How does the ATTESA E-TS 4WD work and do any other gt-r's or different car use it?

So i've been having this question for a while now,looking for people to know what it is,some don't really know (LIKE ME) and others don't really explain it very well and its kinda confusing me over,even looking into some car related forums.and im also wondering if the 34 has it
