    4 prong telephone jack adapter
    I have an antique telephone that has a 4 prong jack. Is there an adaptor that I can plug my phone in then lug it into the wall?

    How antiuqe is the phone? A 4 prong is that same thing in use today. Its just the wires are a lot smaller. It usually only takes 2 wires to run a phone. The reason for 4 wires is so it can work with either line 1 or line2 in a 2 line system.

    This is the original phone where you hold the listening device while speaking into the phone. This is the original not a replica. It is a rotory not a touch tone. It has a 4 prong plug attached. A black, red and white wire.

    You might want to contact your phone company just to make sure the voltages that it uses are compatible with current technology being used. Is there a dial on it or a crank?

    Found this:
    4-prong to RJ11 adapter
    Check out the phones through the Decades, may find yours.
    Haven't found the pin for pin yet.
    Personally I would trial and error connect to an active pair, The correct pair will give a Dial Tone.
    It may even be Polarity Conscience
    Good Luck

    If you need the info, I can remove a jack and look. I have plenty of these things working around the house.

    That adapter is the way to go. The 4 prong jacks generally have relatively noisy connections.

    Historically, the modular jacks were added next to existing 4-prong jacks at home.

    Some older touch-tone jacks are polarity sensitive. You'll get dial tone, but no keypad tones if the polarity is backwards.

    He sells them for about ten dollars plus four more for shipping. It's a really good deal, don't buy from the guy with the 34.00 ones!

    I mention Ebay all the time, the link I mentioned is actually cheaper, $12.00+$1.75 for Shipping= $13.75. You get to save a quarter, don't have to bid against anyone, plus the site has a lot of info for old Telephones.
    Unles you are trying to keep it original, I might consider changing the line cord on the phone, you can plug in anywhere and you don't need an adapter.

    Hi,

    I have a 4 wire telphone jack a bell 549A that uses a 225a converter to a RJ11 jack. Do you know if it matters where the red and green wires are connected to on the block?

    The line colors are red/black and green/red. The red/black is line 1 and the green/red is line 2.

    The third paragraph explains the connections. The block should be marked R, Y,
    G and B.

    I do suggest replacing the jack with an RJ11. I have had poor luck with the 4 prong females because they are usually mounted close to the floor. The RJ11 to 4 prong female seems to work a lot better.

    Newer terminology would be T1, R1 and T2 and R2.
