2 to transfer data using the dynamic link selection which allows the MultiMux to
select the least busy link.
Voice/Fax Channel The Voice/Fax Channel Digitizing Rate command selects from
Digitizing Rate two digitized or compressed rates 9600 or 16000 bps. At the
16000 bps rate, the voice transmission will be clearer. The
V(1/2)DR V1DR9600 places voice/fax channel 1 at a digitized or compressed rate of 9.6K bps. Note,
with silence suppression enabled, less than 9600 bps of the link is used. The default digitizing rate is
16000 bps.
Voice/Fax Channel The Voice/Fax Channel Input Level Gain command selects the
Input Level Gain gain of the input voice/fax signal. As the input level gain is increased, the volume level
increases. The input level gain V(1/2)IL ranges from -6 to 18db in increments of 1db with 0 db producing
no gain.

When the input level on the local mux is adjusted, the volume level heard on the
remote mux will change accordingly. The input level gain needs to be set on the transmitting mux (talking).
This will increase the volume that the person at the receiving mux hears. To
increase the input level gain at the receiving mux will have no affect on what this person hears.

Note
For the best results, increase or decrease both the
local output level and remote input level settings
by a small amount to change the volume level
heard at the local voice/fax channel.
The default settings per configuration are as follows:
Local Remote

Voice/Fax Channel The Voice/Fax Channel Output Level Attentuation command
Output Level Atten. selects the output signal level properties of the voice/fax transmission. As the
output level attentuation increases, the V(1/2)OL volume level decreases. The signal level properties are
incremented in decible levels of 0.75db. Command V(1/2)OL0 is no signal level
attentuation for the 2-wire and 10db for the 4-wire.
