The present invention allows the WLL system to satisfy the WLL radio access standard while allocating D-channel to the minimum channel when connecting to the V5.2 and the BRI junction of the WLL switch, and modularizing the mounting board for system maintenance and The present invention relates to a device for allocating a channel to a minimum channel for a non-eye service in a wireless subscriber network system for easy scalability, and to converting an analog signal (A) input from the RFU (1) into a digital signal (D). A / D and D / A signal converters (2) and (3), which convert the digital data received from the modem into analog data to the RFU (1), and the signal converter (2) (3). D-channel in the data coming out through the first and second modem unit (4) (5) and the first and second modem unit (4) (5) for code division conversion of the data input from To find and collect these four into one 64Kbps channel CPU (7) and the CPU (7) which frame the data received from the channel handler / HDLC controller (6), the channel handler / HDLC controller (6) to perform IPC communication and controls the entire block A memory (8) connected to the memory (8) for temporarily storing variables or data, an IPC interface (9) connected between the CPU (7) and the main processor (12) to perform IPC communication, and the first and second It consists of mux / demux 10 which makes 64Kbps data output through 2 modem (4) (5) to 2.048bps.
