And after all ADS-B does not replace the need for a

question is how ADS-B integrated.

Some manufactorers claim that their mode S transponders will be
upgradable to ADS-B.

Ah yes. But what ADS-B? That is 1090ES which just about all Mode S
transponders now will support. Plug in a certified GPS and you should
have ADS-B Dara out over 1090ES but you may or may not have ADS-B data
in for TIS on that transponder and you cannot get FIS-B data services
(e.g. Weather info) over 1090ES, for that you will need a UAT.

I tried to make clear the ADS-B capabilities of the Trig and Becker
Mode S transponders is described in the transponder comparison table
