1. A method for synchronizing an initialization procedure with TTR in an ADSL Annex C communication system having a transmitting node and a receiving node that are communicatively coupled, the method comprising:

  • transmitting a specially defined signal during one or more sets of known FEXT symbols of a first outgoing hyperframe, so that when detected at the receiving node, the specially defined signal establishes synchronization to TTR thereby enabling a synchronized initialization procedure, wherein the synchronized initialization procedure includes;

    receiving a first response signal during one or more sets of FEXT symbols of a first incoming hyperframe to confirm receiving node detection of the specially defined signal.
