2.5.6 Setting QoS Parameters

The quality of service (QoS) settings determine the mode of processing IP data packets while
in a conference call.
Procedure
Step 1 Choose Settings > Network > IP > QoS, and then set the parameters listed in
Table 2-8 QoS parameters
Parameter
QoS type
IP priority
Service type
DSCP
Network jitter
Issue 09 (2012-09-03)
Description
Select either of the following:
l Priority: If this option is selected, set the IP priority and the service
type.
l DiffServ: If this option is selected, set the Differentiated Services
Code Point (DSCP).
This specifies the priority of data packets sent by the terminal and
forwarded by a network device. The value ranges from 0 to 7. The higher
the value, the higher the priority.
The network provides five types of service for the terminal to send and
receive data packets.
l Normal: The network devices transmit the data packets without
special processing.
l Minimum delay: The data packets are transmitted at the highest rate
with minimum delay.
l Maximum throughput: A large amount of data packets can be
transmitted on the network.
l Highest reliability: The data packets can be transmitted to the
remote site completely and correctly.
l Minimum cost: The data packets of equal traffics are transmitted at
the minimum cost.
This specifies the service level of data packets sent by the terminal
during transmission.
The value ranges from 0 to 63. The higher the value, the higher the
service level.
Appropriate setting of the network jitter addresses:
l Lip synchronization problems during conferences
l The increase of the network jitter value improves sound continuity
and solves the choppy audio problem.
