Method for automatically removing crosstalk and an apparatus thereof

A method for automatically removing a crosstalk between a G.fast system and a transmission line on a generic interface, by means of a processor executing instructions stored in a memory device, wherein the G.fast system has a first G.fast subcarrier corresponding to a minimum G.fast frequency and a second G.fast subcarrier corresponding to a maximum G.fast frequency, and a plurality of G.fast subcarriers exist between the first and the second G.fast subcarriers, the method comprising:

• measuring a plurality of loop diagnostic metric data related to a communication loop connected between a G.fast distribution point unit (DPU)/digital subscriber line access multiplexer (DSLAM) equipment and a G.fast customer premises equipment (CPE) by the G.fast DPU/DSLAM equipment;
• inspecting the plurality of loop diagnostic metric data corresponding to the plurality of G.fast subcarriers between the first and the second G fast subcarriers;
• simulating a loop diagnostic metric simulation graph having plural graph points corresponding to the plurality of G.fast subcarriers and related to the communication loop in an absence of the transmission line, wherein a specific one of the plurality of loop diagnostic metric data corresponds to a specific one of the plural graph points, and a specific one of the plural graph points corresponds to a specific one of the plurality of G fast subcarriers;
• comparing the specific one loop diagnostic metric data and the specific one graph point corresponding to the specific one G.fast subcarrier to obtain a difference;
• when the difference complies with a degradation criterion of communication data flow quality, recording the specific one G.fast subcarrier, wherein the degradation criterion of communication data flow quality is established based on a sudden degradation resulting in at least one of a non-sustained link and a packet loss in the specific one G.fast subcarrier;
• and
• masking the recorded specific one G.fast subcarrier.
