Jitter is a measure of the quality of the network connection. It
represents the variation in the time period with which audio packets
are received. For example, if an audio packet is expected every 10
milliseconds, but one audio packet is received 13 milliseconds after
another, this represents a jitter of 3 milliseconds.
If the jitter gets too high the panel will start to experience audio
dropouts.
WAN mode panels can deal with larger jitter than LAN mode panels,
and Internet higher than WAN mode, as they use larger jitter buffers to
smooth out the uneven arrival of audio packets. However the downside
of this is that the larger the jitter buffer, the longer the audio delay.
• Average Jitter - the average packet interval in microseconds.
• Max Jitter - the highest packet interval measured in milliseconds.
LAN mode panels can cope with jitter up to 80 milliseconds
without audio dropout.
WAN mode panels can cope with jitter up to 120 milliseconds
