Claim 11:
12. A method for operating a data network having at least three line branches connected to one another via a common star node in order to distribute message signals from one of the line branches onto other line branches, wherein connected to at least one of the line branches is at least one bus-user device in each case, which is configured to generate in a corresponding transmit mode by means of a corresponding transmit unit at least one of the message signals, characterized in that in the corresponding bus-user device, the transmit unit thereof has a current source circuit which, in generating the corresponding message signal, injects an electric current into electrical lines of the line branch to which the bus-user device is connected, wherein via the current source circuit the lines are connected to an internal impedance value of the current source circuit that in transmit mode is constantly greater than 10 times the value of characteristic impedance of the line branch.
