5 If DFS channels are used in the deployed network, in the navigation pane under
802.11a/n, select DFS (802.11h). Check the Channel Announcement radio box to cause
the AP to advertise Spectrum Management. If the AP does not advertise Spectrum
Management, Spectralink handsets will not connect on DFS channels (bandwidth shared
with radar facilities).
Admin Tip: Admission Control
Admission Control (ACM) must be enabled on both the Voice and Video AC when the
handset is configured for Admission Control Mandatory.
6 For Cisco 6.0, in the navigation pane under 802.11a/n, select Voice.
For Cisco 7.0 and later versions, in the navigation pane underneath 802.11 a/n, select
Media, then select the Voice tab.
7 Select the Admission Control (ACM) checkbox. If CAC Method is available, select
Static from the drop down list. Set the Max RF Bandwidth to 35 for 8020/8030 handsets
or 55 for 84-Series handsets to limit the bandwidth allocated to handsets to a value
tested to provide good performance. (If both handset types are present, use 45.) If
available, ensure that the Reserved Roaming Bandwidth is set to 6%.
