Well, no one answered these questions. It's very frustrating when I
have a question that is so interesting to me and I am not able to find
answers to it.

So please answer my questions.

I am interested in EDTN because its one of the types of telephone
audio devices no one talks about and it is used in Switzerland by
those with sensorineural deafness. I associate Switzerland with
frightening-yet-enjoyable high-technology magnetic telecommunications.
I don't know why, I just do. Sensorineural-deafness is accompanied by
a false-perception of a high-pitched sine-wave tone resembling the
"whine" of a CRT. Sensorineural-deafness is caused by damage to the
acoustic nerves responsible for translating mechanical vibrations in
the cochlear hairs to neural impulses that can be detected by the
brain. Since sensorineural deafness involves acoustic-nerve-damage and
the damage nerves are hyper-excitable, they
send crazy signals to the auditory cortex interpreted as sounding
similar to a CRT monitor. This is false auditory perception is called
tinnitus.

Anyways, the EDT/EDTN uses audio signals to communicate between one
EDT/EDTN device and another EDT/EDTN device. Just like one PC can
communicate with another PC half-way around the world using audio-
frequency signals via dial-up modems.

I've never actually listened to EDT/EDTN but I think I'll enjoy it.
I've listened to American TDD tones by dialing local TDD numbers

Dial 1-800-543-1586 and you'll hear the American TDD tones I am
talking about. This is an example of a TDD number used in the United
States. I want to hear the Swiss-equivalent of TDD.

Where can I find EDT/EDTN numbers? Please give me some EDT/EDTN
numbers. If that's not possible, please steer me to a website that
contains high-quality recordings of the sounds generated by EDT/EDTN
devices along with the international negotiation tones I would get
when dialing from USA to Switzerland.

High-quality = the sample-rate must be at least 44.1 KHz and the bit-
resolution must be at least 16-bit and the recording must be an
uncompressed linear-PCM wave file.
