# The complete Path between two terminals over which one-way or two-way Communications may be provided. See Communications Protocol . # An electronic path between two or more points, capable of providing a number of Channels . # A number of conductors connected together for the purpose of carrying an Electric Current . # An electronic closed-loop path among two or more points used for Signal Transfer . # A number of electrical components, such as resistors, inductances, capacitors, transistors, and Power sources connected together in one or more closed loops.

A dedicated circuit, '''private circuit''', or '''leased line''' is a line that is dedicated to only one use. Originally, this was Analog , and was often used by Radio Station s as a Studio/transmitter Link (STL) or Remote Pickup Unit (RPU) for their Audio , sometimes as a Backup to other means. Later lines were Digital , and used for private Corporate Data Network s. The opposite of a dedicated circuit is a switched circuit, which can be connected to different paths. A POTS or ISDN Telephone line is a switched circuit, because it can connect to any other Telephone Number . On digital lines, a Virtual Circuit can be created to serve either purpose, while Sharing a single physical circuit. |
