ABSTRACT:
A redundant (multiple) bus system for interconnecting a plurality of data source and destination entities and arranged to direct data communications over an alternative bus in the event that a prior call to a destination over a first bus was unsuccessful. Each source entity maintains a table designating a separate logical path over each bus to each destination entity, marking each path designation in accordance with the success or failure of calls directed through the path. The bus selection for delivering a communication to any destination is determined in accordance with designation markings for the paths to the destination and independent of designation markings for paths to other destinations whereby a bus may be selected for a delivery to one destination even though prior deliveries over the bus to other destinations have failed.
