Ring Frequency Min The lower limit of the ring frequency used to detect the ring
signal.
The default is 10.
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 90.
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 256
ms.
