Title
Gain to IP
Shanghai New Rock Technologies Inc.
Set the voice volume gain towarding PSTN side, the default is -3. Taking
decibel as the unit, setting range is -6 ~ +9 decibels.
Set the parameter of FXO line impedance, with the default of 600 ohm.
The optional settings as below:
Complex
600（ohm）
900（ohm）
The time interval between FXO going off-hook and starting outpulsing
the first digit to PSTN. The default is 400 in milliseconds.
Set the timeout of calling DTMF on FXO port for inbound calls, ranging
from 10-60 seconds, with default of 24 seconds.
Select according to the characteristics of field lines. Before ringing A,
after ringing A, before ringing B, after ringing B. Note: A and B here
refer to two detection means provided within the equipment.
OMs will regard the busy tone signal with the repeat times specified here
as a valid hang-up signal. Default is 2, effective range is 2 ~ 50.
Set duration of busy tone signal, the default is 350 in milliseconds.
Set the interval time of busy tone, the default is 350 in milliseconds.
Explanation
Set the voice volume gain towarding IP side, the default is 0. Taking
decibel as the unit, setting range is -3 ~ +3 decibels. -3 means declining
of 3 decibels; +3 denotes the amplification of 3 decibels.
