5.5.3 and 5.5.4: Table 3-1 describes the WAN connections a telecommunications service provider (TSP) can offer individuals and organizations.

Table 3-1. WAN Connection Types

In addition to the type of connection, consider the following points about specific WAN connections when planning a network:

• Lower-speed, low-cost connections such as dialup and beginning plans for Frame Relay and DSL provide sufficient connectivity for a business that does not host services and that needs only occasional connectivity with smaller downloads.

• Medium- to high-speed connections such as a fractional or full T1 or advanced DSL and Frame Relay plans can provide connectivity for a medium-sized business that plans to host minimal services and occasionally download large amounts of data. In addition, a cable network connection can provide a high-bandwidth solution.
