The following screen shows how the display would look when there are three APs
configured with an SSID that matches that of the Wireless IP Telephone. The first has a
signal strength of –28 dBm, is configured on channel 2, with a beacon interval of 100ms.
The second has a signal strength of –48 dBm, is configured on channel 6, with a beacon
interval of 200ms. The third has a signal strength of –56 dBm, is configured on channel
11 with a beacon interval of 100ms.

characters of the APs SSID instead of the beacon interval as in the example below.

Q:XP
X is a Hexadecimal representation of the access categories configured with admission
control mandatory (ACM). Bit3 = voice, Bit2 = video, Bit1 = background, Bit0 = best
effort. For example, if an AP advertises voice and video as ACM then X=c. If all the
ACs are set as ACM then X=f. If AP does not have WMM support, this character space
will be blank.
P is displayed when the AP advertises WMM-PS. If the AP does not advertise WMM-
PS then this character space will be blank.
