PURPOSE: A system for operating and configuring an AAL2/5 conversion unit for the improvement of transmission efficiency in interoffice connection in IMT-2000 service is provided to reduce the quantity of logics for AAL2/5 conversion. CONSTITUTION: A system for operating and configuring an AAL2/5 conversion unit(2) for the improvement of transmission efficiency in interoffice connection in IMT-2000 service consists of a conversion control unit(1), the AAL2/5 conversion unit(2), a system access unit(3), and a transmission line access unit(4). The conversion control unit(1) issues a speech path control command for the transmission of subscriber information according to a radio subscriber's conversion address request generated from the AAL2/5 conversion unit(2) or a subscriber transmission request received from the transmission line access unit(4), and manages and monitors the state of information transfer. The AAL2/5 conversion unit(2) receives a conversion control command from the conversion control unit(1), makes the transmission line access unit(4) establish a speech path, and executes an AAL2/5 conversion processing function. The system access unit(3) receives AAL5-type data according to the control of the conversion control unit(1) and transfers the received data to the AAL2/5 conversion unit(2). The transmission line access unit(4) executes a function to establish an appointed speech path according to the command of the conversion control unit(1).
