It's not well defined in the legislation, and that is a problem, or certainly would be a problem if CSC were even capable of providing meaningful human contact of any kind to a substantial number of prisoners.
What we're finding is, however it's defined, even CSC is telling us they're not accomplishing it.
My own feeling is that meaningful human contact is something we should be concerned about defining. At least what we have to do is to make sure that people have some form of human contact. Then we can worry about how to make it more meaningful and perhaps more human. At the moment, we're not even getting there. We're not even at the first step, let alone defining how good it is.
