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.
