Title: Storage device
Inventor: SATO TOSHIHIKO
IPC: G06F11/22
Filed: 1986-03-24
Abstract: PURPOSE:To early detect the fault of an error correction detecting circuit by putting an error into a write checking bit to correct this error by an error correction detecting circuit and detecting the presence/absence of an error again for the corrected data by the error correction detecting circuit. CONSTITUTION:A write checking bit WH is inverted by an inverting circuit 15 based on a test pattern produced by a test pattern generating circuit 14. A test check bit WT containing an error is supplied to an error correction detecting circuit 17 together with write data WD. The correction data CD outputted via a syndrome generating circuit 171, a decoding circuit 173 and a correction circuit 174 is corrected as if the bit WT were correct and the data WD had an error after the bit containing an error is inverted to the data WD based on a test pattern TD. Therefore, a state free from error is detected as long as no fault exists by supplying the data CD again to the circuit 17 together with the bit WT via a read data register 18.

Abstract: PROBLEM TO BE SOLVED: To reduce the spreading extent of a failure of one optical subscriber unit to other optical subscriber units by sending a stop signal which is undergone wavelength multiplexing to signal light having wavelength that is different from wavelength of signal light which has a communication failure from a station unit to each optical subscriber unit, selectively stopping an optical subscriber unit and specifying a subscriber unit that has a failure. SOLUTION: When the communication of wavelength λ1 becomes impossible, an OSU 18 which terminates an optical transmission path on a station side sends a control signal which stops the sending of a communication signal to optical subscriber units ONU 20 in turn by using a down signal of wavelength X2, and each ONU 20 receives a control signal and shuts down an up light signal to the OSU 18. When ONUs 20 are successively shut down, the communication of the wavelength λ1 is restored at the time of shutting down the ONU 20 that has a failure. With this, the ONU 20 that has a failure is specified, and the communication of the waelength λ1 is secured except the ONU 20 that has the failure by eliminating the ONU 20 that has the failure.
