Setting the Output Gain
The output gain specifies, in decibels, the amount of gain from the VG248 to the
analog phone.
The country option you set on the VG248 determines the default output gain.
However, you might need to modify it to account for different cable lengths
(longer cables might require more gain), to make the signal louder or quieter, or
to use a phone from a different country.
Follow these steps to modify the input gain. The default setting is based on the
country code you set (see the
“Identifying the Country Code for VG248” section
on page 3-6
).
