Traffic Specification (TSPEC) parameters are used to advertise information about generated traffic for
Call Admission Control (CAC) to the AP. The parameters are:
•
•
If your wireless LAN has access points that use 802.11b and you plan to use Call Admission Control
Note
(CAC) with TSPEC, then you need to modify the PHY rate to a supported rate for your 802.11b access
points.
To make changes to the advanced settings, follow these steps:
Procedure
Choose the network profile that you want to configure.
Step 1
Click the Advanced Profile link at the top of the page.
Step 2

Minimum PHY rate—Lowest rate that outbound traffic is expected to use before the phone roams
to another AP
Surplus Bandwidth Allowance—Fractional number that specifies the excess allocation of time and
bandwidth above application rates required to transport a MAC service data unit (MSDU) in a
TSPEC frame.
If you are using 802.11b APs and plan to use Call Admission Control (CAC) with TSPEC, then
set the PHY Rate to a rate that the APs support such as 11 Mbps.
