ABSTRACT:
The bus connection structure for an interruption control system consisting of, in a single cabinet, processors and at least one input/output control adapter connected to each processor includes elongated connectors having an identical structure and being arranged parallel to each other on a backboard provided inside the cabinet. Each connector has two terminal arrays consisting of identical numbers of terminals along the longitudinal direction. The connectors have one-to-one correspondence with the processors and the adapters. The connectors corresponding to the adapters which belong to a given processor are sequentially arranged on one side of the connector corresponding to the given processor. The interconnector wirings are formed on the backboard to be parallel to each other so as to connect opposing terminals of the adjacent connectors in one-to-one correspondence. The internal wirings are formed between the two terminal arrays of the connectors excluding those corresponding to the processors so that a predetermined number of terminals in the connectors corresponding to the adapters and a predetermined number of terminals in the connector corresponding to the given processor are connected to each other through the internal wirings and the interconnector wirings.
