An optical telecommunication apparatus includes a shelf, a primary substrate provided in the shelf, a secondary substrate provided on the primary substrate, an optical component provided on the secondary substrate, and an optical connector provided on the secondary substrate for connection with an external optical cable, wherein the secondary substrate is pivoted on the primary substrate about a pivot axis so as to be movable about the pivot axis between a first position in which the secondary substrate is inside said shelf and a second position in which the secondary substrate projects outside of the shelf. The secondary substrate is in electrical connection with the primary substrate while in any position between the first and second positions.

A power supply terminal that prevents damage to capacitors included in a noise filter circuit therein which may occur due to a BWB's warp or thermal stresses at soldering time. The noise filter circuit is formed on a noise filter circuit substrate, being a substrate separate from the BWB. The noise filter circuit substrate is connected conductively to part of each of press fit terminals.

An electronic apparatus includes an optical connector adapting unit to which optical connectors of external optical fibers are connected. The optical connector adapting unit includes a plurality of optical connector adapters which are diagonally arranged on the front side of the apparatus. The optical connectors of the external optical fibers are diagonally detachable from the optical connector adapters. In this electronic apparatus, a large number of optical connectors of optical fibers can be connected and arranged in a restricted space.

An SFP module mounting structure whereby the region of a printed wiring board for mounting SFP modules is enlarged and thus the SFP modules can be mounted with high density. A swing mechanism constituted by the coupling between a holder and a base allows the holder to be swung in directions toward and away from the printed wiring board. Thus, when mounting an SFP module, the SFP module can be inserted into the holder with the holder kept in an obliquely raised state relative to the printed wiring board. Also, when detaching the SFP module, the SFP module can be pulled out of the holder with the holder obliquely raised from the printed wiring board.

An ISDN switching system having facilities for testing an ISDN signal composed of B-channels and D-channels at least. The testing facilities can achieve a B-channel test and D-channel test selectively with simple construction by employing a converting unit in the system. The converting unit enables creation of a connection path between a test equipment and an object to be tested through an ISDN exchange and thus the ISDN signals for the test can be treated as usual ISDN signals. Thereby, the test equipment and the object can freely be connected to each other.

An instruction file execution device which includes a receiver, a comparison section and a job execution section. The receiver receives an instruction file and a usable money amount, which instruction file describes a job flow which defines linking of a number of jobs. The comparison section compares an execution charge of a job being handled of the jobs of the instruction file received by the receiver with the usable money amount received by the receiver. If the comparison section determines that the usable money amount is greater than or equal to the execution charge, the job execution section executes the job being handled.
