An architecture of optical passive bus for broadband CPN (customer premises network)

The authors discuss the broadband customer premises network (CPN) configuration for B-ISDN (broadband integrated services digital network) and propose an optical passive bus scheme with ATM (asynchronous transfer mode) access. To confirm the feasibility of the optical passive bus, the authors studied optical level diagrams and the collision on ATM multiple access. Novel techniques of level control and collision control are introduced. An intra-CPN communication scheme is also proposed. An optical passive bus scheme with multipoint connections and possible application to CCITT standards is also shown.<
