How do you connect different color phone wires?

I recently ran some 6 conductor phone cable through the house, but couldnt finish the job because I ran out of cable. I need to connect the the new cable I bought to the cable I was already running, but the colours are different. What colours go to what wire?

1st cable:
white - red - blue - black - green - orange

2nd cable:
green - green/white - blue - blue/white - orange - orange/white

Thank you

This page shows the various standards:

You're original wiring (the solid colors) is under "Insulation Solid Color Code" (list #2).

The new wiring is under "Insulation Band-Marked Color Code" (list #1).

Basically match up the numbers to the respective colors:

Red = White/Blue
Green = Blue/White
Black = White/Orange
Yellow = Orange/White
Blue = White/Green
Orange = Green/White

The first color listed is the primary color of the wire, the secondary color is the band or mark (white/blue is mainly white with small blue marks).

Where are you going to splice these together? It would be a good idea to either do it in a junction box at the last jack you could reach or at a mini patch panel. Just in case you have a problem, it's nice to know where to find the ends of the cables.

let me add one more comment as above what he did gave the correct colour pairs

the old colours red / green is line 1 ,, Black/ Yellow is line two ,, bleu / Orange is line 3

those most common colour pairs and please make sure you have it on correct sequnece when you hook up to the phone jack[s]

for two line phone jack the middle two is line one and outer two is line two like this 2,1,1,2 if you look at the jack you will see why i say that this is most common way ditto with 3 line as well but for 4 lines that get tricky i will leave this part out for now due there is 2 or 3 diffrent way to do this

Merci, Marc

"back in the day" the polarity of connection to the telephone ( tip and ring terminals) mattered. Today, although you should try to be consistent, the phone equipment does not care.
