System for controlling international mobile telecommunications - 2000 (IMT-2000) base station

摘要

A system for controlling an international mobile telecommunications - 2000 (IMT-2000) base station includes: 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.
