-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.

Transmitter

Signal name			Abbreviation		Function			Remarks
	S signal			S	Short training			is a signal made as the
							S
						result of phase transition of S.
		signal
	S			S
PP signal			PP		Used by the modem of the
					receiver to train the equalizer.
TRN signal			TRN		Used by the receiver to deter-
					mine the transmission rate.

-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.

Transmitter/receiver

Signal name	Abbreviation	Function	Remarks
PPh signal	PPh	Used by the modem of the
		other side to train the equal-
		izer.
ALT signal	ALT	-
Modulation parameter	MPh	Informs the parameters used
		for the image transmission
		such as maximum data signal
		rate and type of the trellis cod-
		ing/pre-coding.
E sequence	E	-	20 bit sequence of “1”s in
			binary
