Bit Switches
SM 121 D393
Fax Option
Type C5000
(D393)
0-1
Maximum allowable carrier
drop during image data
reception
Bit 1: 0, Bit 0: 0 = 200 (ms)
Bit 1: 0, Bit 0: 1 = 400 (ms)
Bit 1: 1, Bit 0: 0 = 800 (ms)
Bit 1: 1, Bit 0: 1 = Not used
These bits set the acceptable modem carrier drop
time.
Try using a longer setting if error code 0-22 is
frequent.
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.
G3-2 Switch 0B - Not used (do not change the settings.)
