Data transmission equipment

Abstract

Abstract PURPOSE:To send an object transmission data to an object district without notifying a faulty communication destination from a sender by transferring a reception data to a standby processor until the fault is released when a data transmission equipment detects a fault of the own processor. CONSTITUTION:When signal lines 504, 510 of a processor fault display register 503 show processor fault, a selection circuit 514 connects signal lines 513, 511 and a selection circuit 508 connects signal lines 507, and 518. Thus, the data on the signal line 513 is outputted to the signal line 511 through the selection circuit 514, a transmission destination address in the reception data is replaced by an address of the standby processor address register 505 and outputted to the signal line 507. The data addressed to the standby processor is inputted to a data transmission line transmission circuit 509 through a signal line 518 and outputted to a signal line 901 from the circuit 509. If the processor 1 is failed, the reception data is transferred to the standby processor.
