  • How many wires are in a phone line?


    Four wires
    -----------------

    In a typical home, the telephone cables connecting your phones within you home contain four wires. red, green, yellow and black. They are used in pairs for each phone line you have.

    There might be 4 but a phone only uses/needs two.
    The line from the pole to the house is usually 2 wire.
