摘要： PURPOSE:To shorten time till the control task of a control unit inside a monitoring device judges that a FAIL occurs at the time of the FAIL of a serial interface unit by providing an alarm monitoring task inside the control unit of the monitoring device. CONSTITUTION:The monitoring device A is provided with the control unit B and the serial interface unit C. The control task (a), a dual port MEN-b and the alarm monitoring task (c) are provided inside the control unit B. N devices to be monitored D-n are connected to the serial interface unit C so as to constitute a monitoring system. When the FAIL occurs in the serial interface unit C, FAIL information is transmitted from the alarm monitoring task (c) to the control task (a). Thus, time for judging that the FAIL occurs by the control task (a) is shortened.

摘要： PROBLEM TO BE SOLVED: To obtain an optical wave ring system that can apply a protection function only to a faulty wavelength even on the occurrence of the fault of the part wavelength in a point-to-point wavelength multiplex transmission system. SOLUTION: Each of 1st-4th nodes 101-104 is provided with wavelength multiplex/demultiplex sections 132, 133. An optical wave ring device 131i with respect to a wavelength λi is installed to 1st-3rd nodes 101-103, and an optical wave ring device 131j with respect to a wavelength λj is installed to 2nd-4th nodes 102-104. Clients 135 are connected to the optical wave ring devices 131i and 131j. Thus, the system takes a unique ring configuration as to each wavelength (two wavelengths only are explained above). Each of the optical wave ring devices 131i and 131j is provided with a wavelength conversion section and an overhead termination section, and when the overhead termination section detects a fault as to a transmission path of a wavelength being a prescribed block, the overhead termination section recovers the fault of each corresponding wavelength. The wavelength conversion section can optionally change the wavelength given to or outputted from the fiber.

摘要： PROBLEM TO BE SOLVED: To obtain a signal management system capable of high-speed fault recovery at low costs by eliminating a complicated logic circuit for specifying a location of a fault in a wavelength multiplexed network. SOLUTION: As a form of an optical signal to be transmitted, an optical signal form provided with a region for managing the quality of optical transmission, namely, provided with an optical transmission management byte therein is used. A parity of the transmitting signal is stored in the optical transmission management byte. The transmitted optical signal is inputted to a photoelectric transduction part 101 and inputted to an optical transmission management byte terminating part 103 after applying 3R processing thereto in a 3R processing part 102. The parity stored in the transmitted optical transmission management byte is compared with a parity of a received signal to calculate the number of bit errors and a bit error rate. In order to calculate the bit error rate in the next node, before subsequent optical transmission to the other node, the parity of the signal is calculated in an optical transmission byte generating part, and the result is stored in the optical transmission management byte.

摘要： PROBLEM TO BE SOLVED: To suppress latency rate of a fault and to suppress the occurrence probability of a system down. SOLUTION: At first and second disk devices 3 and 4, a self-diagnostic program is executed repeatedly at prescribed intervals, and when the execution of prescribed processing is instructed, this processing is executed by stopping the self-diagnostic program. When the processing is finished, the execution of the self-diagnostic program is started again. When a fault is detected at the first disk device 3, for example, this fault is reported to a main processor 1 and as slave processor 2. Thus, the main processor 1 switches a processing object only to the second disk device 4 where no fault is occurring.

摘要： PURPOSE:To deal with a case modification of a program is required wit least exchange of ROMs by disposing respective object modules to be connected so as not to bridge plural ROMs to connect them, and securing an area for program patch in the respective ROMs. CONSTITUTION:A link editor main part 101, for allocating to individual memories, combine designated object modules and connects them together, however, at this time, a module allocating part 104 combines the modules most suitably so that an area in a size closes to the size of a vacant area for one piece of ROM is remained in each ROM. Based on the result of such allocation, the part 101 re-generates a command file, then connects the object modules in accordance with the new command file. As a result, in the event of a need for modifying an object module and when the modification can not be processed within an original program area, it can be dealt with by a vacant area 15 for patch on the same ROM 9.
