TD-2.org is a private wiki on telecommunications infrastructure and history, recently launched by J. B. Crawford. The goal is to build a website along the lines of Albert La France's invaluable resource, but with multiple contributors and a plan for sustainability into the future. I am also aiming for a more convenient navigation experience, by using geotags and interlinking.
The scope of this website is civilian and military telecommunications in North America, and specifically the infrastructure used prior to the widespread adoption of fiber around 1990. While there is a heavy emphasis on the Bell System and AT&T long lines, that is not intended to be exclusive.
I've been thinking about launching this project for a long time, but only really got to it recently. You will quickly see that a lot of things are half-done, see To Do for a list of planned work (and there's a lot more to be done!).
