Hi:

I've posted this before but never got a rational scientific response.
Sorry for the repetition and any annoyance it causes but I am really
interested in this.

EDT [European Deaf Telephone] and EDTN are the TDD [Telecommunications
Device for the Deaf] 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.audio.tech/msg/fe2558b1edeb31c8?hl=en&utoken=4AIZYi4AAAAI2PeJr_MMmQkfz_j8PKAEARYt3Jalo6NNUi8Jt6wYH6Ba_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=%22European+Deaf+Telephone+Network%22&btnG=Google+Search
but only came up with two searches containing my previous posts. This
is extremely frustrating!!!! I can't believe I am the only one who is
interested in EDT/EDTN!


Thanks,
