Use it to set conditions for RTN signal transmission. If an error occurs often when the RTN signal is transmitted at
time of reception, increase the parameters to loosen the RTN signal transmission conditions.
MEMO:
The following error codes are associated with the transmission of the RTN signal at time of reception:
##104, ##107, ##114, ##201
The RTN signal transmission condition (1) is the ratio of the number of error lines in relation to the total number of
lines per page of reception images.
The RTN signal transmission condition (2) is the reference value*2 for burst errors*1.
The RTN signal transmission condition (3) is the number of errors not reaching the reference value for burst errors.
*1: transmission errors spanning several lines.
*2: If set to '15' a transmission error spanning 5 consecutive lines is identified as a burst error.
If any of these conditions is detected while an image signal is being revised, the RTN signal will be transmitted after
receiving the procedure signal from the transmitting machine. A higher parameter will make the transmission of the
RTN signal more difficult.

Use it to set the length of item (pause) automatically put between the access code an the ID code when a number is
dialed on an NCC (new common carrier) line.
[No. 06]
Use it to set the length of time (pause) automatically put between the ID code and the telephone number of the other
party when a number is dialed on an NCC (new common carrier) line.
