   Correct me if I'm wrong, but my memory from altogether too recently is that
the ring signal is a 90+VAC signal, at 17hz.  Current, I have no information
on.  The shock was never particularly bothersome to me, and I've been hit more
times than I can recall.  Of course, electric shock affects different people
differently.

   As an aside, a local paper once printed an article originally appearing in
the NYTimes, explaining how to wire your own extension telephones.  They didn't
bother to mention the ringing signal.  I wrote in, noting that the application
of such a jolt to a person wearing a pacemaker, for example, could be more than
irritating...possibly deadly.  I suggested taking one extension off-hook
(48VDC) before attempting anything.  There were a number of other glaring
errors in the article, like the completely incorrect explanation of the 
two-four wire possibilities.  They printed it, and forwarded it to the NYT, 
who is rumoured to have also printed it... my journalistic debut.. :-)
