3 Click the QoS Policy tab.
4 From the Wireless QoS list, select the following:
● Legacy – Select if your WM-AD will support legacy devices that use SpectraLink Voice Protocol
(SVP) for prioritizing voice traffic. If selected, the Turbo Voice option is displayed.
● WMM – Select to enable the AP to accept WMM client associations, and classify and prioritize
the downlink traffic for all WMM clients. Note that WMM clients will also classify and prioritize
the uplink traffic. WMM is part of the 802.11e standard for QoS. If selected, the Tu r b o Vo i ce and
the Advanced Wireless QoS options are displayed.
● 802.11e – Select to enable the AP to accept WMM client associations, and classify and prioritize
the downlink traffic for all 802.11e clients. The 802.11e clients will also classify and prioritize the
uplink traffic. If selected, the Tu r b o Voi c e and the Advanced Wireless QoS options are displayed:
● Tur b o Vo i c e – Select to enable all downlink traffic that is classified to the Voice (VO) AC and
belongs to that WM-AD to be transmitted by the AP via a queue called Turbo Voice (TVO)
instead of the normal Voice (VO) queue. When Tu rb o Vo i ce is enabled together with WMM or
802.11e, the WMM and/or 802.11e clients in that WM-AD are instructed by the AP to transmit all
traffic classified to VO AC with special contention parameters tailored to maximize voice
performance and capacity.
5 To define the service class and DSCP marking for the WM-AD, select the Priority Override
checkbox. For each DSCP you can select one of the eight service classes.
● Service class – From the drop-down list, select the appropriate priority level:
■ Network control (7) – The highest priority level.
■ Premium (Voice) (6)
■ Platinum (5)
■ Gold (4)
■ Silver (3)
