The TC radar displays do not yet have the facility to interrogate the airframe id/aircraft registration database to match up that Mode S parameter and display the a/c reg from the database.
All it can do is code/callsign convert mode A codes from known flightplans or other codes that are manually input into the system.
So for now discrete mode A codes are still required, unfortunately. I get the feeling that the facility is not going to appear in the near future, neither.
