Put a rest too? Not remotely!! The first paragraph states:
"Compared to the traditional voiceband modem, DSL technology uses much
wider bandwidth." It is a Sept 2001 article - show me something pre-1963.
Anything!
It's "traditional" because that's what the original one was. You got
nuttin!! And nobody ever disputed "modulation." The term is "modem."
So to REALLY put a rest to this, how about answer my original question:
"Are you saying that a DSL Ethernet Bridge connects to the PSTN network and
transmits data via the PSTN the same way that a Hayes modem does?"
If you say "no," which is the right answer, I win. If you say "yes," then
you are delusional, and I win.
Whadda ya say, Pops?
I'm calling for a community vote!

C'mon - everyone knows about the rift between you and your grandbrother...
:-p
Regarding the conversion from digital to analog signaling with DSL, here's
one reference for you:
http://www.ieee-cicc.org/2000/conference/edsessions/session3.html
Granted; there's no down-and-dirty detail here, but it's quite clear that
even the IEEE believes that DSL signals over PSTN require the use of A/D and
D/A conversion.
Also, here's a book that can bring all this to closure:
http://www.comsoc.org/ci1/Public/2001/Sep/cibrev.html
http://www.amazon.com/gp/product/0471290998/qid=1135889532/sr=11-1/ref=sr_11_1/002-9978780-2108045?n=283155
Note the generous use of the term "modulation" in the review alone.
Case rested...
Regarding "modem" etymology, any basic electronics tome that discusses
anything beyond DC/AC theory should be able to help there.
They're a bit difficult to transmit over email (as you might guess).
