Configuring Voice and Video Parameters
TSM can be configured through either the GUI or the CLI on a per radio-band basis (for example, all
802.11a radios). The controller saves the configuration in flash memory so that it persists across reboots.
After an access point receives the configuration from the controller, it enables TSM on the specified
radio band.
Note Access points support TSM in both local and hybrid-REAP modes.
Using the GUI to Configure Voice Parameters
Follow these steps to configure voice parameters using the GUI.
Step 1 Make sure that the WLAN is configured for WMM and the Platinum QoS level.
Step 2 Disable all WLANs with WMM enabled and click Apply.
Step 3 To disable the radio network, click Wireless and then Network under 802.11a/n or 802.11b/g/n, uncheck
the 802.11a (or 802.11b/g) Network Status check box, and click Apply.
Step 4 Click Voice under 802.11a/n or 802.11b/g/n. The 802.11a (or 802.11b) > Voice Parameters page appears
(see Figure 4-17).

Step 5
To enable bandwidth-based CAC for this radio band, check the Admission Control (ACM) check box.
The default value is disabled.
Step 6 To enable load-based CAC for this radio band, check both the Admission Control (ACM) check box
and the Load-based AC check box. The default value for both check boxes is disabled.
Note The Load-based AC check box applies only to non-mesh access points because mesh access
points do not support load-based CAC.
Step 7 In the Max RF Bandwidth field, enter the percentage of the maximum bandwidth allocated to clients for
voice applications on this radio band. Once the client reaches the value specified, the access point rejects
new calls on this radio band.
Range: 40 to 85%
Default: 75%
