摘要： A looped bus system includes several nodes connected by unidirectional buses having opposite directions of signal transmission. The head of bus function for each bus is located at a node different from the head of bus function for the other bus. The head of bus function for each bus is located at the same node as the termination of bus function for the other bus. As a result, the buses can be reconfigured and nodes can be added freely by the use of a bus portion that is unused in the looped bus under normal condition.

摘要： Distributed LANs are connected to a wide area network through terminal adapters, which are interconnected by virtual circuits to form a logical bus network. Each terminal adapter copies cells received through the virtual circuit that is allocated for multicasting, and transfers the copied cells to the adjacent terminal adapters via preset virtual circuits. The terminal adapters assemble a part or all of the transmitted message from the received cells and, according to the contents of the assembled message, transfer the copies of the cells to the adjacent terminal adapters through predetermined virtual circuits.

摘要： In a cell delineation circuit, an input signal is converted into parallel signals, and a plurality of parallel signals (i.e. series of parallel signals) which are shifted one bit by one bit from each other are formed from those parallel signals. CRC (Cyclic Redundancy Check) calculations are executed in parallel for the plurality of parallel signals. A series in which a pattern to be calculated satisfies a CRC rule is determined from results of the CRC calculations, and this series is generated, thereby establishing a cell delineation.
