NC-AD300E Manual- 32 -the action will be stopped. Recommended value: 2, fill in 0 to take the default value: 2.FxoWaitDialToneSeconds: When call out through analog trunk (FXO), you need to detect thedial tone in order to call out. If more than 5000 milliseconds have not yet detected dial tone, thenstop to detection; If this value is less than 2000 milliseconds, don’t do dial tone detection, line will becall out after the time value equal to FXOAutoAnswerDealyFXOAutoAnswerDealy: when call out FXO, if this value is 0, indicating only polarity reversalsignal is detected then connected, if it is (1 ~ 9), indicating a direct connect (not detect polarity reversal,nor delay.); if equal or greater than 10, then the delay specified milliseconds to automatically connect.For example, as here, fill in 6000, then delay 6000 milliseconds to connect.FXOAutoDetectedInterval, you can set a long time to detect FXO lines, 0 means not detected.FxsDialFirstKeyOver, if user pick up phone but no dial-up, after this vlue then the line will be busy.Set to 0 will always wait no busy.FxsDialNextKeyOver, if user pick up the phone and dial number, but more than this time no morebutton pressed, then device think the dial-up has been completed. Set to 0 will be always waiting andno time outWhen the FxsDialFirstKeyOver and FxsDialNextKeyOver are set to 0 at the same time, AD300Ewill not process and called number but directly route to the other side.After completion of editing, write to ROM and RAM can be effective immediately.5.2.5.3 Call Detection SettingsWhen the line type is FXO, you can specify whether you detect DTMF. If you do not detectDTMF caller, the default detection is FSK. In Index area select "Line Part" goes to "LineProperty"to see the table.When you need to determine the beginning and end of DTMF call signs, in the "analog line"parameter setting page as below:Flag can only be one of the symbols in the "ABCD * #".After completion of editing, write to ROM, restart the device to take effect.5.2.5.4 Line Volume Set
