11.3 QoS
Network traffic can be classified by setting the ToS (Type Of Service) values at the data source
(for example, at the WiMAX Modem) so a server can decide the best method of delivery, that
is the least cost, fastest route and so on.
Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple
logical networks. Only stations within the same group can communicate with each other.
Your WiMAX Modem can add IEEE 802.1Q VLAN ID tags to voice frames that it sends to
the network. This allows the WiMAX Modem to communicate with a SIP server that is a
member of the same VLAN group. Some ISPs use the VLAN tag to identify voice traffic and
give it priority over other traffic.
Click VOICE > Service Configuration > QoS to set up and maintain ToS and VLAN settings
for the WiMAX Modem. QoS (Quality of Service) refers to both a network's ability to deliver
data with minimum delay and the networking methods used to provide bandwidth for real-
time multimedia applications.

SIP TOS Priority
Setting
Enter the priority for SIP voice transmissions. The WiMAX Modem creates Type of
Service priority tags with this priority to voice traffic that it transmits.
