PURPOSE:To execute tests of many local node devices with high efficiency by switching these node devices by a command given from a center node device. CONSTITUTION:A return test part 605 is set between a terminal equipment 504 and an interface part 605 and is provided with functions to separate the equipment 504 from a node device 503 by an indication of a monitor control part 604 and also to return the test data. A test return part 708 is set between the equipment 504 and an interface part 703 and is constituted so as to separate the equipment 504 by a command of a control part 704 and to return the test data. When the designation is given from an input device 706, a control part 705 gives test instructions to the part 704, the part 703, the part 708 and a test part 709 respectively and separates a designated circuit from the equipment 504. Thus the test data can be supplied from the part 709. |
