Tone for Echo
TX (During Transmission)
When set to Enable
• DIS ignore once *1:
• EP tone addition during V29 send *2:
• Wait time between DIS – DCS *3:
When set to Disable
• DIS ignore once *1:
• EP tone addition during V29 send *2:
• Wait time between DIS – DCS *3:
This setting is effective during all communications of direct dialing and Abbr. dialing.
DIS ignore once *1:
During the overseas communication, the DIS signal can be ignored once in order to re-
start the echo suppressor function that has been stopped by the CED signal. The MFP
responds against the second DIS signal and sends out the DCS signal. With this setting,
the MFP can send out the DCS signal under a good line condition with less echo. This
setting is used in the case when the communication error such as T.1.1 occurs due to
adverse effect of echo during the overseas communication.
EP tone addition during V29 send *2:
During the overseas send, reception of the training signal by the destination machine can
be ensured by adding the EP tone before the sending the training signal to avoid line
delay.
The EP tone of 0.5 seconds is added to the training signal of 9600/7200 bits/s +
TCF/training + image information.
The EP tone of 0.5 seconds at 1700 Hz can be destroyed by the group delay of
communication line so that the head portion of the training signal is damaged. In such a
case, reception of the training signal by the destination machine can be ensured by adding
the EP tone before sending the training signal.
Some types of fax machines cannot receive the training signal 9600/7200 bits/s +
Note!
TCF with the EP tone. You should be aware of this type of fax machine.
