CALL SIMULATOR OF FULL ELECTRONIC EXCHANGE

摘要

PURPOSE: A call simulator of a full electronic exchange is provided to test performance and verify software functions without physically connecting a call generation equipment with a subscriber, as having mounted information of a present system, and to analyze tested results as statistic data, thereby analyzing package performance and reducing testing time. CONSTITUTION: An analog subscriber interface simulator(ASI_ASIP)(100) simulates an analog subscriber interface function, and stores a simulated result. A digital subscriber interface simulator(DSI_ISAP)(110) simulates a digital subscriber interface function, and stores a simulated result. A virtual switching interface simulator(VSI_NSI)(120) simulates a virtual switching interface function, and stores a simulated result. A trunk interface simulator(TI_TIP)(90) simulates a trunk interface function, and stores a simulated result. A signal message management processing simulator(SMHP)(130) simulates a signal message managing function of mobile communication, and stores a simulated result. An overall operation and maintenance simulator(SIM_OMP)(20) selectively starts simulation operations of the ASI_ASIP(100), the DSI_ISAP(110), the TI_TIP(90), and the SMHP(130), and receives message processing results from the simulators(100,110,120,90,130).
