    Due to increased pressure from alternatives, the pace of xDSL deployment must accelerate. This acceleration places increased emphasis on copper loop prequalification, which determines the suitability of a given loop for some class of xDSL service, and turn-up verification, which verifies that the customer is receiving the service tariffed or contracted. Although the physical characteristics and el... View full abstract»

    The objective of this article is to present the end-to-end broadband service and protocol architecture over DSL that has been adopted for both ADSL and G.Lite (PPP over ATM). G.Lite is a new form of DSL, and its characteristics are discussed. The article then presents a vision for the evolution of an analog modem-based service to G.Lite and ADSL services. The article explains the standardized arch... View full abstract»

    The voice-grade telephone channel is the communication medium most widely available throughout the world. Its limitations, a relatively narrow bandwidth and a moderate SNR figure, have challenged telecommunication researchers and engineers over several decades to develop technologies able to pass higher and higher data rates. The sophisticated combination of trellis coding and quadrature amplitude... View full abstract»

    Modern telecommunications systems are becoming increasingly complex, in both their internal construction and the degree of interconnectivity-and interdependence-between systems. This situation is exacerbated by regulatory demands for operator interworking and requirements for high-quality delivery to users. In this context, the crucial issue is the ability of systems to retain their operational st... View full abstract»

    NTT is aggressively promoting the deployment of fiber to the home in Japan in order to deploy broadband services. The demand for high-speed Internet access has been increasing rapidly. Until migration from metallic cables to optical fiber is complete, NTT needs to develop technology that can provide high-speed access over the existing metallic cable. We believe that high-speed subscriber transmiss... View full abstract»
