Polarity-Inverse - AddPac VoiceFinder AP200 User Manual

VoiceFinder AP200 VoIP Residential Gateway (RGW) User's Guide Version 1.1
This default value for this command assumes that a standard transmission loss
plan is in effect, meaning that normally, there must be -6 dB attenuation
between phones.
Connections are implemented to provide -6 dB of attenuation when the input
gain and output gain commands are configured with the default value of 0.
You can't increase the gain of a signal going out into the PSTN, but you can
decrease it. Therefore, if the voice level is too high, you can decrease the
volume by either decreasing the input gain value or by increasing the output
attenuation.
5.7.3.8.5. Examples
The following example on the router configures a 6-decibel gain to be inserted
at the transmit side of the interface:
port 1/4
output gain 3
