Neat telco photos

Photo archive is here

"Secret Pictures of Phone switches" Features the 1AESS, DMS-100, and 5ESS.

While not completely pictures (mostly not pictures), su1droot said I should link to it. He's right. It's a cool site.

The Central Office. This contains photographs of the outside of central offices. Most of them are quite interesting.

Richard Patak sent me an interesting link showing cellular sites in Santa Cruz County

Consumer Advocacy

Resources for Michigan Telphone Users

MI-Telecom discussion list

Maine Public Advocate Office. This appears to be a really cool thing - a state office that represents consumers. Clicking on "ratewatcher" seems to contain items of interest to residents of other states as well.

"roamer1" has an interesting site on Cellular networks in the Southeast US

This is a interesting tutorial on how SS7 Switching works

ICB advocates for the toll free (and domain name) end user. While my site doesn't specialize in toll free numbers, ICB's does.

If you run a consumer advocacy site, please email me at [email-masked] and I will review it and add it here.
