-Equalizer and echo canceller training (Phase 3)

Training (adjustment) is performed according to the parameters set in the phase 2 to optimize the filters such as an equalizer.

PP signal			PP			Used by the modem of the
						receiver to train the equalizer.

TRN signal			TRN			Used by the receiver to deter-

-Final training (Phase 4)

The settings such as the maximum value for the data rate, selection of the trellis encoder, and data rate which can be supported are made in this phase.
