Unlike a certain other manufacturer which rhyme with Crisco, Adtran has included a very nice 3-ring binder with a bookfull of very high quality instructions for your benefit.

RTFM. It's an easy book

If I were in High School, I'd do a book report on it. It's easy reading and describes the basics of operating this high quality computerized switching equipment. Do NOT ask me for tech support, as everything I learned about this is from the book, or poking around the menus in the adtran, after reading the book.
