[Bit 0]
Selects whether or not to monitor loop current. When 'Yes' is selected, if loop current cannot be detected before
dialing, or if the loop current is cut during or transmission, the line is released.
[Bit 1]
In automatic recieving, CI frequency check can be selected. If 'Yes'is selected, the upper and lower limits of the CI
frequency are checked, and automatic recieving can only go ahead if both values meet German regulations.
[Bit 2]
Use it to specify the number of last flag sequences for the procedure signal (300 bps). Select '2' if the other party fails
to receive the procedure signal transmitted by the machine normally.
MEMO:
The following error code are associated with transmission:
##100, ##280, ##281, ##750, ##753, ##754, ##755, ##758, ##759, ##760, ##763, ##764, ##765, ##768, ##769,
##770, ##773, ##775, ##778, ##780, ##783, ##785, ##788,
[Bit 3]
Use it to select reception to use after transmission of the CFR signal.
If an error occurs often because of the line condition at time of reception, set it to '1'and, at the same time, set 'ECM
RX' to 'OFF' for user data.
MEMO:
The following error codes are associated with the line condition at time of reception:
##107, ##114, ##201
Be sure to change bit 4 before changing this bit; resort to this bit only if an error still occurs.
When set to '1' only high-speed (image) signals will be received after the transmission of the CFR signal.
[Bit 4]
Use it to select the length of time during which low-speed signals are ignored after transmission of the CFR signal.
Select '1500 msec' if reception of image signals is not good because of a poor line condition.
