Claim Text:
1. A method for crosstalk cancellation processing on a local port line interconnecting at least two access devices, the method comprising: obtaining, by a first access device of the at least two access devices, line configuration information of a second access device of the at least two access devices, wherein the line configuration information comprises line operation parameters and a line group identifier of at least one port line, and wherein line group identities of different port lines belonging to a same cable bundle are the same; obtaining, by the first access device, one or more effect coefficients according to the line configuration information of the second access device, the effect coefficients corresponding to one or more port lines of the second access device having a same line group identifier as the local port line; and performing crosstalk cancellation processing on the local port line in accordance with the effect coefficients.
