Abstract: An information processing device includes a first recording medium, a first storage unit, a second storage unit, and a processor. The first recording medium stores data in a first format. The first storage unit stores a first program for causing the device to access data in the first format and not causing the device to access data in a second format different from the first format. The second storage unit stores a second program for causing the device to access data in the first format and causing the device to access data in the second format. The processor is configured to select one of the first program and the second program and execute, upon selecting the second program, the second program to read first data stored in a second recording medium in the second format and write the first data in the first recording medium in the first format.

Abstract: There are disclosed a mounting information-collecting device which is capable of collecting mounting information concerning mounted statuses of circuit boards with high accuracy and efficiency, as well as a connector and a mounting information-collecting method therefor. A light-emitting device emits an optical signal. A plurality of optical signal-processing elements each apply processing to the optical signal in a manner unique to a corresponding one of the circuit boards to thereby generate a processed optical signal. A mounting information-collecting device receives the processed optical signal and detects whether or not the processing has been applied, to thereby collect the mounting information.

Abstract: In a node device switching over a working system to a protection system at the time of a fault occurrence, a relative phase difference detector detects a relative phase difference of transmission delays of a working transmission line and a protection transmission line, a path error detector detects path errors on the transmission lines, and a main signal error calculator calculates errors of the main signals from the transmission lines, thereby specifying a position on which the fault has occurred based on the path errors and main signal error calculation results which are made in phase based on the relative phase difference.

Abstract: A time switch control system having a cross-connect function is used for digital time-division. Multiplex communications permit desired channel settings and reduce power consumption. Identifying circuits identify which time-slot signals are to be retained by an input signal retaining memory, and output identification information to the retention memory, and to a retention memory controller. The retention memory controller stores therein the identification information from the identifying circuits, then reads out the identification information, and controls the input signal retaining memory in accordance with the contents of the identification information. Only the specified time-slot signals are stored and retained by the input signal retaining memory, thereby reducing power requirements. Exchange/output circuits exchange the time-slot signals stored in the input signal retaining memory in accordance with channel setting information, and output the exchanged signals.
