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:
“I am opposed to writing about the private lives of living authors and psychoanalyzing them while they are alive. Criticism is getting all mixed up with a combination of the Junior F.B.I.- men, discards from Freud and Jung and a sort of Columnist peep- hole and missing laundry list school.... Every young English professor sees gold in them dirty sheets now. Imagine what they can do with the soiled sheets of four legal beds by the same writer and you can see why their tongues are slavering.”
—Ernest Hemingway (1899–1961)
“Somewhere along the line of development we discover who we really are, and then we make our real decision for which we are responsible. Make that decision primarily for yourself because you can never really live anyone else’s life not even your child’s. The influence you exert is through your own life and what you become yourself.”
—Eleanor Roosevelt (1884–1962)
