ABSTRACT
High-speed access is becoming increasingly popular for connecting to the Internet and to corporate networks. The term “high-speed” is generally taken to mean transfer speeds above the 56 kbps of analog modems, or the 64 to 128 kbps speeds of ISDN. There are a number of technologies that provide transfer rates from 256 kbps to 1.544 Mbps and beyond. Some offer asymmetrical uplink and downlink speeds that may go as high as 6 Mbps. These high-speed access methods include DSL, cable modems, and wireless pointto-multipoint access.
