ABSTRACT:
A communication system is described comprising different buses which are interconnected via one or more gate connecting elements. There is a transmitter station transmitting a frame that comprises a target address field and one or more destination address fields. If the send and receiver stations are connected to the same bus, the contents of the target address field are sufficient to define the receiver station. In other cases the target address field defines a gate connecting element, whereas the latter fills the the target address field with the contents of one of the other fields. In this way receiver station addresses, which have already been defined on a previous bus, can again be used on the next bus. Furthermore, in a short-frame format, receiver stations on the same bus as the transmitter station can be addressed with very low overhead.
