I've searched and found many sites the list several color combinations of phone jack wires but, none of them match our colors. We have solid colors; light orange and dark orange twisted together; light brown and dark brown twisted together; ligt blue and dark blue twisted together and light green and dark green twisted together. I want to hook the wires up to a phone jack and the ones I've bought have the stander red, green, yellow and black wires in them. How do I match my wires up with the phone jack?

The blue pair is line 1.

Thank you for the response; but, we are signed up for a second line for
our fax. Which color pairs go together?

It's in the link.

T1 what w/blue GRN
R1 blu w/wht RED

T2 what w/or BLK
R2 or w/wht YEL

T and R are Tip and Ring. The 1 and 2 are pair 1 and pair 2 which is typically line 1 and line 2.

With two lines, the simplest way is to wire all the jacks in the fashion above. When it comes to connecting the FAX machine, buy a little adapter. I believe available from Radio Shack which will take a single plug and separate it into Line1+line2, line1 and Line2.
Use the line2 port for the Fax machine. The line1+line2 port is used for 2 line phones.

Since you are "modernized", there are other ways of dealing with the distribution of telephone from using jacks that use 3 pairs which the standard telephone plug is, but usually only 4 have connections or using jacks that contain all 4 pairs. If you pick the right jack, the 6 pin plugs will plug in. Also the color codes that you have will be in the jack.

Since this is a new home and I do not know how many jacks have been wired or how they have been wired. Generally 2 CAT5 cables, and 2 Coax cables are the minimum for each location. There is a special siamese cable that can be used for this. One even contains fiber.

These runs should terminate in a central location and the term is "structured wiring". That location typically has a panel and a bunch of modules that can be used to connect these cables as you see fit.

Another way is to use "patch" panels. In this case there would be three.

1. would be all telephone and all jacks would be bridged together.
2. would go to the outlets in the house which would be appropriately labeled RJ45 (8 pin)
3. Could be a nearby Ethernet switch.

The patch cable can be CAREFULLY made and marked to distribute the lines. Initially, you could by 1' patch cables and distribute all lines everywhere. The 8 pin jacks should be designed to accept the 6 pin telephone plug.

The telephone set, shoul also include an RJ31x jack for a future alarm system. This jack makes the telephone system normal when unplugged. When plugged in, the alarm system can seize the line.

If your planning a DSL installation, it's best to put the filter on the NID outside the house.
