The number allowed for retransmission of the procedure signal
was exceeded during transmission
The transmission level is too low, and the other party cannot receive NSS, TSI,
DCS, TCF, or the training signal correctly.
Increase the transmission level so that the other party may receive the signal cor-
rectly.
After transmission of TCF immediately before the image signal, the other party
malfunctioned because of an echo.
1. Ask the operator of the other party to provide echo remedy 2
2. Using a manual call, press the Start button after hearing the 1st DIS from the
other party.
3. To prevent response to the 1st DIS from the other party, put a relatively long
pause to the telephone number when registering an auto-dialing number.
After transmission of the Q signal following the image signal, the line condition
became poor so that the other party cannot receive the image signal or the Q sig-
nal correctly.
1. Increase the transmission level so that the other party may service the image
signal or the Q signal correctly.
2. Decrease the transmission start speed.
3. Adjust the NL equalizer so that the other party may receive the image signal or
the Q signal correctly.
4. Add an echo protect tone to the V.29 modem signal for transmission.
