leased line - Definition from the Hotspot Shield Glossary
A leased line is a specially created telephone line that is setup by a telecommunications provider - The line is permanent until terminated by the business and usually they are used by large businesses that require regular communication between offices in different regions or countries. Leased-lines have a permanent connection that is always active, whereas older dial-up connections are only active when the user is dialed in. Leased lines provide much faster connection and transfer speeds compared to dial-up connections, and also as the line is private, there will be no disruptions or degradation of quality; with these benefits comes an increased cost. The cost will be affected by the speed of the line and the distance the line is travelling.
