n this presentation we dig down deep and find out how T1/E1 works at the signal level. We will cover frequencies and speeds, how data is framed and error checked, how digital and analog channel signaling is carried, and how timing is propagated and recovered in the system. This will be a live demonstration using various mechanisms in DAHDI to explore these topics.
