Test method at extension of communication terminal station equipmetn

Abstract

PURPOSE: To improve the reliability of a test at the extension of a communication terminal station equipment by conducting the test of transmission/reception of state information and a control signal even between a simulator and an information collection controller. CONSTITUTION: While a monitor control communication line 11 is connected to a communication terminal station equipment 5 at the extension of the communication terminal station equipment 5 to bring the state not giving the effect onto other communication terminal station equipment, and state information representing a fault is sent to an information collection controller 10. Then a control signal representing not giving any effect onto other communication terminal station equipment is sent from the controller 10 to the equipment 5 to conduct the test of transmission/reception of state information and control signal representing giving no effect onto the other communication terminal station equipment. Then a simulator 12 is connected to the signal line 11 to allow the simulator 12 to generate state information representing a fault giving effect onto other terminal station equipment and to send it to the controller 10, and the controller 10 sends a control signal giving effect onto the other communication terminal station equipment, the control signal is displayed on the simulator 12 to conduct the test of transmission/reception of the state information and the control signal giving effect onto the other communication terminal station equipment.
