PURPOSE: A line call generator is provided to test a data traffic processing function and a call processing function of the interworking function system(IWF). CONSTITUTION: The line call generator includes a link line matching part(250), a line data processor(220), a control bus, a data bus, and a controller. The link line matching part is matched with a radio data service device for connecting a cordless network with the cord network, and performs a switching by a communication between a line call generator and a radio data service device. The line data processor is connected to the radio data service unit through the link line matching part, and emulates a role of a cordless subscriber and a cord subscriber. The control bus transmits a control signal to the link line matching part and line data processor. The data bus transmits a data to the link line matching part and the line data processor. The controller controls an operation of the line data processor. Thereby, a data traffic processing function and a call processing function are tested, a capacitance of the data service unit is tested, and a production cost is reduced.
