ABSTRACT:
A system for generating calls in order to test telephone switching systems by simulating traffic loads has line interface circuits which send calls independently and in selected sequence on any number of a group of lines into the telephone switching system under test. Lines of the telephone switching system which are supposed to be called are terminated by the interface and outputs representing the successful completion or failure to complete calls are obtained. Commands for controlling the generation and termination of calls are generated under microprocessor control. DTMF originating and dial tone detecting circuits as well as circuits for transmission and loop polarity testing may be added to the line interface and controlled by the same microprocessor. The system has a microprocessor controlled display and keyboard terminal by means of which instructions for and reports of the results of the tests are obtainable.
