VOIP/Dialup emulation

Data, was, in fact, transmitted over phone lines in the 19th century. Look up "telautograph" and the history of FAX. Older than you think.

Wow!

Boy, I knew that still using dial-up daily made me an old fogey, but my generation definitely did NOT send data over a 19th century network... ;-)

Hah! Funny!

It all depends upon what you mean by "data". In my youth, the QA lab, shipping and the line operator exchanged information via telautograph in a steel mill. That, I submit was data--and the telautograph and telephone have a direct tie-in to Elisha Gray. Ticker-tape machines date back tot he 1860s and if stock prices aren't data, I'd like to know what they are.

No fancy carriers or modulation needed, since telephone and short-haul telegraph lines were essentially DC connections between the endpoints.

Not exactly the "telephone" wires we've come to know today (local battery vs. common battery), but that is still very interesting. I know early teletype/ticker type stuff has been around forever, but had never seen the "telautograph" before. Guess I hadn't considered those technologies! Very cool stuff, thanks for the education.
