Abstract

PURPOSE:To recognize the state of a subscriber informing generation of a fault by drawing an optional unit channel commanded from the operation panel to a test use subscriber circuit, connecting a test use telephone set and displaying the control state and the line state of the subscriber corresponding to the operation panel. CONSTITUTION:A maintenance personnel connects the test use telephone set 6 to a test use subscriber circuit 2-8 and an optional subscriber is selected by an operation channel 2-7 and a changeover switch 2-9. In commanding the incoming test to the corresponding subscriber, a control section 2-1 monitors the test use subscriber circuit 2-8, operates a signal bit of a channel to the corresponding channel to send a call signal in detecting off-hook. In this case, the state of the subscriber and the state of the signal bit to the subscriber are displayed on an operating panel 2-7 and when the subscriber responds thereto, the signal bit to the speech state is controlled. Thus, a fault is located easily.
