The benefits of frame relay technology include relatively low cost of ownership, flexibility and stability. The downside is that few general support technicians understand how it works and or how to troubleshoot it if something goes wrong. Using traditional copper telephone lines, DSL uses a compression process that allows it to push data over lines at speeds ranging from 128 kbps to 1.5 megabytes per second. Performance is excellent with DSL, but DSL is available in only a limited number of areas. Many well-known providers are experiencing major downfalls in providing DSL service.
Installation time can take weeks or months, and user support can be inconsistent or minimal.
Many nonprofits cannot afford the basic monthly charge just for the line rental, which is different from the actual monthly cost. They also are stable. You can purchase fractions of the speed at much lower rates. Purchasing fractional lines means you will share the bandwidth with others and also the cost. The downside is cost, pure and simple.
