Communication apparatus, private branch exchange apparatus, maintenance terminal apparatus, and simulation method

摘要

A simulation program in which a step of allowing a maintenance terminal to simulate control process contents concerning an exchange among a plurality of extension terminals written in an application program is written is stored in a storage section disposed in a private branch exchange apparatus, and a CPU displays a model indicating the plurality of extension terminals and the whole private branch exchange apparatus in a display of the maintenance terminal and allows the maintenance terminal to operate based on the simulation program stored in the storage section and execute the control process contents written in the application program with respect to the model displayed in the display, when a simulation mode is set.
