Internet Leased Line

A leased line is a private bidirectional or  symmetric telecommunications circuit  between two or more locations provided  in exchange. An Internet leased line is a premium  internet connectivity product, normally  delivered over fiber, which provides  uncontested, symmetrical speeds with  full duplex. It is also known as an  Ethernet leased line, dedicated line, data  circuit or private line.

As demand grew on data network telcos  started to build more advanced networks  using packet switching on top of their  infrastructure. Thus, a number of  telecommunication companies added  ATM, Frame-relay or ISDN offerings to  their services portfolio. Leased lines were  used to connect the customer site to the  telco network access point.
