    Telephone Ring Suppression

    Not Home Automation related, but I don't know where else to turn....

    I have a repro vintage "french" style telephone. It's gorgeous, but the ringer is downright jarring. I cannot keep it hooked up until I find a way to turn off the ringer.

    I seem to recall a phone cord that had a switch inline with which you could turn off the ringer. But for the life of me, I can't find one anywhere online, nor in Radio Shack. I'm probably just screwing up the search term. Can any of you help me out here? If I'm wrong, can you at least clue me in to a modification I can make?

    Thanks

    Would think you could install a switch and find a discrete location to mount it--maybe on bottom? There are some ideas in this forum discussion. https://www.candlepowerforums.com/vb...=1#post2359794

      Depending on how your phone is wired, Red or Yellow is usually the RING. You might try disconnecting one at a time to see which one it is.

        I think most ring suppressors just shunted the 20Hz ring signal to ground though a capacitor. This would prevent any phone in the house from ringing so probably not what you want anyway. Your best option is to disconnect the ringer if you can access it.

          Jimspy,
          built this a long time ago. could not find my schematic, but found it back on the forum. I'm saving a copy of it this time. I would turn the relay on at night and the phone would be silent, yet you could pick up the phone and dial out at any time.

            Sandman sells a Ringer Cut-off for $29.95. They sell a version with a relay and a power supply for $38.95 that you could use with a controlled outlet if you wish to automate the ringer control.

              I think that's exactly what I'm looking for. BUT...it says "phones", not phone. This doesn't cut off all the ringers, does it? No, of course it wouldn't, the rest of my phones are digital with electronic ringers, this is the only analog phone. Great! Thanks!

                When you call to order they are pretty good about answering questions so you can tell them what you want to do and they should confirm this will do it.

                  Install it inline just in front of the analog phone and it will stop only that one phone from ringing.

                    Here is a circuit that block the 90 volt AC current that tings the phone. It allows the 48 volt DC to pass through but blocks the 90 volt AC used to ring the phone.

                      That's a neat circuit but it won't do the trick in this case as it prevents all phones on the line from ringing by "tricking" the local exchange carriers equipment into thinking that someone has picked up, thus stopping the ring signal at the source. In other words, it does not block the 90 volt AC current. Instead it causes the LEC to stop sending the signal. This means that none of the phones on the line will ring. Jim has indicated that he wants to silence only the mechanical ringer on one phone while allowing the other phones on the line to ring as normal. The circuit posted by Stuart will do this. It is essentially the same circuit in the Sandman devices. So it's build it or buy it.

                        Trust me, it's buy it.

                          Yeah, that's a little above my pay grade. But thanks.

                            How did you work this out? Just curious.

                              I went with the Sandman. At first they sent me a "non-operational" version, but we straightened that out right away and they sent me a good one. It's worked perfectly ever since. It's just a CAT 4 cord with a slide switch inline. Slide it to "off" and the ring is suppressed. I recommend.
