I know it's outdated, but the state is still expecting applicants to know it and it still on the State C-& exams.
I like questions like that- it separates the serious from the 20 something jackass IT types. A real phone person would know most of that or know where to find it. If you apprenticed in the trade and studied telecom history and/or have experience (like you are SUPPOSED to to take that test) I expect you would have come across it at some time.
