The colors do matter for anyone coming in behind you.
White/blue stripe = green - tip
Blue/white stripe or solid blue = red - ring
This makes up line one.
White/orange stripe = black - tip
Orange/white stripe or solid orange = yellow - ring
This makes up line two
The color code is:
White & blue = pair 1
White & orange = pair 2
White $ Green = pair 3
White & brown = pair 4
White & slate(gray) = pair 5
The color codes were developed by The Bell System in the
early 1940's and I deal with it all the time. Here are some
links that will make it clearer to you.
I connected MY RED to Blue with White
I connected MY Black to White with Orange
I connected MY Yellow to Orange with White
I connected MY Green to White with Blue
It does not work, I even tried to reverse The Red & Green
Still does not work.
How do i wire this for Verizon DSL ?
Do i have to use all 6 Conductor's ?
I called Verizon & they did'nt have the answer for me.
Reversing red and green won't give a dial tone where there is none.
There was a time when it might be necessary to reverse to be able to
dial a touchtone phone, but those days are gone now, at least almost
everywhere. At any rate, no point in trying that until you have a
No point in connecting the yellow or green until you get the dial
tone. Unless you have a very old, unusually connected phone.
But even wrt the red and green, looking at your four lines of text** I
think you've misunderstood prior posters. Blue is for line 1.
Orange is for line 2. Different lines, not different wires from the
same line. 1, 2, 3, and 4 are for different phone numbers, even
though most homes have only one and almost no one has 4.
If red goes to blue and white, green should go to white and blue, or
plain blue or whatever the posts, taken as a whole, say.
Finally, when what you try doesn't work, try other combinations. Say
you have 8 wires. The number of combinations of 8 wires 2 at a time is
8!/2! , 8 factorial divided by 2 factorial = 8*7*6*5*4*3*2/2 = 52,664.
Okay that's a lot but you can cut it down by doing what Mets and
**I wish you wouldn't top post. I had to copy your four lines and put
them below the lines you were relying on, to see the problems. On
usenet, top posting is bad from. I think it's a mistake on email
Find where the wires enter the house, and make sure they are connected
on that end. If you have a network interface box (NIC, aka demarc box),
you can open up the customer side of that and see what colors are in
use. You can also trace the house feed back to where the wires split out
to the various rooms.
If all this sounds like Greek, look in local ad paper for retired or
semi-retired Ma Bell guy who does residential wiring on the side, and
hire them to come by and look at it. Shouldn't cost much if you have all
the wires in place (with no staples through them), and all he has to do
is tone out the line and punch down (or use beenie splices) as needed.
3-pair phone cable got used for a lot of stuff- the wire you found may
have nothing to do with the phone system. More likely, the house was
star-wired, and the unused runs were never connected, or it was
daisy-chained, and previous owner broke a wire in the upstream connector
block. There is a lot of hill-billy 4-color phone wiring in this house,
and it took me a couple hours to get all the outlets working when I
moved in. It was on my to-do list to rewire it all properly, but then I
got DSL on a dedicated pair, and it went way down in priority. At this
point, it will probably be next owner's problem. They all work for
voice, and that is good enough for right now.

Are you certain that the wiring you connected into was itself wired
into the customer demarc box on the side of your house ?
If you wired everything the way you described it above, you are
following the proper color code, you just have to make sure that
the wires you are attaching to are in fact hooked up to something...
As far as wiring for DSL, you need to get your new wire working
for voice first before you even can worry about getting DSL on the
line... Usually where wires are available, DSL would be on a
second pair of lines with a DSL filter installed at the demarc
point and then you would only wire up that DSL pair to be used
as line 1 at the outlet you want to use your modem/router at...
You either need to figure this out on your own or face hiring a
telecom/networking company to handle the issue for you as
the phone company typically doesn't want to get involved in
anything to do with customer premises wiring past the demarc
Well Verizon sends its customers kits, -- and I think even if you hire
them to do it, it would be the same -- which use just one pair for
voice and DSL. It uses filters to keep the DSL stuff out of the voice
part of the system.
With known good house wiring, I might agree. But with typical 'as found'
wiring, especially in an older house, if you have a clear shot to run a
direct wire from demarc to modem location, that is definitely the way to
go. Only need one isolation filter, you don't pick up noise and static
from the other runs, etc, etc. Yes, you can make DSL work with a crappy
wire path, but your odds of not having problems are improved with a
direct run. That is why the contractors do it that way. Wire is cheap,
callbacks are an expensive PITA. Mine is on the house wiring, but on the
second pair, not the dialtone pair. I also have a dry pair all the way
back to the ISP, since my DSL is 3rd-party, because I am outside Ma
Bell's service circle.
It is MUCH better to put the DSL on a separate pair after a
whole house DSL filter...
That way when you start having problems with the DSL you
only have ONE FILTER to check out and replace rather than
one at each phone location using the DSL and voice on the
One of the first things a telecommunications worker learns
Blue, orange, green, brown, slate.
The basic wiring code colours.
From that basis one gets .....................
First pair; Blue + white.
Second pair; Orange + white etc.
Also agree that on the telephone side Green-Red (In North American
practice anyway) is the telephone line where one would normally find
dial tone etc.
It may also be worth mentioning that from a technical point of view
the two wires of each pair are twisted together, each pair at a
different rate, to minimize/avoid interaction between the different
circuits. So it can be important to use the pairs correctly.
I deal with disparate wiring schemes all the time and if I wind
up doing something in a very old house, I'll often find the black-
yellow pair hooked to a low voltage transformer that supplied
power to the lighted dial of a Princess phone from the 50's or
60's. I often recommend replacing the wire if a customer is getting
high speed DSL, by that I mean something in the 3-6 Mbps range.
Some homes have phone wiring dating from the 20's and 30's that's
not good enough for even dialup service. The best performance is
obtained by installing a high quality filter/splitter at the demark
outside of a home or wherever the phone line comes into the building
and running a separate line to the DSL modem. Here's the type I use:
You only seem to know the secondary colors of the 25 pair code...
The primary colors always come first:
White, Red, Black, Yellow, Violet...
The come the secondary colors you refer to:
Blue, Orange, Green, Brown, Slate...
So the correct way to refer to the pairs for the first two lines are:
White with Blue stripe is the tip on the 1st pair,
Blue with White stripe is the ring on the 1st pair...
White with Orange stripe is the tip on the 2nd pair,
Orange with White stripe is the ring on the 2nd pair...
The old residential color scheme was:
Solid Green is the tip on the 1st pair,
Solid Red is the ring on the 1st pair...
Solid Black is the tip on the 2nd pair,
Solid Yellow is the ring on the 2nd pair...
As long as you keep to that scheme and wire the
correct pairs together, you will not have a problem
in the future trouble shooting any work you do now...
Nor will the next guy that ends up buying your house...
The only important thing is to not use the wires
randomly, as it would take a skilled technician
some time to sort out your willy-nilly use of the
wires with a toner and probe to redo it properly...
