Phones normally use just two wires. Hook up the red and green wires and forget the yellow. Most of the time the phone wires will only have areound 12 volts on them. While the phone rings there is around 90 volts on the line. This voltage probably will not kill you but it sure can be painful. |

I once found 5 of them plugged into a basement, in a 100 year old home. stuck up in the cieling. i was attempting to troubleshoot a DSL problem and got a tingle off the yellow wire. since there were no lighted phones they were just a energy waste and perhaps a fire hazard. Does your phone havve a NID outside? if it does unplug your home while connecting new jack, so you dont get a nasty but not life threatening shock while working on things, or at least take another phone off hook so line is busy, ringing is the nasty shock |

You only need 2. Pick two that are good and go with them.

Lots of abandoned wiring in most old houses. Look in the basement, and try to see where the wire comes out, and see how many colors it has there. 3 color phone wire is rare, likely the black was clipped off on the kitchen end. Loosely attach a phone to the kitchen end, red and green, and see if you have dial tone. Old real (ma bell) phones often used the yellow as a ground line (IIRC, red went to L1, green went to L2, and yellow to GND). Modern disposable phones probably don't care. A pair of alligator clip leads, or better yet a rj11 breakout connector (jack to several alligator clips) comes in handy, if you don't have a butt sett, aka lineman phone. Don't be surprised if the line is garbage, and you need to run new wire. If you do, resist the temptation to disturb the old wire and install a splice- run it all the way back to where the wires come together on the terminal block. If you don't have an outside demarc box, call phone company and hint you want them to install one. That sometimes will get you a fresh drop from the pole, and gets you a nice fresh connector block to play with. You have my sympathy- the inside wiring in this place is garbage, and I really need to redo it. But since I now have DSL on a separate pair, and nobody ever calls me, it isn't likely to get tp the top of the list anytime soon. -- aem sends... |

My house (built about 1974) has 3 wires, red/green/yellow. It was probably just what wire the builder had. Unless you're on a party line, phones just need red and green (these connect to the middle 2 wires in the jack).

Rip out the old wires altogether and put in a new modular wire system, all the way to where the phone company wire enters the house. |

When the tel companies were deregulated, years ago. My Dad bought a little
book on phone wiring. I remember it saying 48 volts DC when the phone is not in use "on hook" and about 5 volts DC when the phone is in use "off hook". 90 VAC ring sounds correct. -- Christopher A.

You only need the red and green wires: The other two aren't used. When the phone isn't being used, there is arounc 48V DC between the wires *red negative w/r to the green). When the phone is picked up, that voltage drops to around 9 to 15 volts, depending on a few things. Ringing voltage is nominally 90 Vac riding on top of 48V DC so it's capable of giving a person a really good kick if you'r handling the wires when the phone rings! So, disconnect the wires from the point where they enter the house; there should be a box there where they can be disconnected. If not, then leave a phone off hook while you do the work. That will set off an alarm in the central office and the phone will loudly complain for awhile, but it stops after about 30 seconds and then the central office just removes power from your phone lines. In this case, it might take up to a few minutes of the phone being back on hook before the central office system gives you back your voltage and dialtone. Normally it's a pretty quick change but some older offices can take quite awhile to return your service. Test the phone after installing hte box. Try dialing a number from another phone too. If the new phone "tinkles" when the other phone dials out, then just reverse the red and green wires and it'll stop the tinkling. It's not unusual for the red & green wires to be reversed in old installations like you have. HTH |

More than likely, all you need are the green and red wires. The black and yellow wires would be used for a second line if you had one. In a normal residential system, they are not used, even though they may be hooked to terminals as if they are. A telco will NEVER use the yellow and black lines for a second line with a normal RJ-11 installation. Those are for lights and grounds in key systems, etc.. |

If you have one line, then the voice comes in through green and red, tip and ring respectively. The yellow and black are for other things - a second line (if you have one) or for the dial light on fones like the Princess which is powered by a transformer plugged into an outlet near the fone. Modern fones don't need the yellow wire for the dial light, these take the power from the green and red wires. You'll want to have another extention off the hook when you work on wiring, because the ringing voltage is 90VAC at 20Hz. In other words, when somebody tries to call you you'll get a painful shock. |

That really becomes apparent if you have a modem on one of those pairs. The carrier will bleed over. One more time. If a person calls the phone company and asks to change the existing extension phone in the upstairs bedroom of their 1960's raised ranch to a second line, the telco will come and use the existing 2-pair wiring and use the "unused" yellow/black pair for the second line. The assertion that telcos NEVER do this is pure unadulterated BULL-OH-NEE. New installations are no longer done with JK 2-pair They now use cat 5. The OP has described the wiring in their new OLD house as being 2-pair with one of the second pair clipped off or missing. There is no blue/blue-white or orange/orange-white there. Does not exist. As I corrected stated, they do not need the black and yellow wires at all unless they want a second line. I told them they just need the red/green pair for what they asked about. |

I've seen them use wire nuts or twisted wires covered with electrical tape to make their connections. Of course, when it is at the consumer's expense, then they insist on doing everything up to standards.

If that's what you happen to have and you are on a party line, then, sure, use the yellow wire for selective ringing. That is NOT however it's official designation ever since the advent of 2-pair wiring - OVER FIFTY YEARS AGO.

More than likely, all you need are the green and red wires. The black and yellow wires would be used for a second line if you had one. In a normal residential system, they are not used, even though they may be hooked to terminals as if they are. A telco will NEVER use the yellow and black lines for a second line with a normal RJ-11 installation. Those are for lights and grounds in key systems, etc.. Wrong. It is quite common. Most recent time I ran across it was in this very house, where the kid's bedrooms were wired with yellow and black to the center conductors. Pre-cellphone era, Mama Bell heavily sold getting a second line for the kids. Was also quite common with roommates sharing a house (like at college) and wanting private lines to talk to their sweeties, and to make sure there was no question about who pays LD charges. (Back in school, I used to do a lot of moonlight phone wiring for young ladies. Nothing illegal, mind you, just putting outlets where they wanted them.) -- aem sends... |

Ask a hard one- that is the 4th row of buttons for an old AUTOVON phone. The TT standard was written around a 16-key (4x4) array. Somewhere in my collection, I have an old gray 2500 without the star and pound keys. Back in the 50s and 60s, the dividing line between ATT, WE, Bellcore, and Army Signal Corp, got rather fuzzy in spots. DoD was heavily involved with the post WWII design of the long-lines buildout. They even used to have a special area code assigned for the government emergency comms- now it is just a front door to a virtual network, with a single phone number assigned to it. -- aem sends... |

My understanding is that the letters were found on military phones connected to the AUTOVON phone systems that's no longer in use.

I was talking to someone today about my great uncle who was a lifer in The US Army Signal Corp. He joined when they were still using two tin cans and a string and I'll bet he was familiar with the AUTOVON system. [8~{} Uncle Monster |

I also haven't seen an interior phone wired by a real telco installer repairman in years either. They are usually contractors who are basically clueless. Back before the US v ATT decision if you had 2 lines, they ran 2 cables or a 25 pair if you were in an office that might get a call director phone. BSP said you did not run 2 lines in one cable without using twisted pair. IF the telco installed a demarc box, that is true. However, at least in my area, a lot of homes were missed. If the owner of such a home calls for a line problem today, the telco is required to repair the line even if it is inside the home, at least up to the junction blocks installed by the phone company back in the ancient past. That is where you will find the funky repairs I was describing. The technicians who make these repairs may well be contractors for the telephone co, I don't know. The telco won't install a demarc box on such a home without a lot of persuasion. I guess their bean counters figure it is cheaper to just repair the wiring, than to repair the wiring AND install the box. -- There is always an easy solution to every human problem -- neat, plausible, and wrong."

The next time you will pay a trip charge. In real life I have not seen a house without a Dmark in almost 30 years.

A telco will NEVER use the yellow and black lines for a second line with a normal RJ-11 installation. Those are for lights and grounds in key systems, etc.. You are wrong. This is very common in residential installations. People have a second line for the kids or whatever and it goes on the yellow and black wires. You can't read: READ what I said: "A telco will ... ". Using those wires for a phone line can of course be done. ANY wires could be used. But you'll never get a telco to work on them ever again; all they would offer to do would be to rip it out and replace it with properly wired system. Up your reading comprehension skills. Hell, I could use 10 ga green wires if I wanted to. But come back to earth Scottie. You are still wrong. The telco uses yellow/black for a second line in residential installations. It would make no difference who does the inside wiring, as the telco would still be the ones to wire it THAT WAY where it enters the house. If you take apart any modern analog 2-line phone, you will discover that it is MANUFACTURED to expect the second line to be on the yellow/black pair. Gee, I wonder why? Please also not that when JK wire is diagramed, the wires are labeled: green =tip 1 red=ring 2 black= tip 2 yellow ring 2 Case CLOSED You're bound determined to justify it aren't you? What you showed is not a RJ-11 jack which is what would be used in the home. If you plug any residential phone into a jack such as you described, it will not work from the yellow/green wires. It will work from the tip/ring pair at pins 3 & 4 ONLY. You also left out pins; there are 8 on the wiring you showed, which is shown incorrectly. Telephones do not come with some wired for pins 3 & 4 and others wired for other pins: In fact, very often the silver & gray telephone cables only consist of 2 actual conductors. If you were to try to use the yellow/black for tip & ring, you would have to terminate those wires in hte jack the phone connects to at the normal positions in the box for the red/gree pair. so the yellow wire would go where it says red and the black to where it says green. Clearly wrong. If a telco wires in a 2-line system, they will not use 6-conductor standard phone cable but will use 8 conductor instead, and 8 pin RJ jacks vs the 6 pin RJ11 jacks. The specs dictate that so that, where the wires are no longer twisted within the jacket of the cable, a distance can be maintained between them to keep line to line crosstalk from occurring. I detest misinformation and especially when it comes from some moron who guesses at what the rules and regs say and want to justify their own existance by giving incorrect information. Whether you looked up "tip" and "ring" or just think they were handy buzz words, they are very real and have distinct meanings within the installations. You CAN connect another line to the black/yellow pair, but then you'll have some phones that don't work and need rewiring at the box, and a very good chance of crosstalk between the two lines, especially since I doubt you would know how to keep non-twisted sections short and the rest of the things any novice installer would know. If youwant the nitty gritty it exists in the CFR, Title 47, Part 68. Go educate yourself or quit giving out misinformation that can cause other people problems. NOW the case is closed because I've no more food for you to troll on; you're on your own. |

I have seen telco technicians do all kinds of things in residential wiring, including using black/yellow pairs, even green/black or red/yellow, or most any other permutation, if it helps them avoid stringing a new wire at telephone co. expense. I've seen them use wire nuts or twisted wires covered with electrical tape to make their connections. Of course, when it is at the consumer's expense, then they insist on doing everything up to standards. Please don't generalize what is probably best practice to what is actually being done the field. Since the late 70s, all interior wiring belongs to the consumer. Which was a real blessing! They will still do the wiring though, if you want them to. And you're right, these days they have a cadre of "approved" contractors do the wiring. But it's not cheap. It used to be done by their own technicians "back when" but no more. You can even do your own digital wiring these days of course and it's much easier and a lot clearer what to do now; you almost can't go wrong with digital except that there are so many different kinds. For those, excepting some DSL lo speed stuff, you really have to have CAT5 or the new CAT6 depending, or the lines just won't work well. I ran new CAT 5 for all my wiring as soon as I discovered we were goint to get DSL so I don't know how bad it gets with the old wiring. Pretty bad I imagine, esp if it's old enough to not be twisted pair cable. I haven't seen it, but I understand you can even get CAT5 or 6 cable with a sheath for grounding; I guess Faraday lives on! Cheers, Twayne You don't get anything at telco expense anymore. I also haven't seen an interior phone wired by a real telco installer repairman in years either.
