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.

Also, what does ETDN stand for?


Thanks,

Radium
