While you're right that there is no more data able to be carried by the MU and COMM lines, CAD/AVL data is shared amongst the cars via the Cat5 bus line. All of the CEM cars have it installed from the factory.
The problem now is that the program to upgrade all of the old cars with Cat5 has been cancelled.
Oh I definitely didn’t know the full story, my bad thanks for the correction
