Lease-Line WAN

Multiple LANs are connected with the help of a WAN using a device called a Router.

  • One of the types of WAN is Leased Line WAN.

  • The Company using the leased line pays a monthly lease fee to the Telco (Telephone) Company who created the leased line by installing a large network of cables and specialized switching devices to create its own computer network.

  • To connect two different LANs a Router is placed on each site with each Router connecting one port to its Native LAN & another to the WAN.

  • Leased-Line WAN uses a Full-Duplex logic which is connected via 2 Pairs of Wires (4 Wires), One Pair for each direction.

  • The service acts like a Long crossover cable between two points, but physically A Leased Line is not one long Crossover cable rather it is a Network with multiple devices created by a Telco Company.

  • A leased Line is also known as a leased circuit, Circuit, Serial link, Serial line, Point-to-point link, Point-to-point line, T1, WAN link, Link, Private line
