Abstract

PURPOSE:To achieve the bracketing of a fault position by testing a circuit side and an exchange side independently by switching a trunk circuit package and a testing device. CONSTITUTION:To the package position 7 of a trunk package to be tested, a testing device 6 having a circuit-side testing terminal T0 and an exchange-side test terminal T1 is connected. A call line from the exchange-side test terminal T1 is connected to a signal transmitting and receiving means 1, and a control line to a controller 3. Consequently, the circuit side and exchange side are tested independently of each other. The operation characteristics of a trunk circuit to be tested are confirmed by testing the trunk circuit to be tested. Thus, a fault point is discriminated easily for the test of the operation characteristics of an exchange system.
