Patent ID: 8614944

Claim:
A transmission system for transmitting communication data from at least one data source to several terminals in a passenger aircraft by way of at least one distributor that is connected to the data source, wherein each terminal by way of an input port and an output port is daisy chained to at least one terminal chain; the first and the last terminal in each terminal chain by means of a shunt connection are directly interconnected so that the communication data between the first terminal and the last terminal in the terminal chain is transmitted from terminal to terminal in the chain when all the terminals are interconnected; and the communication data from the first terminal in the terminal chain up to an inactive terminal and from the last terminal in the terminal chain up to the inactive terminal is transmitted when the connection between the terminals in the terminal chain is interrupted; wherein the distributors of several terminal chains are interconnected by way of a distributor connection so that if the supply to one of the several terminal chains fails, by way of a distributor the respective chain is supplied by way of an adjacent distributor.
