A circuit call generator (load box) for functional testing of interworking function (IWF) system and a method for testing the functions of the IWF system are provided. The circuit call generator includes a trunk interface unit for performing communication channel switching between the call generator and the IWF system, a circuit data processing unit for performing emulation of a role of the wireless subscribers or wired subscribers, a circuit data processing unit being connected to the IWF system via the trunk interface unit, a control bus for transmitting control signals between the trunk interface unit and the circuit data processing unit, a data bus for transmitting data between the trunk interface unit and the circuit data processing unit, and a control unit for controlling the emulation of the circuit data processing unit. |
