This object is used to enable or disable admission
control for voice traffic flowing through the 802.11a
interfaces in the controller.
When set to 'true', controller will reserve and manage
max-bandwidth (cLQd11aVoiceMaxAdmBandwidth)
and roaming-bandwidth
(cLQd11aVoiceMaxRoamBandwidth) as per user
configured values.
When disabled, admission control will not be enforced.
This may delay voice traffic depending on load on
the WLAN.
