Multi user DSL method for the statistical multiplexing of copper access lines, characterized in that, for the downstream DS communication link, it comprises the steps of: - receiving units of information, UI, directed at transceiver devices of end users, on connects coming from a central office, through DSLAM equipment; - identifying groups of transceiver devices of end users where each group consists of a set of N copper lines connected to a same distributor of an access network node, starting from identifiers ID of said devices and said distributor, via said DSLAM equipment; - selecting and transmitting units of information, UI, on any one of the N copper lines belonging to the group, according to scheduling algorithms that take into account of at least the occupancy status of the lines of said group, via said DSLAM equipment; - receiving, demodulating and reconstructing units of information, UI, sent by said DSLAM equipment on the selected line, via an electronic device in said distributor of said access network node; - on the basis of the identifier ID in the received units of information, UI, sending said units of information, UI, on the selected copper line that uniquely connects said distributor to the destination devices, via said electronic device; - transmitting the units of information, UI, received to the destination devices, using the specific DSL technology provided for said devices, via said electronic device, and in that, for the upstream US communication direction, it comprises the steps of: - receiving and demodulating units of information, UI, directed by transceiver devices of end users to said distributor, on copper lines that uniquely connect devices to said distributor and using the specific DSL technology provided for said devices, via said electronic device; - sending the units of information, UI, received to the DSLAM equipment, using any one of the N copper lines belonging to the group and attested to the distributor, according to a scheduling algorithm that takes into account of at least the occupancy status of line buffers associated with said N lines, via said electronic device; - receiving and demodulating units of information, UI, on any one of the N copper lines of the group, via said DSLAM equipment; - transmitting the units of information, UI, received toward the central office, via said DSLAM equipment. - receiving units of information, UI, directed at transceiver devices of end users, on connects coming from a central office, through DSLAM equipment; - identifying groups of transceiver devices of end users where each group consists of a set of N copper lines connected to a same distributor of an access network node, starting from identifiers ID of said devices and said distributor, via said DSLAM equipment; - selecting and transmitting units of information, UI, on any one of the N copper lines belonging to the group, according to scheduling algorithms that take into account of at least the occupancy status of the lines of said group, via said DSLAM equipment; - receiving, demodulating and reconstructing units of information, UI, sent by said DSLAM equipment on the selected line, via an electronic device in said distributor of said access network node; - on the basis of the identifier ID in the received units of information, UI, sending said units of information, UI, on the selected copper line that uniquely connects said distributor to the destination devices, via said electronic device; - transmitting the units of information, UI, received to the destination devices, using the specific DSL technology provided for said devices, via said electronic device, and in that, for the upstream US communication direction, it comprises the steps of: devices, using the specific DSL technology provided for said devices, via said electronic device, and in that, for the upstream US communication direction, it comprises the steps of: - receiving and demodulating units of information, UI, directed by transceiver devices of end users to said distributor, on copper lines that uniquely connect devices to said distributor and using the specific DSL technology provided for said devices, via said electronic device; - sending the units of information, UI, received to the DSLAM equipment, using any one of the N copper lines belonging to the group and attested to the distributor, according to a scheduling algorithm that takes into account of at least the occupancy status of line buffers associated with said N lines, via said electronic device; - receiving and demodulating units of information, UI, on any one of the N copper lines of the group, via said DSLAM equipment; - transmitting the units of information, UI, received toward the central office, via said DSLAM equipment.
