3.10.3.13.4. Usage Guidelines
A system-wide loss plan must be implemented using both the input gain and output
attenuation 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 is typically a minimum attenuation of –6
dB between phones, especially if echo cancellers are present. Connections are implemented to
provide 0 dB of attenuation when the input gain and output attenuation 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 attenuation.
