# Fax Parameter List Optional Channels 2 and 3 (CH2, CH3)

400

401

402

Set the lower limit value / upper limit value of the ringing signal detection frequency.
When connecting line = PSTN, detection is performed in the range of 12 to 66Hz by default.

11 - 21

Set the lower limit value / upper limit value of the ringing signal detection frequency.
When connecting line = PBX, detection is performed in the range of 11 to 80Hz by default.

Minimum time to recognize call signal ON
If it is shorter than this time, it does not judge it as a call signal and does not answer incoming call. (A calling tone rings with ON of 80ms. )

Maximum time to recognize call signal ON
If it is longer than this time, it does not judge it as a call signal and does not answer incoming call. A calling tone rings. )

Call signal off confirmation time
When the calling signal OFF time longer than this setting is detected, the calling signal is counted as 1 time.
It does not count when the OFF TIME is shorter. Reference value for connection line PSTN.

If the off time is longer than this, it is judged that the call signal has disappeared.
Resets IR counter. Display of during calling disappears. )

Call signal off confirmation time
When a IR OFF TIME longer than the set value is detected, counts one IR.  It does not count when the OFF TIME is shorter.
Line type = the reference value for PBX

Dial type

Tone/10PPS/20PPS

Used to register a fax number in the address book. Changing the pause waiting time to enter with the pause button.

This function changes when the response of the partner fax is slow and exceeds the response waiting time.
It is the same effect as putting a pose with a pause button after dialing.

Adjusts Send time/Inter-digit time for sending DTMF (Tone). Dial speed can be increased by decreasing set value.
Note that if it is set too fast, failures in dial tone detection or connection may occur.
70-70ms or longer is recommended.
Make sure to perform dial check test after the change to confirm the connection.

On/Off

If there is no problem with the telephone line and the connection of the telephone line, but the error of “Automatic line check function” causes “line not connected” or “line reverse insertion” error, set to Off.

In the initial setting, if the dial tone is detected for 1000 ms, it is judged that there is a dial tone.
* Dial tone detection waiting time is fixed at 10s.

Dial tone off ignore time (PSTN)

The dial tone off time of this set value is regarded as the dial tone continuation.
Connection line = PSTN

Dial tone off ignore time (PBX)

The dial tone off time of this set value is regarded as the dial tone continuation.
Connection line = PBX

Pause before dial when no dial tone is detected

If dial tone detection = off, pause at this setting before dialing.

Duration time of Busy tone detect on [Min]

Minimum time to recognize busy tone signal on.
Shorter than this time does not judge it to be a busy tone.

Busy tone detection on duration [maximum]

Maximum time to recognize busy tone signal on.
Longer than this time does not judge it as a busy tone.

Busy tone detection off duration [minimum]

Busy tone signal off confirmation time.
Upon detecting the busy tone signal off time longer than this setting, the number of busy tone signals is counted as one. It does not count when the OFF TIME is shorter.

Busy tone detection off duration [maximum]

If the off time is longer than this, it is determined that the busy tone signal has disappeared.
(Busy tone signal count is reset)

Normal/Long

Level of judgment of line training.
When set to Long, performs the training of line condition harder.  (It becomes easy to feed back)

75 ms/1 sec

Set the signal interval time between the CED signal and the DIS signal selected at incoming call.
change this to 1s to disable the echo suppressor when communicating with overseas.

V.29 Tone for echo suppressor

On/Off

Adds an EP TONE when sending V29 9600/7200bps.
Used when a communication error has occurred due to a line echo in overseas communication.

Transmission start method (ignoring the first DIS)

Ignore the first DIS at the time of transmission and receive from the second DIS.
Used when a communication error has occurred in overseas communication due to the effect of a repeat echo or the like.

Select "EOL x 6" or "EOL x 12" of RTC signal for termination of PIX signal (switch from high speed to low speed).

Until Detect Always

Until Detect: The monitor turns on when making a call and turns off when a fax signal is detected.
Always: The monitor is always on. You can listen to the fax communication signal from the monitor speaker, so you can use it when investigating problems such as line failures.
* Don't forget to return to the original state after confirming the trouble.

V.27ter
V.17
V.29
V.34

Linking with communication mode of fax setting
ECM is required for V.34.

MH
MR
MMR

On/Off

Interlocked with “error correction mode (ECM)” in fax settings.
If ECM is turned off, V.34/MMR/Color communication are disabled.

100 ms
200 ms
500 ms

Procedure Adjust signal time between signals.
Used when an error occurs during communication procedure due to line echo/delay etc.
