3.10.3.15.4. Usage Guidelines
A system-wide loss plan must be implemented using both the input gain and output gain
commands. You must consider other equipment (including PBXs) in the system when creating
a loss plan. The default value for this command assumes that a standard transmission loss plan
is in effect, meaning that there must be an attenuation of –6 dB 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 dB. You cannot increase the gain of a
signal to the public switched telephone network (PSTN), but you can decrease it. If the voice
level is too high, you can decrease the volume by either decreasing the input gain or increasing
the output gain.
