dial tone
detection
0: Normal parameter
1: Specific parameter
0: This uses the fixed table in the ROM for dial tone detection.
1: This uses the specific parameter adjusted with SRAM (69ECBEH -
69ECDEH). Select this if the dial tone cannot be detected when the "Normal
parameter: 0" is selected.

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.
