ABSTRACT:
A method for connecting a first communications system with a second communications system is disclosed. A first frame is received at a first station. The first station is connected to both the first communication system and the second communication system. The first frame has a destination address field, and the destination address field contains a desired destination address. The first station forwards, in response to the desired destination address, the first frame onto the second communications system as a second frame, and the first station writes a second destination address into a destination address field of the second frame. The first station writes the desired destination address into a predetermined field of the second frame. The first station writes, an indicator into the second frame, the indicator is capable of being interpreted by a receiving station to mean that the desired destination address is written into the predetermined field of the second frame. The receiving station receives the second frame. The receiving station is also connected to a third communications system. The receiving station reads, in response to the indicator, the desired destination address from the predetermined field of the second frame, and writes the desired destination address into a destination address field of a third frame. The receiving station forwards the second frame onto the third communications system as a third frame.
