High-speed modems and standards have been developed to meet the user demands for high-speed data information and faster communications with the Internet. DSL modems have been successful in reaching a large population because of the low cost structure, reliability, and high-speed data rates. ADSL and versions of ADSL, such as G.lite addressed a need in the market for many users. Hybrids using ISDN and ADSL have been produced, and high speed DSL such as HDSL and VDSL are reaching even greater modem speeds. Cable modems are rapidly becoming a solution for high-speed information to the home and office. Many new standards for bringing voice, data, and video to the home are being established as higher speeds and the number of users continue to grow.
