Yes, as far as I know it is the same 'basic' system based on the same software, but tweaked for the DFS 'wishlist'
Maastricht has 'turned off' a lot of the potential functions in order to get the system online quicker & to make it more stable. From what I have heard DFS want all the bells and whistles from the get-go, which could be the reason for the extended delays.
Another interesting point which I have heard is that the generic software was actually designed for APP. control, rather than ACC.
