ITU-T G.994.1 (G.hs) Handshake Procedures for DSL Transceivers Lincoln Lavoie (UNH-IOL)

This presentation provides an overview the ITU-T G.994.1 (G.hs) Handshaking Procedures for Digital Subscriber Line Transceivers standard. The overview covers the physical layer modulation (DPSK), frame structures, message structures, and parameter encoding. The presentation also includes examples of the differential encoding used for the modulation, and the delimiting bits used within the parameter tree.

ADSL Tutorial Matthew Langlois (UNH-IOL)

This tutorial provides an overview of ADSL technology and focuses on the physical layer as defined in ANSI T1.413-1998. From the introduction: "The demand for high-speed data networks in the "last mile" has driven the need for robust, interoperable, and easy to use multi-vendor Digital Subscriber Line (DSL) access solutions. DSL collectively refers to a group of technologies that utilize the unused bandwidth in the existing copper access network to deliver high-speed data services from the distribution center, or central office, to the end user. DSL technology is attractive because it requires little to no upgrading of the existing copper infrastructure that connects nearly all populated locations in the world. In addition, DSL is inherently secure due to its point-to-point nature."

Digital Communications John G. Proakis

From the preface: "The third edition of Digital Communications has undergone a major reorganization. Compared with with the second edition, which had eight chapters, the third edition contains fifteen. Chapter 1 (Introduction) and Chapter 15 (Multiuser Communications) are new. Other new material that has been added includes a treatment of run-length-limited codes, Nakagami fading statistics, trellis codeing for fading channels, multicarrier modulation, and an expanded treatment of blind equalization. Since this is an introductory-level text, the treatment fo these topics is limited in scope. Some topics that were in the second edition have been deleted, including echo cancellation and suppression of narrowband interference in spread spectrum signals."
