I have two old jacks using a totalof 10 wires from three different cables. One jack connects to one cable with blue, blue/white, white and orange. The other jack connects to two cables one using the black and red only while the other cable has blue, orange, white, and white/slate. The two jacks are jumpered with a white wire. What do I use to get two RJ11 lines from the old configuration.:(

Why do you need Rj11 lines? Are you running the cables a mile or something?

No I have coax two cat5 lines and trying to run RJ11 out of a standard single box.

Ah Ic hmm well that's a tough one then sorry I can't help.

Line 1 Usually Red and Green, or white/blue and blue/white.
Line 2 Usually Yellow and Black or white/orange and orange white.
I understand RJ 11 is standard phone receptacle. When connecting wires to the red and green, you will access line 1 (center 2 pins), for 2nd line, hook to yellow and black for line 2
(outer 2 pins) If you connect line to red and green, and hook up jumpers to red and green of second jack, you will have same number at both jacks.
A volt meter will show active lines. About 48 Volts DC with phone ON Hook.

Cat 5? That would require an RJ45 jack, not RJ11 - this is an 8-wire jack. You should also be using Category 5 rated patch cords (again, eqiupped with RJ45 plugs) and running Category 5 4-pair cable.

I'm not sure if I'm understanding you correctly.

You want to connect some phone jacks with the old wiring style (red/green,yellow/black) to the phone system you have now that uses the new wiring (blue/blue-white,orange/orange-white)?

If so, you just need to run a line from the new wiring to the old wiring.

Blue connects to Red
Blue-White connects to Green
Orange connects to Yellow
Orange-White connects to Black

The red/green/blue is going to be line 1.
Black/yellow/orange is going to be line 2.

Robert, If your place is not wired for Networking, and 3 cables from 3 unknown locations, and with jumper between the 2 jacks, then this is VERY LIKELY:
One of those is coming from outside phone box, may go through other connection(s)first,
The other 2, likely go to 2 other places.
Have to correct above post: White/blue to green and blue/white to red.
Line 2 is still: White/orange to black and Orange/white to yellow.
Ebaines, hope all is well, I usually run 2 cat 5, or cat 5e, 1 for networking, 1 for landlines,
Fax line, and filtered dsl(outside filter, so filters need not hang all over the place. They are all Homerunned, so it is Phone System Ready.

This is the same thing I just said, you're not correcting anything.

You said Blue-White to green. I think you meant white-blue to green, and blue-white to
Red. No problem, I will think of 1 thing, and write another , take care.
Robert, if you have a meter, you will find:

Line 1 white/blue or green +voltage
Blue/white or red - voltage

Line 2 white/orange or black +voltage
Orange/white or yellow -voltage

Neither wire is at ground potential. About 48 volts DC, about 90 volts AC, when ringing.

Ah, I see now. When it's taken out of its surrounding context, you can make it look like I was completely and utterly wrong.

See, what I really meant was the BLUE, connects to the RED. The BLUE and WHITE, connects to the GREEN.

Yes, I know that technically, even though most cat5 cables 1st pair is solid blue, and white with blue tracer, that they are called blue/white and white/blue. Lets just try to confuse the guy who is asking about it by telling him that a blue and white colored wire connects to red, and to green.

I guess I shold correct myself.

The wire that is primarily blue, but which may or may not have a small amount of white or light blue running down it, or small white or light blue rings around it, connects to the wire that is green.
The wire that is primarily white or light blue, but has small amounts of dark blue running down it, or has small rings of dark blue around it.

I have seen it 3 Ways:

1) White/blue to green
Blue/White to red

2) White to green
Blue/white to red

3) White/blue to green
Blue to red

Does make it confusing. That's just 1 pair. Take Care
