without audio dropout.
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.
