Re: [Equipment] How do i make a phone line cable?
Basically: An RJ11 phone jack uses the center pair for tip & ring of the first line, and the outer pair for tip and ring of the 2nd line.
Newer phones (last ~20 years or so) don't usually care which lead is tip and which lead is ring.
With Telco companies; the rule of thumb is to connect the light colored wires to light colored wires and the dark colored wires to dark colored wires.
So if you are going from the old red and green pair to the blue/white pair, you would connect the red to the white/blue (light colored), and the green to the Blue/white (dark colored).
(line 2) Yellow to White orange, Black to Orange/White.
Back to RJ11 cords.
Because polarity doesn't really matter, and they use the center 2 pins for Line 1 and the outer 2 pins for Line 2;
Let's just say Pin 1 = orange/white, Pin 2 = blue/white, Pin 3 = White/Blue and Pin 4 = White/Orange. 
Now if you can't figure out which pin is Pin 1, then just flip the RJ11 plug around and it will be the first pin to the left, followed by pin 2, pin 3, and pin 4. |
