Asymmetrical Digital Subscriber Line
Asymmetrical Digital Subscriber Line – Bellcore’s term for one-way T-1 to the home over the plain old, single twisted pair wiring already going to homes. ADSL is designed to carry video to the home. ADSL, like ISDN, uses adaptive digital filtering, which is a way of adjusting itself to overcome noise and other problems on the line. According to Northern Telecom, initial ADSL field trails and business cases have focused on ADSL’s potential for video on Demand service, in competition with cable pay-per-view and neighborhood video rental stores. But ADSL offers a wide range of other applications, including education and health care. Once telephone companies are able to deliver megabits to the home, Northern Telecom expects an explosion in potential applications including work-at-home access to corporate LANs, interactive services such as home shopping and home banking and even multi-party video gaming, interactive travelogues, and remote medical diagnosis. Multimedia retrieval will also become possible, enabling the home user to browse through libraries of text, audio, and image data – or simply subscribe to CD-quality music services. In the field of education, ADSL could make it possible to provide a low-cost “scholar’s workstation” – little more than a keyboard, mouse and screen – to every student, providing access to unlimited computer processing resources from their home. For a more modern version of ADSL, see DMT, which stands for Discrete Multi-Tone.
