Abstract: Embodiments of the present invention relate to the field of communications and disclose a method and an apparatus for grouping line pairs, and a system, to solve a problem that obtaining a crosstalk cancellation coefficient matrix through channel training imposes a very high requirement on a system capability such as a computing capability and a storage capability and even affects user experience due to the relatively large number of line pairs in a large scale Vectored-DSL system. A technical solution provided in the present invention includes: acquiring crosstalk impact data between line pairs in a vectored-digital subscriber line Vectored-DSL system; and grouping line pairs, between which a crosstalk impact cannot be ignored, into one vector group according to a set threshold and the crosstalk impact data between the line pairs. The method and apparatus provided in the embodiments of the present invention are applicable to a large scale Vectored-DSL.
