A method is described for reducing interferences in communications exchanged along a plurality of communication channels operated by a first operator, caused by one or more alien communication channels operated by a second operator. The method comprises the steps of: (i) providing the second operator with information that relates to interferences experienced at the plurality of communication channels operated by a first operator, due to traffic conveyed along alien communication channels operated by the second operator; (ii) modifying the original signals conveyed by the second operator along the alien communication channels; (iii) sending the modified signals to the first operator; and (iv) applying the modified signals by the first operator to reduce interferences in communications exchanged along the plurality of communication channels and operated by the first operator.

Method and device for secured sharing of signals for crosstalk cancellation

A method and device are provided for affecting data conveyance within a cable comprising a plurality of copper wire lines. The method comprises: providing information about crosstalk interference experienced by the copper wire lines; for each copper wire line experiencing crosstalk interference (interfered line), identifying which other copper wire lines induce crosstalk interference to that interfered line; partitioning the copper wire lines into interference groups, where each interference group comprises at least one copper wire line, wherein at least one of the interference groups comprises at least three copper wire lines, and wherein in case that a given interference group comprises more than two copper wire lines, then each of the copper wire lines belonging to that interference group is subjected to interference induced by another copper wire line that belongs to that interference group; and based on the partitioning step, changing operational settings of at least one copper wire line.

Method for managing data transport using crosstalk data

A method is provided for initiating communications over a channel between a transmitter and a receiver within a specified spectral range, subject to a mask to be applied at the transmitter so as to attenuate at least one segment of the spectral range. The method includes providing to the receiver a definition of the at least one segment and of a level of attenuation to be applied within the at least one segment during a training interval of the communications. A training signal is transmitted from the transmitter to the receiver while applying to the training signal the level of attenuation within the at least one segment. The receiver compensates for a response of the channel based on the received training signal and on the definition of the at least one segment and of the level of attenuation.

Communication start-up with variant spectral density mask

A method for communicating at least one of the hook state and associated in line filter indication from the ADSL Transceiver Unit-Remote Side to the ADSL Transceiver Unit-Central Office, or vice versa, for improving the performance of splitterless ADSL systems. This information is used to determine robust bits and gain allocation during startup, and to correct the profile selection during fast retrain.
