DATA TRANSMISSION ARRANGEMENT INCLUDING A RECONFIGURATION FACILITY

摘要

46 "Data transmission arrangement including a reconfiguration facility." The construction of an arrangement for data transmission between a number of interconnection units should be realized so that, after a disturbance, an extensive as possible reconfiguration of the arrangement is possible, so that all interconnection units which still communicate via a connection are interconnected by means of transmission paths which merely follow a different course in comparison with the non-disturbed state. In accordance with the invention each interconnection unit is provided with a device for generating synchronization information and in the case of a disturbance, appearing as a breakdown of the normal data stream, all interconnection units enter a test state in which test information is transmitted and possibly received test information is returned via all connections. Consequently, in each interconnection unit it can be autonomously decided which data paths are to be interconnected. In the case of at least three data connections per interconnection unit, different configurations are feasible which enable a complete reconfiguration to be realized also in the case of multiply disturbed connections between the interconnection units.
