Abstract

A method includes maintaining temporally parallel DSL data communication sessions with DSL modems of a group via a set of lines. The method includes, in response to substantially stopping to receive DSL communications from one of the DSL modems via one of the lines, transmitting a substantially reduced average power to the one of the lines and monitoring the one of the lines to determine whether DSL communications have restarted being received 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 DSL communications have restarted being received from the one of the DSL modems.
