Configuration of bandwidth usage
It is possible to configure the maximum bandwidth used in the network by the Intercom Server.

In the drop-down list
Bandwidth in kBit
, select the bandwidth, which is used in the network by the
G8-NET card for data and speech.
In the drop-down list
Data-Bandwidth in kBit
, select the bandwidth, which is used for data packets
that leave the G8-NET cards.
At bad Internet connection or missing QoS
When transmitting speech via a data network, the Intercom Server performs a automatic jitter ad-
justment. At a bad Internet connection or missing QoS mechanisms, this can lead to a reduced
speech quality.
If the speech transmission at the start of conversations is faulty, the time in the drop-down list
Jitter
Buffer Start Delay
should be increased.
If speech quality is not good during conversations, the checkbox
No decrement of Jitter Buffer
should be activated. This prevents automatic readjusting of the jitter adjustment.
NOTE: Bandwidth
The overall bandwidth has always to be set higher as the data bandwidth. It is recommended to
select “unlimited”.
NOTE: Bandwidth
When the bandwidth is reduced, the packets leave the cards with a longer delay between them
(traffic shaping algorithm according to leaky bucket principle). This prevents a “packet burst”, which
can lead to a queue overflow at the router.
