Abstract: PURPOSE: A method for supplying attenuation value information by port in a 2-band VDSL(Very high-date rate Digital Subscriber Line) is provided to receive a transmit power from a DSL(Digital Subscriber Line) modem to measure an attenuation value of a line, and to supply the measured value to a manager, thereby effectively operating and maintaining a VDSL system. CONSTITUTION: A management system stores standard transmit power by frequency(S21), measures attenuation values(S22), and requests a management object to send transmit power values according to each port(S23). When the transmit power values are inputted(S24), the system obtains usage frequency information of the ports(S25), and retrieves a standard transmit power of the corresponding usage frequency(S26). The system subtracts the standard transmit power of the frequency from the transmit power values of the ports(S27), and estimates a difference(S28), then stores measured time, frequency, and attenuation information(S29). If an attenuation average value or a sum of certain times is requested(S30), the system calculates the average value and the sum, and supplies the calculated results to a management support system or a manager(S31).
