Abstract

A VDSL based broadband data communication network system is provided that utilizes ATM/IP all the way to an end user PC, thereby allowing selectable bit rate delivery to the end users, with a Class of Service (COS) and Quality of Service (QOS) selection. A headend is connected to external Internet service providers and a network central office, and is arranged to receive and send multi-protocol signals to the Internet service provider, and receive and send ATM signals to the central office. This VDSL data architecture is very functional and flexible with the capability of supporting such services as streaming video and audio, voice over IP, digital advertisements, videoconferencing, gaming, business-to-business service, E-commerce, video-on-demand, and interactive TV. The VDSL data network will support very high-speed two-way data services over fiber optics using SONET, Dense Wavelength Division Multiplexing, IP, ATM, and other transport systems. Furthermore, the VDSL data architecture also supports very high-bandwidth multimedia interactive applications for delivery to businesses, homes, or Multiple Dwelling Units using either Fiber-to-the-Node (FTTN), Fiber-to-the-Curb (or Neighborhood) (FTTC), and Fiber-to-the-Home (FTTH) using VDSL technology.
