Use it to specify RTN signal transmission conditions. If an error tends to occur often as a result of
transmitting an RTN signal at time of reception, increase the parameters to relax the RTN signal
transmission conditions.
Memo
The following errors may occur as a result of transmitting an RTN signal at time of reception:
##104, ##107, ##114, ##201.
The RTN signal transmission condition (1) represents the ratio of error lines to total lines on a
single received page.
The RTN signal transmission condition (2) represents the reference value** for a burst error*.
The RTN signal transmission condition (3) represents the number of errors (falling short of the
burst error standard value).
*Transmission error continuing over several lines.
**If '15' is set, for instance, a transmission error continuing over 15 lines will be identified as a
burst error.
If any of the conditions is detected while receiving image data, the device will send an RTN
signal after it has received a procedure signal of the transmitting device. Increasing these
parameters will accordingly hinder transmission of the RTN signal.
No. 05
Use it to set the length of the pause which will automatically be inserted between an access code and
an ID code when a number is dialed using the NCC (New Common Carrier) line.
No. 06
Use it to set the length of the pause which will automatically be inserted between an ID code and the
telephone number of the callee.
No. 09
Use it to set the number of digits for comparison between the TSI of the other device and the
appropriate telephone number registered under the one-touch dial or speed dial directory (when
restrictions are imposed on destination telephone numbers in relation to the direct mail prevention
function or the memory box function).
Be sure to change, if necessary, this parameter before registering telephone numbers.
No. 10
Use it to set the time length for line connection identification. Raise the parameter if an error tends to
occur often because of line condition.
Memo
The following errors may occur because of line condition: ##005, ##018.
The time length of connection identification is between the transmission of the dial signal and
the termination of the line for the transmitting device, while it is between the transmission of the
DIS signal and the termination of the line for the receiving device.
