Out_wait – Enter the time in milliseconds that the FXO port keeps waiting after
seizing a telephony port and before dialing out DTMF signals. The de fault value is
1000 millisecond.
Bat_vol – Before seizing a FXO port for dialing out, the F XO port detects voltage
level on the port to ensure that the port is connected an d available. If the voltage
level is below this threshold level, the port is declared unavailable
Call Progress
This screen is for configuring the CP (Call Progress) tone detection for FXO port. For
normal application, it is not recommended to modify the default se ttings.
Tone Detection – This specifies the ON/OFF of CP tone (busy tone for general
case) cadence periods. For instance, On of Tone 1 is 500 and Off of Tone 1 is 500
means the cadence is ON for 500ms then OFF for 500ms. If more than one ON/OFF
cadence detections are required, for example, ON 300ms/OFF 40 0ms, then ON
500ms/OFF 600ms, then program On of Tone 1 to be 300, Off of Tone 1 to be 400,
On of Tone 2 to be 500, Off of Tone 2 to be 600.
Repeat Count – Input the minimum detection cycles for the above CP tone cadence.
Tone On Fraction – Input the CP tone sensitivity level. This parameter controls the
SNR and frequency offset. The default value is 50%.
