o LAN mode panels can cope with jitter up to 80 milliseconds without audio
dropout.
o WAN mode panels can cope with jitter up to 120 milliseconds without audio
dropout.
o Internet mode panels can cope with jitter up to 200 milliseconds without
audio dropout.
• Forward Error Correction - this allows the IVC-32 to recover from corruption in
audio packets caused by a poor network link, at the cost of slightly increased
network traffic and slightly higher audio delay. Forward Error Correction is set to a
HIGH level in internet mode, LOW level in WAN mode and is disabled in LAN
mode.
• Silence Suppression - this reduces the network traffic generated by a panel by
stopping the transmission of packets when there is no audio input (that is, the
microphone is turned off). It can cause a slight increase in audio delay. Silence
suppression is enabled in WAN and Internet mode, but disabled in LAN mode.
• Rx Packets - this displays a count of the IP packets that a panel has received,
and can be used to check the network connection. When Silence Suppression is
enabled the numbers may only increase when the panel microphone is enabled.
• Tx Packets - this display a count of the IP packets that a panel has sent, and can
be used to check the network connection. When Silence Suppression is enabled
the numbers may only increase when the panel microphone is enabled.
• Rx Drops - The number of audio packets that have been lost. This can be due to
network quality.
