minimum and maximum values. An Optimization Factor adjustment controls how quickly the length of
the Jitter Buffer is increased when jitter increases on the network. The length of the jitter buffer
directly effects the voice delay between MVP110 gateways.
The default minimum dynamic jitter buffer of 150 milliseconds is the minimum delay that would be
acceptable over a low jitter network. The default maximum dynamic jitter buffer of 300 milliseconds is
the maximum delay tolerable over a high jitter network.
The Optimization 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.
The Optimization Factor can be configured in the range of 0 to 12 with a default setting of 7.

Regional tab

The Regional tab controls the voice communications for the country or region in which the MVP110 is
being used.
From the Country/Region list, you can select the country or region for which you are configuring the
MVP110. The Tone Pairs group always displays the tones used in the country or region currently
selected. In addition to Australia, Central America, Chile, Europe, France, Japan, UK, and USA, there
is a Custom selection (with defaults identical to USA) that will make the Custom button active.
Clicking the Custom button enables you to edit the Tone Pairs and establish custom sets of tone
pairs for Dial Tone, Ring, and Busy on a Custom Tone Pair Settings dialog box.
The Pulse Generation Ratio group contains two ratios: the 60/40 is for the USA, and the 67/33 ratio
is for international applications.
