Digital subscriber line modems equalize response of line (channel) to fight with interferences and line dispersion which down the bit-rate of transmission. Main equalization principle is “Channel shortening” which is the base for time domain equalizers (TEQ). Many TEQ algorithms have been already proposed, mainly in theoretical sense. With growth of hardware performance, more complex methods ca...

We report results from the analysis of a 24-hour packet trace containing aggregate TCP traffic of approximately 1300 residential ADSL clients. We make observations similar to earlier studies by the research community: the major fraction of the total traffic originates from P2P applications and small fractions of connections and clients are responsible for the vast majority of the traffic. Howev...

This document defines a Management Information Base (MIB) module for use with network management protocols in the Internet community. In particular, it describes objects used for managing parameters of the "Asymmetric Digital Subscriber Line" family of interface types: ADSL, ADSL2, ADSL2+, and their variants. Morgenstern, et al. Standards Track [Page 1] RFC 4706 ADSL2-LINE MIB November 2006

This paper concerns the design and development of an Application Specific Integrated Circuit (ASIC) for the implementation of the Transmission Convergence sub-layer of the xDSL protocols. The work presents the required functionalities and focalizes on the hardware and software architecture of the module. Key-Words: ADSL, VDSL, G.Lite, xDSL, ATM, Transmission Convergence sub-layer, ASIC

The growing demand to transmit high-speed digital data in many local area networks (LAN ’s ) and digital subscriber lines (DSL’s) has resulted in a wide variety of transmission systems that have to co-exist on twisted wire copper pairs. In this paper, we address the problem of maintaining speehvnz compatibility between various services that may use Merent transmission technologies, by shaping i...

Boar semen is usually collected by the gloved hand method, allowing possibilities for bacterial contamination during the collection process as well as during the subsequent processing of the semen. Bacteria such as Staphylococcus and Streptococcus spp., are found on the skin and mucosa of health animals as well as in the gut (e.g. enteric bacteria) and respiratory tract [1]. Personnel also repr...

ACKNOWLEDGEMENTS There are a number of people that should be recognized for their help and assistance during my thesis work. First of all I want to express my sincere gratitude to my thesis advisor professor Martin A. Brooke, who has given me the opportunity to complete my Ph.D. study at school of Electrical and Computer Engineering in Georgia Institute of Technology. I really appreciate the ti...
