thanks so much for this great article. Like many I am sure who used the Internet before it became the WWW this data does not surprise but it is still astonishing - if that makes any sense :) the first modem I installed was a 1200baurd connecting a 3174 to a FEP, I worked with a guy who was training me that could tell which dip switches were set by the tones on the line so all that noise was useful to some :) I tenner saying to someone once when the 56kbps Modem first came out "there is no way they will squeeze more speed out of a phone line" then a little while later I had ISDn at home and then the ability to bond the channels of my 128k I was amazed. I tell my kids this and they glance up from one of the 5 devices they each have connected and look at me like I am a dinosaur - hey maybe I am :)
