* These procedures affect tokens only if the basic concatenation feature is requested by use of the
give-tokens or please-tokens parameter.
Note After you call APS_ACTIVITY_DISCARDREQ_ or APS_ACTIVITY_INTERRUPTREQ_ , the service
provider assigns all available tokens to you. This token assignment takes effect when you receive the
confirm primitive. (See the preceding description of “Primitives” for an explanation of the confirm
primitive.) However, the remote user can use the please-tokens parameter (the basic concatenation
feature) in the call to APS_ACTIVITY_DISCARDRSP_ or APS_ACTIVITY_INTERRUPTRSP_ to ask for
some or all available tokens to be returned.
