Hi:

EDT [European Deaf Telephone] and EDTN are the TDD protocols used in
Switzerland. Where can I find technical information about the EDT/
EDTN? Also, I would like to hear some tones resulting from the remote
EDTs/EDTNs located in Switzerland. I live in USA, so if I dial an EDT/
EDTN number to Switzerland, I will hear both the EDT/EDTN tones as
well as the tones resulting from negotiations among international
telephone exchanges. Those textphone and international exchange tones
give me an eerie feeling which I enjoy. I get a feeling of pleasant
fear. Its give me a psychedelic sensation. I like it. The tones are
scary yet fun -- much like virtual reality, a roller-coaster, or a
trip to outer space!

If I could find accurate recording of those tones [tones from remote
Swiss EDTs/EDTNs and international exchange negotiations] on a website
in Wave format and at least 44.1 kHz sample rate and 16-bit, then I
would just download those tones and listen. Unfortunately, no internet
site has recordings of those tones.

In addition, can EDT/EDTN signals be used as a form of dial-up
internet access? Obviously it won't be any faster than other dial-ups
-- most likely a max of 56 kbps. The sounds would be different from
currently-used dial-up modems, though. This is because EDT/EDTN uses
different types of signaling than most 56K dial-up modems.

Also, what does EDTN stand for? From what I was told in
http://groups.google.com/group/rec....AEARYt3Jalo6NNUi8Jt6wYH6Ba_Ois7NjCgNKwU1jjERM
, it stands for "European Deaf Telephone Network." This information
could very well be wrong, given that the poster seems to have a
personal vendetta against me.

I googled "European Deaf Telephone Network" in
http://www.google.com/search?hl=en&q="European+Deaf+Telephone+Network"&btnG=Google+Search
but only came up with two searches containing my previous posts. This
is extremely frustrating!!!!


Thanks,
