Specification (TSPEC) parameters are used to advertise information about generated traffic for Call Admission
Control (CAC) to the AP. The parameters are:
Minimum PHY rate
Surplus Bandwidth Allowance
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.

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.
