b-3)
Equalizer and echo canceller training (Phase 3)
To optimize the filters such as an equalizer, the training (adjustment) is performed
according to the parameters set in phase 2.

Transmitter
b-4)
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.

Meaning
Short training
The modem of receiver uses it for
training the equalizer.
It is used for determining the trans-
mission rate by the receiver.
Remark
S is a signal that makes a
transition from phase S.
