The timer will be started if T1 has been reset (for one of the reasons listed under "T1"

no outstanding acknowledgments or responses from the local link station.
If the local station does not receive an LPDU before Ti expires, the station must send
an LPDU with the P bit set to B'1' to solicit the remote station's status. Recovery then

This parameter is used in conjunction with T2 to allow stations to reduce traffic. A
