PURPOSE: An apparatus for allocating dechannel to minimum channel for BRI(Basic Rate Interface) service in WLL(Wireless Local Loop) system and the method thereof are provided to achieve easily system maintenance and scalability by providing digital unit and 2W BRI interface unit to allocate D channel to minimum channel for connecting the V5.2 of WLL mobile switching center and the BRI matching apparatus. CONSTITUTION: Signal conversion parts(2,3) converts digital data received from a modem into analog data to RFU(1). A first modem part(4) and a second modem part(5) converts data inputted from the signal conversion parts(2,3) into desired data pattern by code division conversion. A channel handler/HDLC controller(6) finds out D channel in data through the first modem part(4) and the second modem part(5), and makes into a 64 Kbps channel, collecting 4 nos. channels. A CPU(7) proceeds control for overall block. A memory(8) connected the CPU(7) stores variable and data temporarily. An IPC interface unit(9) connected between the CPU(7) and a main processor(12) processes to proceed IPC communication. A MUX/DEMUX(10) makes the 64Kbps data into 2.048bps.
