I was assigned the duty of running multiple phone lines with one cable. We use Avaya MLX-10DP phones that connect with CAT 3 cables. My question is which lines in the cable(green, orange, blue or brown) must I split in order to run two phone lines to the receiving end in the office? Thanks in advanced.

A cat5 has 4 twisted pairs,

The standard is
Orange / Orange White
Green / Green White
Blue / Blue White
Brown / Brown White

The key concept is to make sure you line up on both side..if you choose to use the orange pair make sure you use the orange pair on the other end.

I hope I understood your question..

So if you where to use the Blue/White pair for one Phone Line and the Green/White Pair for the other that would give you 2 Phone Lines with the option for 2 more out of a CAT5 Cable.
