Some Further Analysis on Scramblers for FDDI on Shielded Twisted Pair and Data Grade Cable
Author: Michael P. Spratt
Publisher:
ISBN:
Category : Fiber Distributed Data Interface (Computer network standard)
Languages : en
Pages : 10
Book Description
Abstract: "The Fiber Distributed Data Interface (FDDI) was originally designed as a fiber optic Local Area Network. Recently, attempts have been made to transmit FDDI over copper cables, reducing costs. HPLB was part of a consortium of companies looking at the transmission of FDDI over Category 3 (voice-Grade) unshielded twisted pair cable. In the operation of the FDDI Media Access Control protocol, long sequences of the Idle symbol will occur, and to reduce radio frequency emission, the use of scrambling is required. This paper was presented to the February 1992 meeting of the FDDI committee in Austin, Texas, and further explores the scrambler systems and mathematics describing them, introduced in 'The Use of Scramblers with an Anti-Locking Circuit', first presented at the December 1991 meeting of FDDI. In this paper, the further issues covered are: the locking of the scrambler by FDDI line states other than Idle, (or indeed any repeating input data pattern), the use of an Anti-Locking Circuit at the descrambler at the receiver, as well as at the scrambler, and the limit on the number of transition-free code bits generated by the transmitter system."

Category : Technology & Engineering
Languages : en
Pages : 242
Book Description
Please note this is a Short Discount publication. Fiber Distributed Data Interface [FDDI] is the American National Standard Institute's proposed standard for a 100 Mbps token–passing ring using an optical fibre medium. The FDDI standard has become a focal point for optical technology application in the LAN environment. The market place is filling with products in every category from complete systems to optical transceivers. The 1990s see FDDI as the predominant high speed LAN and backbone. The latest edition of this report is thoroughly updated and gives a complete overview of FDDI technology and products as they exist at the date of this report.

This paper was presented to the December 1991 meeting of FDDI in San Diego. It discusses error propagation, which occurs in the decoding of line codes and in descrambling of self-synchronized scramblers. It describes the locking of scramblers and an Anti-Locking Circuit. It discusses the advantages of using primitive polynomials with even numbers of taps to implement the scrambler, and proposes a suitable trinomial."

The Informatics Handbook
Author: S.A. Fist
Publisher: Springer Science & Business Media
ISBN: 1461520932
Category : Technology & Engineering
Languages : en
Pages : 752
Book Description
This is not a dictionary - and nor is it an encyclopedia. It is a reference and compendium of useful information about the converging worlds of computers, communications, telecommunications and broadcasting. You could refer to it as a guide for the Information Super Highway, but this would be pretentious. It aims to cover most of the more important terms and concepts in the developing discipline of Informatics - which, in my definition, includes the major converging technologies, and the associated social and cultural issues. Unlike a dictionary, this handbook makes no attempt to be 'prescriptive' in its definitions. Many of the words we use today in computing and communications only vaguely reflect their originations. And with such rapid change, older terms are often taken, twisted, inverted, and mangled, to the point where any attempt by me to lay down laws of meaning, would be meaningless. The information here is 'descriptive' - I am concerned with usage only. This book therefore contains keywords and explanations which have been culled from the current literature - from technical magazines, newspapers, the Internet, forums, etc. This is the living language as it is being used today - not a historical artifact of 1950s computer science.

Pages : 733
Book Description
The physical linkages responsible for carrying a company's data continue to be the most neglected components of the typical network—to the extent that nearly 70% of all network-related problems result from poor cabling. In this third edition of a widely acclaimed resource, three networking experts share their extensive experience, teaching you the cabling skills you need to build a reliable, efficient, and cost-effective network cabling infrastructure. As you master these techniques, you'll learn to avoid common pitfalls and troubleshoot problems as quickly as they arise. Coverage includes: Choosing the right cables and components for your network architecture and topology Avoiding unnecessary and unexpected costs Understanding the current limitations of data communications and network cabling Understanding how laws and building codes constrain cabling Understanding the function and importance of universal cabling standards Determining when you have a cabling-related network problem Assembling a complete cabling toolkit Integrating voice and data on the same cable system Setting up an infrastructure in which desktops, printers, copiers, and other nodes share cabling Understanding issues of bandwidth, impedance, resistance, attenuation, crosstalk, capacitance, propagation, delay, and delay skew Working effectively with USB and Firewire Knowing when to discard legacy cabling and begin anew Documenting your cabling Creating an RFP and selecting a vendor
