The name I gave when I called the developer was one I still remember: Marnix van Ammers, the name of a real Pacific Bell switching engineer. I gave him the same story about needing to do some integration with our SAS units. "I’ve got the user’s manual," I told him, "but it doesn’t help for what we’re trying to do. We need the actual protocols that are used between the SAS equipment in our testing centers and the central offices."
