As the countermeasure against the trouble, aninterval is inserted after the echo suppressor is re-started (echo suppressorre-starts after muting of 0.5 seconds) before sending out the DIS signal uponcompletion 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 aresent to the destination machine via the two-wire system –> four-wire system –> two-wire system. The international telephone switchboard is equipped with theecho prevention system (special switch circuit that prevents echo) called echosuppressor. When it detects the tone signal of 2100 Hz, operation of the echosuppressor is stopped temporarily.5.8.3 H/Modem Rate5.8.3.1 TX(During send)Value Default Display condition33.6 Kbps28.8 Kbps14.4 Kbps9.6 Kbps4.8 Kbps33.6 Kbps NoneSets 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] – [UserInstall] – [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)”, communicationwith this setting is performed regardless of the “Super G3” setting.5.8.3.2 RX(During receive)Value Default Display condition33.6 Kbps28.8 Kbps14.4 Kbps9.6 Kbps4.8 Kbps33.6 Kbps NoneSets the initial value of the modem transmission speed during fax receive.Communication at 14.4 kbps (V.17) is performed when the menus [Admin Setup] – [UserInstall] – [Super G3] is set to OFF and this setting is set to “33.6 kbps”, “28.8 kbps”.
