==Applications== Originally, telecommunication circuits transmitted [[analog signal]]s. [[Radio station]]s used them as [[studio transmitter link]]s (STLs) or as [[remote pickup unit]] (RPU) for [[sound reproduction]], sometimes as a backup to other means. Later lines were [[Digital data|digital]], used in pair-gain applications, such as [[carrier system]]s, or in enterprise [[data network]]s. A [[leased line]], ''private circuit'', or ''dedicated circuit'', is a circuit that is dedicated to only one use and is typically not switched at a central office. The opposite is a '''switched circuit''', which can be connected to different paths in a switching center or telephone exchange. [[Plain old telephone service]] (POTS) and [[ISDN]] telephone lines are switched circuits. On certain [[packet switching]] telecommunication circuits, a [[virtual circuit]] may be created, while sharing the physical circuit.
