Abstract (en)
[origin: EP1510988A2] The network has an electrical line connecting the individual components of the hazard warning system for the mutually uninfluenced and independent transmission of at least two information flows and first and second circuit arrangements with suitable filter characteristics for coupling signals into first and second channels in first and second separated frequency bands (FB1,FB2) . An optional information transmission type occurs in the first channel and a digital transmission technique is used in the second channel. An independent claim is also included for the following: (a) a hazard warning system.
