Abstract

The present invention refers to a method and a device for determining a parameter (v) that characterizes a number of spare positions to be used for cancelling the crosstalk of lines (13) joining a digital subscriber line vectoring group, the vectoring comprising cancelling the crosstalk caused by a maximum number (M) of lines (13) of the vectoring group and reserving said number of spare positions. In order to to provide a method and a device for determining a number of spare positions such that the vectoring group operates efficiently, it is suggested that the method (51) comprise determining (57) a residual crosstalk metric (± a ) that depends on a residual crosstalk between at least two subscriber lines (13) of the vectoring group; and determining (67, 69, 79) said parameter (v) that characterizes the number of spare positions depending on the at least one residual crosstalk metric (± a ).
