Communication

Signal sending level

Set the level adjustment for sending signals from the modem. Setting can be 
made over the range of 0 to 26 in 1dBm increments by binary inputting.
Since the maximum level differs according to country, if a value above the 
maximum level is set, the maximum value for the present country code will be 
adopted. (For North America and China, there is no limitation on the max. send 
level.)
When set to a value greater than the upper limit, it is considered as setting to 
the upper limit. When set to a value smaller than the lower limit, it is considered 
as setting to the lower limit.
If, however, it is set to 27 to 255, it is considered as setting to 26.

Transmission

Setting of call time (T0 
timer setting) in 
automatic transmission

Setting to determine how many seconds to call when the other party doesn’t 
respond at times of automatic transmission.
Setting can be made over the range of 30 to 60 (China: 30 to 45, Russia: 30 to 
35) seconds in 15 (Russia: 5) second increments by binary inputting N ((15 
(Russia: 5) seconds x N) + 30 seconds).
The initial value is reverted to if a value outside of the setting range is set.

Timer

4-7

Communication

T1 timer setting

Setting to determine how many seconds the line is connected when the other 
party’s machine doesn’t respond to FAX communication.
Setting can be made over the range of 30 to 105 seconds in 5-second 
increments by binary inputting ((5 seconds x N) + 30 seconds).
T1 timer is the timer used from the point where the other party’s machine 
recognizes (CED or DCS) as FAX following line connection. 35±5 seconds 
according to the ITU-T standard.

Timer

Communication

Si3056 SiDAA Reg.31 
FILT

Setting to determine whether the signal of the following signal frequency band 
or less should be reduced or not.
This setting is available when there is the noise on the signal frequency band of 
300Hz or less. If there is the noise on the signal frequency band of 300Hz or 
less, the phenomenon that cannot receive FAX signal from the other side of the 
machine at all will happen.
“0”: Reduce the signal of 5Hz or less
“1”: Reduce the signal of 200Hz or less

Communication

T2 timer setting

The time until a command is received is set.
"00": 6 seconds
"01": 7 seconds
"10": 8 seconds
"11": 9 seconds
This is the timer for receiving a command such as the DIS signal. 6

1 seconds 

in the ITU-T standards. 

3, 4

Communication

T4 timer setting 
Timer during automatic 
operation (+1.5 
seconds at times of 
manual operation)

This sets the timer for up until reception of the response.
+1.5 seconds at times of manual operation
"00": 3 seconds
"01": 4 seconds
"10": 5 seconds
"11": 6 seconds
This is the timer for up until reception of the response to the DCS signal, etc. 3 
seconds ±15% under the ITU-T standard.

Timer

Reception

EOL detection timer

Setting to determine how many seconds to set the detection timer for EOL 
(EndOfLine) during Phase-C reception in G3.
"0": Setting to 13 seconds
"1": Setting to 25 seconds
When error occurs in EOL detection, treat as non-detection of EOL.

Timer

Communication

Sharp machine mode

Setting is made whether Sharp's unique procedures (relay, confidential) are 
allowed or not by not sending NSF/NSS/NSC and not confirming that the 
machine is a Sharp machine or not.
"0": Check
"1": Not check

7, 8

Communication

Modem lightning 
protection measures

Function that corresponds to IEC lightning surge requirements as prescribed in 
the European CE standard.
In cases where the machine cannot shift from CFR or MCF to high-speed 
signals (image signals) due to lightning interference, this extends the MPS 
waiting time.
"00": 0 second
"01": 20 seconds
"10": 30 seconds
"11": 40 seconds
