Got it.  Now let me get this right, there is a post out there which said
something to the effect that if you live far away from the switching
station (or whatever it is called) there is a possibility that you will
not be able to get 56K downloads from an isp due to signal loss.
True/not true?  If true, wouldn't a low noise amp in line do the trick?
If not true, where in the line does the signal degrade?  Is it in the
telco's switches?  If so, what's the cure?

I did some asking around and one person told me he thought the additional
two wires used the voltages to light the key pad of the first
"princess" phones.
