Abstract:
1. A system for controlling an international mobile telecommunications—2000 (IMT-2000) base station, comprising: a base transceiver station (BTS) for providing asynchronous transfer mode (ATM) cells; an asynchronous transfer mode (ATM) switch for performing a switching of the ATM cells; and a BTS interface subsystem (BIS) for interfacing the base transceiver station (BTS) with the asynchronous transfer mode (ATM) switch, wherein the BTS interface subsystem (BIS) includes a plurality of assembly symbol subsystems (ASSs) for receiving the ATM cells transmitted from the base transceiver station (BTS) and performing a type conversion of the ATM cells to output a type converted ATM cells to the asynchronous transfer mode (ATM) switch, wherein the ASS includes: a processor for controlling an operation; a reception (RX) multiplexer for classifying the ATM cells into first ATM cells corresponding to internal signals to the processor and second ATM cells corresponding to remaining ATM cells, wherein the first ATM cells are transmitted to the processor; a reception (RX) type conversion unit for receiving the second ATM cells and classifying the second ATM cells into ATM adaptation layer a transmission (TX) multiplexer for outputting the first ATM cells and the second ATM cells, the first ATM cells being transmitted to the processor; and a transmission (TX) type conversion unit for classifying the second ATM cells transmitted from the transmission (TX) multiplexer into AAL
