Private Line

In wired telephony, a private line or tie line is a service that involves dedicated circuits, private switching arrangements, and/or predefined transmission paths, whether virtual or physical, which provide communications between specific locations. Most private lines connect only two locations though they may be switched at either end or both. Some have multiple drop points.

Note: Among subscribers to the public switched telephone network(s), the term "private line" is often used to mean a one-party switched telephone line, as opposed to a party line.

Famous quotes containing the words private and/or line:

    All significant truths are private truths. As they become public they cease to become truths; they become facts, or at best, part of the public character; or at worst, catchwords.
    —T.S. (Thomas Stearns)

    The modern picture of The Artist began to form: The poor, but free spirit, plebeian but aspiring only to be classless, to cut himself forever free from the bonds of the greedy bourgeoisie, to be whatever the fat burghers feared most, to cross the line wherever they drew it, to look at the world in a way they couldn’t see, to be high, live low, stay young forever—in short, to be the bohemian.
    Tom Wolfe (b. 1931)
