Thanks. I already read

There is info about EDT but absolutely nothing about EDTN.

What does ETDN stand for?

Where can I find technical info on EDTN?

It’s so frustrating when I so extremely interested about a subject and
am not able to find info about it!

This is so interesting. Please don’t feel insulted by the cross-posts. I
only posted to relevant NGs.

No offense but please respond with reasonable answers & keep out the
jokes, off-topic nonsense, taunts, insults, and trivializations. I am
really interested in this.

I am so interested in what EDTN stands for and how it works. Yet I am
also extremely frustrated because I can’t find any additional
information on this topic.

I’ve tried painfully hard to answer my questions doing my own research.
I still haven’t found answers to my questions. That is why I am turning
to NGs for assistance.

From what I was told in
http://groups.google.com/group/rec.audio.tech/msg/fe2558b1edeb31c8?hl=en&utoken=4AIZ
Yi4AAAAI2PeJr_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. Given that he/she hates me it’s highly likely that
he/she purposely gave me the wrong answer just to shut me up.

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 6 searches containing my previous posts. This is
extremely frustrating!!!! I can't believe I am the only one who is
interested in EDTN!


Thanks in advance for your assistance, cooperation, and understanding,

Radium
