Hi,
I have a hairbrained idea that requires ring generation when all extensions on a classical analog telephone line are hung up. Aim is to use the extensions as an intercom within a big house. Once two extensions are "off the hook" they communicate OK. Rather then stupidly duplicate ring equipment, maybe I could just 'synthesize' or fake the ring signal??

I'm not sure of what you want to do. Post to comp.dcom.telecom.tech for some better informed telephone techs opinions.

You don't need any such complicated (and unworkable, for a variety of reasons) ideas. There are plenty of dial intercom modules, made by Melco, TelTone, and Valcom (just to name a few) that will do an admirable job of forming the core of your intercom system.
Poke around on Ebay for things like this:
Other stuff shows up frequently. Keep in mind that you will also need an appropriate key telephone system power supply, with a ringing generator if you want to use actual ringers, such as this one:
...or this one (a bit cheaper):
Outside of that, all you need are a few phones of just about any kind you want, some wiring, and some effort.
Happy hunting.

I used to repair those! I bought dead ones for $2 each, fixed about half of them, then sold them to people still using 1A2 type phone systems. I think I finally used up the last of them, but I may still have a box full of relays and the custom hybrid filters.
