0-1
Maximum allowable carrier drop during
image data reception
These bits set the acceptable modem carrier
drop time.
Try a longer setting if error code 0-22 is
frequent.
Bit 1 Bit 0 Value (ms)
0 0 200
0 1 400
1 0 800
1 1 Not used
2
Select cancellation of high-speed RX if
carrier signal lost while receiving
0: Off
1: On
This switch setting determines if high-speed
receiving ends if the carrier signal is lost when
receiving during non-ECM mode
3 Not used Do not change the settings
4
Maximum allowable frame interval during
image data reception.
0: 5 s 1: 13 s
This bit set the maximum interval between EOL
(end-of-line) signals and the maximum interval
between ECM frames from the other end.
Try using a longer setting if error code 0-21 is
frequent.
5 Not used Do not change the settings.
6
Reconstruction time for the first line in
receive mode
0: 6 s 1: 12 s
When the sending terminal is controlled by a
computer, there may be a delay in receiving
page data after the local machine accepts set-
up data and sends CFR. This is outside the T.30
recommendation. But, if this delay occurs, set
this bit to 1 to give the sending machine more
time to send data.
Refer to error code 0-20.
ITU-T T.30 recommendation: The first line
should come within 5 s of CFR.
7 Not used Do not change the settings.
G3 Switch 0B Not used (do not change the settings).
