Specifies the amount of time that an active traffic stream (TS) in the downlink direction may be idle, from the perspective of the AP, before it is deleted by the AP. For a bidirectional TS, both the wsAPRadioTspecApInactivityTimeout and the wsAPRadioTspecStaInactivityTimeout must expire in order for the TS to be deleted by the AP due to inactivity. If either of these timeouts is disabled, the AP will not delete a bidirectional TS due to inactivity. This value is specified in seconds. Setting this object value to 0 disables this timeout.
