Phone Wiring FREE cabling and networking Helpdesk

 Phone Wiring
I have 2 phone lines and would like to access both from one outlet. When I removed the face plate on that outlet I see only 4 wires (1 each - red, yellow, green, black). I tried hooking up to a dual modular wall jack but can only get one line to work. Do I need 4 pair of lines instead of 2 to make this work ?

Dear Pete,

The pair split should be supported at both ends of this line. So, if you take red-green to one jack and yellow-black to the other, the wiring block at the other side of the cable should be connected the same way. If this is about just regular analog dial tone, you should be fine with 1 pair per jack.
