[VoIP] WE 2500 question

[Doug Alderdice]

I saw it yesterday, I think.  Definitely before today.  I am still looking 
for my add'l response yesterday to appear in my in-box about the 4-prong 
jacks clarifying in the last part of my posting that I was talking about 
subscriber loops:


"In my last message I wrote:
So, my grandmother's house aside, was the PSTN ever a 4-wire system?

Very early Strowger switches (c. 1900) had more than two wires but I don't 
know the details offhand. Bell System lines have always been two wires 
(plus a ground for party line ringing), AFAIK.

I am referring, of course, to lines delivered to the subscriber.  I didn't 
make that clear."



Doug.
