In the US, although there are typically four wires in the cable going to the house or business, POTS uses just two of wires (the red and the green), one of which is the "tip" and the other the "ring".
That's the old style cable. Many years ago, they switched to 3 pair CAT 3 cable, with the phone on the blue/white pair. Incidentally, there was a network called StarLAN, which was designed to run on the other 2 pairs of the phone cable. StarLAN became the basis of 10baseT Ethernet. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
