Well, you can still do that, but you need something to do the ringing. If each cable is a home run to a common point, or you have enough pairs, the quickest is to spring about $250 or less on eBay for a Panasonic KX-T PBX. A TA-824 would give you 8 extensions, or, since it's intercom only and you don't need features, you could grab a TA-anything, or a 30810 or a 61610.
There are some common path intercoms that would do the trick, but you need a power supply and buzzers and extra pairs to ring the buzzers, so by the time you fooled around with that, the Panasonic route would be the best. You might also grab a Partner ACS 1.0 system. 3 lines 8 extrensions in a box.
If you want to go the Panasonic route, drop me an email. I have a couple of sytsems in the warehouse that I'll let go for cheap.
Well, if you want to have a neat phone system on your home you may want to ask your phone company if they offer a home phone system. Such phone systems are cheap nowadays.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
