Hi, I have 2 very old wood phones (Northern Electric) with bells and magneto (no dial) that are working... Just need to install batteries or transformer. I want to know if I can install them on my touchtone phone line (Bell Canada: red and green wires) to receive calls. If not, I would like to connect them together to make an intercom in my house. Maybe someone know how to do that.

Thank you!!

In Canada you can, but I don't know if you can in the States Pulse and DTMF both work here.. Red is the Tip Green is the Ring try plugging it into the jack or cut a phone cord and match them up and plug them into the wall and try it.. What type of phone is it does it have a crank??

Hi,
If they have what is called a "duplexing coil", they will work for incoming calls on standard telephone systems. Polarity is not an issue on incoming calls on these phones.

If you connect them to your regular phone line and can barely hear anything at all, or cannot be heard you need the coil.

If you do a metasearch like webcrawler, you will find a number of suppliers for parts of all types, and with minimal effort, you can get the basic parts to handle incoming calls if yours lack that special coil. If you really wanted to put them to use on a digital phone system (Merlin and up), there are boards available to make that possible too, just use the ones for the candlestick phones.

You will want to disconnect the hand crank generator, but it can certainly be left in place.

If you decide to use them as intercom, you need to maintain a 45 volt supply (tip voltage).

Hi, it's 2 crank phones... The first one is a Northern Electric 1916 model N317-F (or N1317-F?) with 2 battery wires and L1, GND, L2, COND, COND terminals inside the door. This one have an IND. COIL and the condenser can be connect or not. The second one is a N. E. N717CG with GND, L1, L2, C1, C2, BK and BATT terminals inside. Inside the first one, there is a wirering diagram. I can read: red ringer on L2, black ringer on L1. If no condenser, yellow on lower COND. Here we have a DTMF (I said touchtone, first time). Black and yellow wires not connected (no signal, not a ground). Red and green, connected to phone.

So, maybe I can try to connect Red and Green on L2 and L1 terminals? The 45 volts supply is DC? This supply do not come from the phone line?

Thanks,
J-F

Every Analog phone line supplies -48 VDC just try connecting the red and green polarity shouldn't matter.
