A series of networking tutorials focused on Ethernet technology.

A brief list of acronyms used in the Ethernet, Fast Ethernet, Gigabit Ethernet, 10Gigabit Ethernet and Power over Ethernet consortia.

The purpose of this article is to discuss the concept of Bit Error Ratio testing, and will explain, using a minimum amount of math, the answer to the fairly common question: "How many bits do I need to send in order to verify that a devices exceeds a given BER?"

This is an all encompassing overview of Ethernet technologies, from 10Meg to 10Gig and how it all works.

Originally presented at the 2001 Network+Interop even in Atlanta.

The presence of crosstalk is a major detriment to the performance of Digital Subscriber Line (DSL) transceivers. It is therefore important to test performance under a wide variety of crosstalk scenarios. This thesis presents the development of a crosstalk noise generation system as a tool for DSL performance testing. Where many commercially available solutions are limited to specific testing needs, the system presented here is universal and can simulate virtually any noise scenario conceivable for DSL deployment.
Several requirements for the accurate frequency domain modeling of DSL crosstalk are presented. The time domain properties of crosstalk were also studied with particular attention paid to the amplitude distribution. The importance of a Gaussian amplitude distribution and the limiting effect of a finite-length pseudo-random crosstalk sequence on the "tail" of the Gaussian distribution were investigated. A method of forcing finite-length crosstalk sequences to have a "near-Gaussian" amplitude distribution is proposed.
