1. OverviewThe rapid growth of the Internet and the World Wide Web (WWW), and the widespread deployment of personal computers have greatly accelerated the need for higher bit rates, faster local loop connections to the PSTN, and more responsive access to bandwidth on demand. While the picture is not altogether clear at this time, it is certain that new capabilities which are resulting from the current deployments will have significant implications for planners and providers of NS/EP services e.g., the ability to provide real-time video from a disaster site for remote damage assessment or medical diagnosis and treatment. Recent advances in digital signal processing (DSP) have resulted in significant increases in usable bandwidth over traditional wirelines used for PSTN access. However, in many respects, the universal transmission of data on such lines still has significant limitations.
Specific limitations concern achievable data rates, the quality of transmissions, and the availability of shared access.
