Switching time between CED – DIS *4:
When the CED signal at 2100 Hz is sent out during reception of overseas communication,
the echo suppression stops so that the line condition becomes inferior with much echo.
As the countermeasure against the trouble, an interval is inserted after the echo
suppressor is re-started (echo suppressor re-starts after muting of 0.5 seconds) before
sending out the DIS signal upon \completion of the CED signal send-out by creating a
muted period of time. The international telephone line uses the four-wire system in which
signals are sent to the destination machine via the two-wire system –> four-wire system –
> two-wire system. The international telephone switchboard is equipped with the echo
prevention system (special switch circuit that prevents echo) called echo suppressor.
When it detects the tone signal of 2100 Hz, operation of the echo suppressor is stopped
temporarily.
Modem Transmission Speed

Sets the initial value of the modem transmission speed during fax send. This setting is
effective during all communications of direct dialing and Abbr. dialing. Communication
at 14.4 kbps (V.17) is performed when the menus [Admin Setup] – [User Install] –
[Super G3] is set to OFF and this setting is set to "33.6 kbps", "28.8 kbps". When this
setting is "14.4 kbps (V.17)", "9.6 kbps (V.29)", "4.8 kbps (V.27ter)", communication
with this setting is performed regardless of the "Super G3" setting.
