14. In the Max Admitted MUs for Voice Traffic field, specify the maximum number of MUs allowed

to connect to the specified radio for voice traffic. Limiting the number of MUs can ensure that
all voice MUs receive enough bandwidth to ensure voice quality. Admission control is only
available for TSPEC enabled voice clients.

15. In the Max Roamed MUs for Voice Traffic field, specify the maximum number of voice MUs that

are allowed to roam to this radio. Limiting the number of MUs can ensure that all voice MUs
receive enough bandwidth to ensure voice quality. Admission control is only available for
TSPEC enabled voice clients.

16. In the Max Airtime for Voice field, specify a maximum percentage out of the radio's total

airtime that may be used for voice.

17. In the Max Airtime for Reserved for Roaming field, specify a maximum percentage out of the

radio's total airtime that may be used for voice MUs which roam from other APs.

18. Refer to the Status field for the current state of the requests made from applet. This field

displays error messages if something goes wrong in the transaction between the applet and
the switch.

19. Click OK to use the changes to the running configuration and close the dialog.

20. Click Cancel to close the dialog without committing updates to the running configuration.

Configuring rate settings
Use the Rate Settings screen to define a set of basic and supported rates for the target radio. This
allows the radio to sync with networks using varying data rates and allows the radio to default to a
predefined set of data rates when higher data rates cannot be maintained.

Beacon Interval

Specify a beacon interval in units of 1,000 microseconds (K-us). This is a multiple
of the DTIM value, for example, 100: 10. (See "DTIM Period," below). A beacon is a
packet broadcast by the adopted Access Ports to keep the network synchronized.
Included in a beacon is information such as the WLAN service area, the radio-port
address, the broadcast destination addresses, a time stamp, and indicators about
traffic and delivery such as a DTIM.
Increase the DTIM/beacon settings (lengthening the time) to let nodes sleep
longer and preserve battery life. Decrease these settings (shortening the time) to
support streaming-multicast audio and video applications that are jitter-sensitive.
Default is 100 K-us.

DTIM Period

Specify a period for the Delivery Traffic Indication Message (DTIM). This is a divisor
of the beacon interval (in milliseconds), for example, 10 : 100. (See "Beacon
Interval," above). A DTIM is periodically included in the beacon frame transmitted
from adopted Access Ports. The DTIM period determines how often the beacon
contains a DTIM, for example, 1 DTIM for every 10 beacons. The DTIM indicates
that broadcast and multicast frames (buffered at the Access Port) are soon to
arrive. These are simple data frames that require no acknowledgement, so nodes
sometimes miss them. Increase the DTIM/beacon settings (lengthening the time)
to let nodes sleep longer and preserve their battery life. Decrease these settings
(shortening the time) to support streaming-multicast audio and video applications
that are jitter-sensitive. The default DTIM period is 2 beacons.

Self Healing Offset

When an Access Port increases its power to compensate for a failed Access Port,
power is increased to the country's regulatory maximum. Set the Self Healing
Offset to reduce the country's regulatory maximum power if Access Ports are
situated close to each other or if Access Ports s use external antennas. For
additional information on determining the offset value, see the documentation
shipped with the Access Port.
