Simplicity: Point-to-point communication links require minimal expertise to install and maintain.Ĭost: Point-to-point links are generally the most expensive type of WAN access. Table 1-1 Advantages/Disadvantages of Leased Lines Advantages Table 1-1 describes the advantages and disadvantages of using leased lines. Optical carrier (OC) transmission rates are used to define the digital transmitting capacity of a fiber-optic network. For instance, a T1 link supports 1.544 Mb/s, an E1 supports 2.048 Mb/s, a T3 supports 43.7 Mb/s, and an E3 connection supports 34.368 Mb/s. In North America, service providers use the T-carrier system to define the digital transmission capability of a serial copper media link, while Europe uses the E-carrier system, as shown in Figure 1-21. Leased lines are available in different capacities and are generally priced based on the bandwidth required and the distance between the two connected points. The term leased line refers to the fact that the organization pays a monthly lease fee to a service provider to use the line. Leased lines have existed since the early 1950s for this reason, they are referred to by different names such as leased circuits, serial link, serial line, point-to-point link, and T1/E1 or T3/ E3 lines. Point-to-point lines are usually leased from a service provider and are called leased lines. When permanent dedicated connections are required, a point-to-point link is used to provide a pre-established WAN communications path from the customer premises to the provider network. In this topic, you compare private WAN technologies. Refer to the online course to complete this activity.
