RADIO INTERFACE UNIT FOR INTERFACING PLURAL SUBSCRIBERS AND CONTROL METHOD THEREOF IN WIRELESS LOCAL LOOP

摘要

PURPOSE: A radio interface unit for interfacing plural subscribers and a control method thereof in wireless local loop(WLL) are provided to match terminals of plural subscribers to a radio interface unit, thereby increasing the effectiveness of hardware sources. CONSTITUTION: A base station matching unit(115) matches the base station of WLL, and detects ring and interfaces the data transceived with the terminals of the subscribers. A codec(112) modulates the data received from the base station matching unit by PCM(Pulse Code Modulation) and demodulates the data received from the terminals of subscribers by PCM. A subscriber's line interface card(117) constitutes a communicating line by interfacing the terminals of the subscribers with the codec according to a predetermined control. A control unit(111) detects the telephone numbers of subscribers included in the detected ring signal and selects the subscriber's line interface cards corresponding to the telephone numbers. Especially, the control unit(111) selects the subscriber's line interface card of hook-off state and then constitutes a communicating line.
