The output level attentuation needs to be set at the DataTalker that is receiving (hearing).
Increasing the output level gain at the transmitting DataTalker will have no affect on the loudness
heard by the person at the receiving DataTalker:

Note: For the best results, increase or decrease both the local output level (OL) and remote input
level (IL) settings by a small amount to change the volume level heard at the local voice/fax
channel.
The default settings are as follows:
Configuration Local Remote
IL OL IL OL
FXS to FXO 4 0 6 1
FXS to FXS 3 12 3 12
E&M to E&M (4-wire) 3 4 3 4
The Input Level Gain option selects the gain of the input voice/fax signal for voice/fax channel.
As the input level gain increases, the volume level increases. The input level gain ranges from 0
to 24 in increments of 1db with 0db producing no gain. Two digits have to be entered.
When the input level on the local DataTalker is adjusted, the volume level heard on the remote
DataTalker will change accordingly. The input level gain needs to be set on the transmitting
DataTalker (talking). This will increase the volume that the person at the receiving DataTalker
hears. To increase the input level gain at the receiving DataTalker will have no affect on what this
person hears.

The Silence Suppression option keeps moments of silence from using up bandwidth on the
composite link. The options are Off, Medium, and Maximum. Typically, a voice conversation is 50
to 60% silence. Silence suppression is helpful when using a slow composite link speed such as
19.2K bps. When silence suppression is off, all sound passes through the link, even silence.
Silence suppression is active when there is no activity on the voice/fax channel. The maximum
setting increases the volume necessary for sound to be sent over the link.
