<p>Embodiments of the present invention disclose a method and a related device and system for crosstalk cancellation processing on a port line of an access device. The method for crosstalk cancellation processing on a port line of an access device includes: obtaining line configuration information of another access device connected to an access device, where the line configuration information includes line operation parameters and a line group identifier of at least one port line, and line group identities of different port lines belonging to a same cable bundle are the same; respectively obtaining, by the first access device, according to the line configuration information of the another access device, a coefficient of an effect from a port line of the another access device having a same line group identifier as that of a local port line on the local port line; and performing crosstalk cancellation processing on the local port line on the basis of the obtained effect coefficient. The technical solutions provided by the present invention can satisfy a scenario in which subscribers on a same cable bundle are connected to different access devices.</p> |
