Voice/Fax Parameter Definitions (cont’d)

Field Name	Values	Description
Dynamic	Jitter
Maximum	60 to 400	The maximum dynamic jitter buffer
Jitter Value	ms	of 400 milliseconds is the maximum
		delay tolerable over a high jitter
		network.
		Default = 300 msec
Optimizat-	0 to 12	The Optimization Factor
ion Factor		determines how quickly the length
		of the Dynamic Jitter Buffer is
		changed based on actual jitter
		encountered on the network.
		Selecting the minimum value of 0
		means low voice delay is desired,
		but increases the possibility of jitter-
		induced voice quality problems.
		Selecting the maximum value of 12
		means highest voice quality under
		jitter conditions is desired at the
		cost of increased voice delay.
		Default = 7.
