FXO Port
Impedance
Desired impedance of the FXO Port. Choose from {600,
900, 370+620, 270+750||150nF, 220+820||120nF, 370
+ 620 || 310nf, 320 + 1050 || 230nf, 370 + 820 || 110 nf,
275 + 780 || 115nf, 120 + 820 || 110nf, 350 + 1000 ||
210nf, 0 + 900 || 130nf}
The default is 600.
The impedance values for various countries follows:

Ring Frequency Min The lower limit of the ring frequency used to detect the ring
signal.
The default is .
SPA To PSTN Gain dB of digital gain (or attenuation if negative) to be applied
to the signal sent from the SPA to the PSTN side. The range
is -15 to 12.
The default is 0.
Ring Frequency
Max
The higher limit of the ring frequency used to detect the
ring signal.
The default is .
PSTN To SPA Gain dB of digital gain (or attenuation if negative) to be applied
to the signal sent from the PSTN side to the SPA. The range
is -15 to 12.
The default is 0.
Ring Validation
Time
Specify the minimum signal duration required by the
Gateway for recognition as a ring signal. The default is
.
