1. A method, comprising:

  • transiting a first DSL transceiver from a DSL communication session to a DSL wait state in which the first DSL transceiver transmits substantially lower power to a local-end line in response to an interruption or a substantial stop in the DSL communication session of DSL communications in one direction between the first DSL transceiver and a second DSL transceiver;

    transmitting a first DSL acknowledge signal from the first DSL transceiver to the local-end line in response to receiving a DSL wait signal at the first DSL transceiver from the local-end line; and

    in response to the transmitting, resuming to transmit DSL communications from the first DSL transceiver to the local-end line at a power substantially higher than a power transmitted to the local-end line in the DSL wait state, the act of resuming being responsive either to receiving at the first DSL transceiver a substantially higher DSL power than a DSL power received thereat in the DSL wait state or to receiving at the first DSL transceiver a second DSL acknowledge signal from the second DSL transceiver.
