The transmitting machine cannot use fall-back
The line condition is poor, and the signal from the other party cannot be received
correctly even at 2400 bps.
1. Ask the operator of the other party to increase the transmission level so that the
signal may be received correctly.
2. Adjust the NL equalizer so that the signal may be received correctly.
3. Loosen the RTN transmission conditions so that RTN will not be transmitted.
The machine malfunctioned because of an echo.
1. Provide echo remedy 1.
2. Decrease the transmission level so that an echo of the transmitted signal will
not be received.
