Question by countrygirl: wiring second phone line a certain way….need help?
I have a regular phone line and a computer with internet dsl and modem hooked up in the living room
I just got a second phone line hooked up for our spare bedroom with a separate phone number.
However, I know normally you would hook up the yellow and black for the second line to work, but the phone repair guy that came to hook it up outside, said that i have to hook up the red and green or red and black or something otherwise it won’t work. I don’t understand why …something like because there is not a splitter or something, i don’t know . i tried every combination and get nothing. when i hook up the red and green to red and green , yeah i get a dial tone but then it is only working once again for my regular phone line?
what is the problem or what do i do?

Depending on the age of the structure and your country, the standard may be different. Dial tone is distributed on the same colors as a modular jack: Green and Red is the first line (or the blue/white pair), Black and Yellow is the second line (or the Orange/white pair) and Blue and White (or the green/white pair) is used for line 3. That’s how we wire them, but it doesn’t prevent some idiot from changing or inventing a different color code. Amateur electricians and DIY’ers are good for splitting up paired cables “because the Green wire and the Orange wire are close to red and green”.
The second thing you have working against you is a lot of people will daisy chain the cables between jacks in the house, and “since a phone only needs one pair, I’ll just hook up one pair.” Oops, now the second pair is cut or not spliced behind a jack somewhere.
A telecom person with a toner and probe can usually trace out the wiring on a house, or you might get lucky and just wire the black and yellow wires to the second line and open up each jack in the path or randomly to see if you get dial tone on the second pair and find the open connection. An inexpensive toner and probe is available at the big box home improvement stores (made by Ideal) for about $ 40. You might grab a 2-line splitter (looks like a “T” adapter with L1 on one side and L2 on the other) to help you in troubleshooting. At the outside interface, the cable feeding into the house will, or better be, more than 2 wires. connect the second pair of wires to the second line, then go to the jack closes to the interface box, plug in your splitter, and see if you have dial tone for line 2 on the L2 jack. Then you just keep working around the house until you get dial tone in the spare bedroom.
