Almost 30 years ago, I worked on a corporate campus with several different buildings spread out over about 5 miles. There was a SONET ring linking them. I remember a coworker showing me this add-drop multiplexer thing so he could provision a fractional T1 of bandwidth out of the ring. CSU/DSUs, thick serial cables, cisco 2501 routers... We'd laugh at these speeds today. |
