Spectralink VIEW Certified Configuration Guide: Cisco Controllers and APs
DFS Channels
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).
Media (Voice/Video)
For 84-Series handsets Admission Control (ACM) must be enabled on both the Voice and Video
AC when the handset is configured for Admission Control Mandatory. PIVOT handsets support
Admission Control on version 1.5 and later.
To enable Admission Control (ACM):
1 In the navigation pane underneath 802.11 a/n, select Media, then select the Voice tab.
2 Select the Admission Control (ACM) checkbox. If CAC Method is available, select
Static from the drop down list. Set the Max RF Bandwidth to 55 to limit the bandwidth
allocated to handsets to a value tested to provide good performance. If available,
ensure that the Reserved Roaming Bandwidth is set to 6%.
