BREF INTRODUCTION AND BACKGROUND

ABSTRACT
 The aim of this project is to design and construct a LAN cable tester.  It is a tool for testing LAN cables to find all the problems associated with the cable.  The fault in any of the wire in the cable can easily be detected by the use of this small but useful instrument and the speed can be enhanced very easily which was earlier dumped by the cable fault. .

One of the primary objectives of an Engineer is to endeavour to deliver the best product or the most efficient services at the lowest cost to the end user. Our project was found to meet the expected results. This project uses coding in assembly language to provide a very efficient algorithm for carrying out the required task. The block diagram, the associated technology, algorithms, the software and hardware requirements are all well illustrated to assist good understanding. As of true for most project effort of this nature, progress also contributes after the work. For this reason we devoted a significant effort to the selection of techniques whose value is likely to remain applicable in a rapidly involving body of knowledge. We had immense benefit from this project in that we learned a great deal in the domain of Network Cable Testing which was entirely a new field for us to work and we trust that this project gives contribute in this field. As is true of most writing efforts of this nature, progress continues after the work on the manuscript stop .

For this reason, we devoted significant effort to the selection of the material that we believe is fundamental, and whose values likely to be applicable in a rapidly evolving body of knowledge. Introduction gives an overview about the project. Circuit  The recent technologies used are explained in brief. Moving on to the Diagram and description, Various parts of the project are involved in order to explain various steps taken in project. Description of each block is given in detail to give a clear vision of each step.

 

INTRODUCTION
A cable tester is an electronic device which is used to verify the electrical connections in a cable or other wired assembly. Generally a cable tester consists of a source of electric current, a voltmeter and a switching matrix used to connect the current source and the voltmeter to all of the contact points in a cable. In addition to these parts a cable tester may also have a microcontroller and a display to automate the testing process and display the testing results. A cable tester is used to verify that all of the intended connections exist and that there are no unintended connections in the cable being tested. When an intended connection is missing it is said to be "open" (as in Open circuit). When an unintended connection exists it is said to be a "short" (as in Short circuit). A connection is said to be "miss-wired" if it has two faults: it is open to the correct contact and shorted to an incorrect contact. Generally, the testing is done in two phases. The first phase, called the opens test makes sure each of the intended connections is good. The second phase, called the shorts test makes sure there are no unintended connections. Network Cable Tester is a tool for testing LAN cables, Data communication cables and Tele-communication cables. It finds all problems associated with testing such faults as opens, shorts, cable integrity and it also finds cable length of individual cables or distance to a fault.

DESCRIPTION

One of the most popular experiments that users with multiple PC’s will try is the installation of a home network or LAN. LAN stands for Local Area Network; the correct term applied to any network installed in a limited physical area. In the not-too-distant past, it was common practice to install home LAN’s using coaxial cable, as it was simple to install, readily available, prefabricated in standard lengths and it required no...
