Radar control? No, still you in many countries.(You are still on own navigation) Vectors, the controller.
That said, I never issue DCT below MSA due to the fact that rules are different around the world. If I need to give a instruction early, I slip in a "through xxxxft........". (The fact that mb399 asks kinda sements that issue!)
Pierre indicates that the CAS structure provide TC. That is a very dangerous assumption. (And veeeery wrong some places!)
