PURPOSE: A method for testing the performance of the radio interface unit for the WLL(Wireless Local Loop) system is provided to carry out performance tests for an RF processing unit, a digital processing unit, a subscriber interface, etc., in the radio interface unit, using DTMF signals. CONSTITUTION: A processor(24) executes switching control for the loopback mode of a transmitting-receiving part(21), the loopback mode of a modulation/demodulation part(22) and the loopback mode of a transcoder(23) to set up. A keypad(25) inputs command data to set up the loopback modes and to carry out the operation performance test of each of the units. A monitor(26) displays a result for the operation performance test of each of the units. |
