My colleague is better placed to discuss the specifics, although I believe she is currently having some technical issues.
What I would say is that yes, as part of the agreement, Turkey has deployed a small number of troops. They're not a part of the peacekeeping mission, but they are more a part of a central operations centre that can help observe the operation as a whole. It is not a peacekeeping mission in the same way that the Russian one is, and it's on a much smaller scale.
