Vectoring cancels the crosstalk between multiple VDSL2 lines and can greatly improve performance, particularly on short loops. Crosstalk cancellation can only be performed on lines within a vector group and vectored lines may experience uncancelled crosstalk from nearby lines that are non-vectored or in a separate vector group. This paper shows that a substantial consensus exists on the possibility of mitigating the impact of this uncancelled crosstalk on the vectored lines. Among the possible

... itigation techniques, we show here that very good levels of compatibility between vectored and non-vectored VDSL2 can be achieved with Dynamic Spectrum Management (DSM]).
