Abstract

PURPOSE:To make the addition of a new transmitting station easy by inserting a data branching and inserting device, when the transmitting station is desired to be added. CONSTITUTION:Transmission stations 1 and 4 are connected to a reception station 2 via a data branching and inserting device 9. In the communication from the station 1 to the station 2, the information representing the station 1 is added to an address field of a frame 10 transmitted from the station 1 in advance. When the device 9 receives this frame 10, it is transmitted to the station 2 as it is. The reception station 2 recognizes that the received frame comes from the transmission station 1 by analyzing the address field of the received frame 10. This is the same as the transmission from the transmission station 4. If the frames 10 and 11 corride with each other at the device 9, the corrision is processed at a waiting buffer provided at the device 9.
