(0,1) - The machine will disconnect the line without
sending a fax message, if the last 8 digits of the
received CSI do not match the last 8 digits of the
dialed telephone number. This does not work
when manually dialed.
(1,0) - The same as above, except that only the
last 4 digits are compared.
(1,1) - The machine will disconnect the line without
sending a fax message, if the other end does not
identify itself with an RTI or CSI.
(0,0) - Nothing is checked; transmission will
always go ahead.
This function does not work when dialing
is done from the external telephone.
Do not change the setting.
The setting determined by these bits is informed to
the transmitting terminal in the pre-message
protocol exchange (in the DIS/NSF frames).
COMMENTS
If there are more consecutive error lines in the
received page than the threshold, the machine will
send a negative response. The Low and High
threshold values depend on the sub-scan
resolution, and are as follows.
