I Googled (is that a word) Jake Brake - even misspelled it and this one 
of the link that came up. It does a pretty good job explaining why they 
are baned many places and why if you use them - the locals will have 
your hide.

Ford - most likely Allison which is owned by Ford - has (and I think 
Chevy uses the same design in their five speed diesel automatic 
transmission, maybe even the same transmission) what they call tow haul. 
Disels are not very good a compression braking. That's why the exhaust 
brake, a.k.a. Jake Brake was developed for semis. In the tow haul mode 
the Ford (and Chevy) will enable the vehicle to use compression braking 
to slow you down or to keep a consistent speed going down a long grade. 
It works pretty well. I don't know exactly how it works but I suspect it 
has something to do with retarding the timing and maybe even closing the 
turbo off to restrict the exhaust while playing some games in the 
transmission.
