I need to terminate several phone lines at my brothers. They are all 4-pin ends. I don’t know the order or the wires. My house was all 8-pin connections, I didn’t know if it was the center four of the 8-pin order or different. COuld someone give me the order holding the connector with the tab down? I thought someone once told me it’s the orange and orange/white that brings the dial tone in.
Thanks
Roy

This really depends on who does the wiring.
I've seen red/green as the first pair on older wiring
A lot of phone companies use blue blue/white as #1
Some use Orange Orange/White
Easiest way I can tell you is just examine where it is coming from, and how it is hooked up. Use a tone generator, and a tone finder.
The best I can put it is don't assume that the person before you did it all the typical way.
I'm not sure if I understand, or are going to answer it properly. Red Green is one line, Black Yellow is traditionally second line. If you're talking about cat5 cable with the pairs of blue, green, orange and brown, Typically the blue/bluewhite is the primary line, and it occupies the center two pins on an rj-11 jack. Does that help?
If you're referring to the colors of the wires coming from the telco, i'm not sure i can help you there.

Thanks Neil,
That's what I neededRoy
white/blue
blue/white first pair
white/orange
orange/white second pair
white/green
green/white third pair
white/brown
brown/white fourth pair
white/slate
slate/white fifth pair
The colors are for telco only. They change some what for network
My local phone co. mounts small boxes, usuaully outside, where the line comes in. It's called an interface, and if you open the "customer" side you can probably identify the colors your phone company is using.
If he only has one line, the phone co usually uses blue/white with blue.
The wire colors will be determined by the existing wiring in the house. It it's phone wire, it'll have Red/Green(pair 1), Yellow Black(pair 2) and Blue/White(pair 3). Cat 5 will be Blue/White w/Blue(pair 1), pairs 2 and 3 will be determined by which wiring standard is used, pair 4 is Brown/White w/ Brown.
Not Orange/Orange w/White. Blue/White w/Blue is the pair used for a one line connection, typically.
Hope this helps:
