ABSTRACT

High-speed access is becoming increasingly popular for

connecting to the Internet and to corporate networks. The

term “high-speed” is generally taken tomean transfer speeds

above the 56 kbps of analog modems, or the 64 to 128 kbps

speeds of Integrated Service Digital Network (ISDN). There

are a number of technologies that provide transfer rates from

256 kbps to 1.544 Mbps and beyond. Some offer asymme-

trical uplink and downlink speeds that may go as high as

6 Mbps. These high-speed access methods include DSL,

cable modems, and wireless point-to-multipoint access.
