blocks. A data distribution unit ( 2 ) transmits data blocks with confidential information from the intake units ( 1 ) for confidential information to the output units ( 3 ) for confidential information and data blocks with non-confidential information from the intake units ( 1' ) for non-confidential information to the output units ( 3' ) for non-confidential information. The two types of data blocks are differently marked, and the differently marked data blocks are transmitted in this form via the data distribution unit ( 2 ) in dependence on the marking from the intake unit in question to the corresponding associated output unit ( 3, 3' ).
