Abstract

PURPOSE:To make the failure sectioning easy at failure generation, by providing functions identifying and displaying a complaint and application code from a terminl and that making interrupting test with a video information service center using a public telephone network. CONSTITUTION:A keyboard 1 for information input and a video display device 2 are controlled with a terminal controller 3, and input/output information is connected to a telephone exchange network 7 via a modulation and demodulation device 4 and a line connection device 5. On the other hand, at the center side, a communication controller 11 is connected via a test spring 8, an input trunk 9, and a modulation and demodulation device 10, and the reception of an input signal and the transmission of video information are made through the control of a center processor 12. When a subscriber detects a failure at the production of failure, after a telephone set 6 is off-hooked and a complaint application code is inputted from the board 1, it is displayed on a display device 17, allowing to inform the failure via a telephone set 14. Further, a line changeover switch 13 is switched and the monitor test of recetion data and the transmission of test picture can be made by using a test device 16.
