Abstract: The invention relates to a method for improved performance for access multiplexing on networks with metallic pairs comprising the steps of: - dividing ultra-broadband transmission frequencies into non- overlapping frequency blocks containing sub-carriers; - allocating said frequency blocks to separate operators; - applying interference suppression techniques to said frequency blocks. The invention also relates to a system adapted to implement this method, by means of at least one SBV DSLAM apparatus comprising: - a FEXT pre-coder provided with means adapted to determine FEXT for downstream transmissions; - a FEXT canceller provided with means adapted to determine FEXT reduction for upstream transmissions; - an SBV control unit, associated with said FEXT pre-coder and canceller, - an I/O interface, comprising means adapted to allow the connection of a plurality of SBV DSLAM apparatuses to one another, wherein said elements cooperate to determine the division of transmission frequencies into frequency blocks, non-overlapping and containing sub-carriers, allocated to separate operators and individually subject to interference suppression techniques, so as to allow the implementation of ultra-broadband transmissions by several operators co- located on the same cable of metallic pairs, not coordinated and not synchronized with one another.

Abstract: The invention relates to an original method of frequency access multiplexing on networks with metallic pairs and a system of electronic apparatuses of reference that can cooperate with one another to implement this method. The method for access multiplexing on networks with metallic pairs comprises the steps of: - dividing ultra-broadband transmission frequencies into a hierarchical structure organised in bands, the last level of which comprises spectral resources obtained by applying a dual fairness criterion; - reserving said spectral resources obtained by the aforesaid division into a hierarchical structure for separate operators; - applying interference suppression techniques to said spectral resources.
