ABSTRACT:
This invention improves the success rate of rereception of a primary channel equalizer training signal, which is performed when, in a data communication apparatus having an ITU-T recommendation V.34 communication function, a control circuit performs control to receive a line probing signal, and thereafter, shift to reception of a primary channel equalizer training signal, and to control circuit performs control to, when the primary channel equalizer training signal is not detected within a predetermined time, send a tone A signal and receive a tone B signal, and thereafter, shift to transmission of a limited INFOh signal.
