I'm not sure what "system" or "field" you're referring. The computers at
the centers and tracons have no idea if the transponder is ModeS or not.
They only process the beacon code and display the ACID that's in the flight
plan.
The centers and tracons don't have Mode S radars yet?

Some do, some don't. The problem is not the radar or the computer behind it,
bu the computer driving the displays that the controllers see: they don't
get the mode S data.
