ring generation

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:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3068495787&category=11908

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:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2584149676&category=32720

....or this one (a bit cheaper):

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3068616928&category=294

Outside of that, all you need are a few phones of just about any
kind you want, some wiring, and some effort.

Happy hunting.

Wow, I've got a couple of those KC-19s. I'll sell one for $20 plus
shipping. Email me, but observe anti-spam measures in .sig.

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.
