Have RD and WHT, BLU and WHT, BRN and WHT, and GRN and WHT wires from line. The new jack has yellow, green, red, and black. What wires go where? HELP!

 

[nap]

depends what you connected on the other end. In most houses that have a single line, the blue blue/white is used on the green and red terminals.
whatever you use, you have to be sure you use the same wires on each end.

Blue/white on Red, white/blue on green.

Blue/white on Red, white/blue on green.

there is no blue/white. You have blue and it's mate white with blue trace. Out of a bad habit, I always call them <color>/ <color/white> instead of <white/<color>

 

[zpm]

Untrue.

For the standard 4 pair cable found in most homes, blue and white/blue is close enough.

When you get into real phone wiring with cables of more than 5 pairs, there's a group/pair color system.

The ring wire will have the pair color (blue,orange,green,brown,slate) as the major color and the group color (white,red,black,yellow,violet) as the minor color, i.e. mostly blue with a white trace. On the corresponding tip wire, the group color will be the major color and the pair color will be the minor color, i.e mostly white with a blue trace. blue/white + white/blue are pair 1 of group 1, blue/red + red/blue are pair 1 of group 2.

ya, I'm pretty familiar with the color scheme. blue, orange, green, brown, slate (all in the white group), they you repeat and replace the white with red, then you repeat and replace the red with black, then yellow, then violet


that gives you 25 pair. Then you start bundling them in groups of 25 pair with a binder. You want me to keep going? binder colors/ blue/white, orange/white, green/white, brown/white, slate/ white (and on through the same color scheme as the pair colors up through 600 pair. You want me to get into group binders too?

I've been doing this for a few years and have yet to run across a blue/white wire. The pair first color has been a solid color on every one of the thousands of terminations I have made.
Do you have some cat5 cat5e, cat6 or cat6a with a blue with a group color trace in it? It might be out there somewhere but I've yet to see it.

 

[Jim Port]

All the CAT5 I have run has always had a blue with a white trace and a white with a blue trace. This continued for the other pairs ie O/w and W/o etc.

I'm currently holding a piece of cat5e manufacturer/ Superior Essex

I'm not seeing a bit o' white in the ring color.

got a brand that uses a tip color trace in the ring color? I'm open to being educated but if somebody is going to educate me, you're going to have to support the claim.

In the good old days, the number one wire was white and the #2 wire was colored.
To indicate a pair, the white and the main color were twisted.

So, the first pair will be the white and blue twisted together. The second pair is white and orange(red?) twisted together. Number 3 is white and green and 4 is white and brown.
Usually convention would have dial tone on the w/bl pair. These would connect to the grn and red on the jack. The polarity doesn't matter.

Nap, most wire mfg. use blue with white, and white with blue. You have found the oddity.

feel free to post a manucfacturer. While I happened to reach over to the shelf and grab a piece of the cable I did, it isn't the only cable I have ever worked with.

Raygo (no idea who the are, just nabbed it from a retailers pic)

henan kosan

something from a Dell site, I think it is Belkin

so far, 4 for 4 do not have a tip color trace in the ring color. Anytime you guys find something different, feel free to pop on in.

Please stop me by showing me a cable with a tip color trace in a ring color.

here's a real close up of somebody's cable.

still not seeing a tip color trace in the ring color. Are my eyes that bad that I can't see that trace in there you all claim is there?

Maining (a Chinese manufacture)

I can go on forever, at least it looks that way.

So, there is 6 and the one in my hand makes 7. Still believe I have the oddity?

So, post up 1 that is colored like you say they all are. Just one.

 

[Jim Port]

Darn it NAP, I looked at the box in my truck and it is blue and white/blue.

I did find these images to support my post.

I just found an ICC brand keystone that also shows Bl/W and W/Bl etc as the conductor colors.

I won't deny that it is sometimes referred to as blue/white and white/blue. I have seen it used before. My point is regardless of that, I have not seen any cable that was actually colored like that and since this all started with describing to a layman what wires need to be connected to what terminal, I argue that the proper description was blue- blue/white. Heck, the guy might still be looking for a blue/white wire and unless his cable is colored like that, never find it.:laughing:


while I admit I could be wrong, I stick by my statement that I have never seen a cable with a blue/white-white/blue pair.

maybe zpm can provide a manufacturer that uses that color system.

Comtran Cat3. Its on the Home Depot web site. Pretty obvious there's white (group color) traces on the ring wires. No idea if it would actually come like this. Don't think its common any more (since its cheaper to not add the white), but it was typical many years ago. I kind of remember making up patch cables back in the 80's and those cables had blue/white. Of course that was the 80's and that's a decade best left forgotten.

Well now you've seen it and your life is complete.

ZPM, I'm glad you found it. It's been many years since I worked with it so I started to wonder if it wasn't my memory confusing Cat wire with the 25 pair I'd encountered. Anyway glad to see I'm not crazy.....at least not yet.

even though it doesn't fulfill the challenge, I'll give it to ya.

from my previous post:

Do you have some cat5 cat5e, cat6 or cat6a with a blue with a group color trace in it? It might be out there somewhere but I've yet to see it.
