My landline phone quit working this weekend. I knew I'd not get repair service until Monday. I opened the connection box outside and found a broken wire. Then another one broke while I was working in there. So I took off all the wires, restripped them all, and started over with "fresh" wires. The source wires are both black. and I had them off the main connection box outside. I did not label them (probably should have).
How do you know which source wire should go to the red and which should go to the green (on the house wires)? I put these colored ones to the same screws that they were originally, but I could have reversed the black (source) wires....
Or dont it matter?????
The phones do work, and so does my internet, so either I guessed right, or it works either way !
