Private line
From Wikipedia, the free encyclopedia
This article is about the telephony concept. For the Finnish rock act, see Private Line.
In 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.
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.
