PURPOSE: A device for processing an ATM layer and a method therefor are provided to perform a header conversion of an ATM cell by using user parameter monitored results and connection information, and to carry out a performance monitoring function, thereby implementing the device as one hardware at fast processing speed. CONSTITUTION: A receiving connection identifier manager(100) obtains a connection identifier by using a VPI, a VCI, and a line number, converts an ATM cell in cell type, and transmits the ATM cell, the line number, a connection type, and the connection identifier. A user parameter monitor(200) monitors a user parameter by using the connection information when the ATM cell, the line number, the connection type, and the connection identifier are received. A receiving header conversion and performance monitor(300) performs a header conversion of the ATM cell, and monitors performance by using user parameter monitored results and the connection information.
