    Abstract: The present invention relates to an access node (200) with point-to-multi -point transmission capabilities. The access node comprises first transmit/receive circuitry (210m) with digital signal processing logic (DSP) and digital-to-analog/analog-to-digital conversion logic (DAC; ADC), and second transmit/receive circuitry (220n) with transmit/receive amplifiers (LD; LNA) and line adaptation units (LAU) for connection to a transmission line (Ln). The access node further comprises an analog switch (230) for dynamically connecting one of the first transmit/receive circuitry with one of the second transmit/receive circuitry according to a transmit/receive cross-connect table (XT), and transmit/receive control logic (240) for updating the transmit cross-connect table according to a transmit/receive traffic pattern over the respective transmission lines. The transmit/receive traffic pattern conforms to a Time-Division Multiple Access TDMA scheme, or is determined according to actual transmit/receive traffic demands. The transmit/receive control logic is further for individually disabling or enabling the transmit/receive amplifiers concomitantly with the updating of the cross-connect table.

    Abstract: The invention provides a method and system, preferably an access node, for cancelling crosstalk among one or more plurality of network links. Crosstalk from a second network link, a disturber line, is according to the method (substantially) cancelled in a first network link, the victim line. Thereto a suitable signal component is provided to a third network link, the cancellation line. The signal component generally cancels the crosstalk signal from the second network link by providing a signal substantially in anti-phase. The third network link could be a spare line.

    Abstract: A method includes maintaining temporally parallel DSL data communication sessions with DSL modems of a group via a set of lines. In response to a substantial stop to reception of DSL communications from one of the DSL modems via one of the lines, the method includes transmitting a substantially reduced average power to the one of the lines and monitoring the one of the lines to determine whether reception of DSL communications has restarted from the one of the DSL modems. The method also includes resuming the maintaining of the temporally parallel DSL communication sessions in response to the monitoring determining that the reception of DSL communications from the one of the DSL modems has restarted.

    Abstract: An apparatus includes a DSL transceiver configured to transit to a DSL wait state in which a power transmitted from the DSL transceiver to a local-end line is substantially reduced in response to an interruption or substantial stop at the DSL transceiver of reception of DSL communications from the local-end line. The DSL transceiver is configured to transmit to the local-end line a DSL acknowledge signal in response to receiving from the local-end line a DSL wait signal. The DSL transceiver is configured to resume to transmit DSL communications to the local-end line at a power substantially higher than the power transmitted thereto in the DSL wait state in response either to receiving from the local-end line DSL transmissions at a substantially higher power than received there from in the DSL wait state or to receiving from the local-end line a second DSL acknowledge signal.
