PURPOSE:To conduct a test efficiently by connecting numbers of circuits to be tested between an automatic test controller and a main distributing board, and connecting the automatic test controller to a switchboard controller. CONSTITUTION:The automatic test controller 7 which controls the test automatically is provided and connected through the switched controller 5 and a connector 9; and the automatic test controller 7 and main distributing board 2 are connected mutually by a connector 8 which connects numbers of circuits, and numbers of circuits to be tested are connected on multiple basis between the automatic test controller 7 and main distributing board 2. Consequently, numbers of circuits to be tested are connected between the main distributing board 2 and automatic test controller 7 and connections of circuits to be tested are changed automatically according to a program to conduct the test. |
