#0005 [TX/RX] Initial identification (T0/T1) time-over
The tone/pulse setting is wrong.
Make the correct tone/pulse setting.
The time it takes to connect to the other party’s line is too long.
(1) When registering an auto-dial number, put a relatively long pause after the tele-
phone number to delay the T0 timer start mechanism.
(2) In service mode, increase the T0 timer length using ‘10’ of #3 Numeric param.
so that a time-cover condition will not occur. (for transmission)
(3) In service mode, increase the T1 timer length using ‘11’ of #3 Numeric param.
so that a time-over condition will not occur. (for reception)
The other party does not respond.
Contact the operator of the other party, and find out the cause.
The other party’s communication mode (G2, G3, etc.) does not match.
The communication mode depends on each specific model, and no remedy can be
offered.
During transmission, the other party malfunctioned because of an echo.
(1) Provide echo remedy 1.
(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-dial number.
(4) Ask the operator of the other party to provide echo remedy 2.
(5) Ask the operator of the other party to decrease the transmission level.
During reception, the machine malfunctioned because of an echo.
