Since a few weeks ago (or was it a few months? :-) there was a
discussion about the Ramparts article on how to make your own "black
box", I thought everyone on the net might be interested to know that
in the latest issue of IEEE Spectrum (November, 1990), on pages
117-119, there's an interesting article entitled "The Great Blue Box
Phone Frauds", subtitled "Until the phone company separated signaling
information from the voice signal, long-distance calls could be made
without charge by anyone who could whistle at 2600 hertz."

It even has the illustration from the June 1972 "Ramparts" magazine,
showing how to constuct a "black box" to prevent the calling party
from being billed for the call.

There's also a list of about five or six other references at the end
of the article which sound interesting.

I'd type in the article, but it's a full three pages long. :-) If
someone with a scanner wants to do it, be my guest.  (I'm not sure
what the IEEE's policy on redistribution is, I couldn't find anything
in the TOC...)

For what it's worth,
