Abstract

PURPOSE:To form a star LAN which enables a subscriber line rate and a data bus rate to be set independently and has a fast data bus by providing a bus access unit with a transmitting buffer and a receiving buffer. CONSTITUTION:A bus system consists of a delimiting bus 31, a RNR(Receive- Not-Ready) bus 32, a data bus 34 for packet signal transfer, and an arbitor bus 33 which specifies one bus access unit among bus access units requesting transmission. The bus access units 10 and 20 each consist of an address filter 1, a receiving buffer 2, a transmitting buffer 3, a bus access control circuit 4, and a subscriber terminating circuit 5. Thus, the transmitting and receiving buffers 2 and 3 are provided, so the subscriber line rate and data bus rate are independently settable and the fast data bus is obtained.
