-------------------------------------

we just bought this house and want to put a phone in the
kitchen..unfortunatly, the wires are bare....now we bought the jack
and went to install it, and found that there are only three wires
coming out of the hole, red, green and yellow..no black,,,
how can we install this new jack to an old line that has only the
three colored wires?



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..


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


That is what an RJ14 jack is labeled but when you use the yellow/black
as the second line you get crosstalk. 2 line station wire will usually
be blue/blue-white, orange/orange-white twisted pair. 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.
