New York • San Francisco • Washington, DC. Auckland • BogotA • Cara- cas • Lisbon • London Madrid • Mexico City • Milan • Montreal • New Delhi San Juan • Singapore • Sydney • Tokyo • Toronto 2 PREFACE The motive of this book is to expose practicing telephone engineers and other graduate engineers to the art of digital switching system (DSS) analysis. The concept of applying system analysis techniques to the digital switching sys- tems as discussed in this book evolved during the divestiture period of the Bell Operating Companies (BOCs) from AT&T. Bell Communications Research, Inc. (Bellcore), formed in 1984 as a research and engineering company support- ing the BOCs, now known as the seven Regional Bell Operating Companies (RBOCs), conducted analysis of digital switching system products to ascertain compatibility with the network. Since then Bellcore has evolved into a global provider of communications software, engineering, and consulting services. The author has primarily depended on his field experience in writing this book and has extensively used engineering and various symposium publications and advice from many subject matter experts at Bellcore. This book is divided into six basic categories. Chapters 1, 2, 3, and 4 cover digital switching system hardware, and Chaps. 5 and 6 cover software ar- chitectures and their impact on switching system reliability. Chapter 7 primarily covers field aspects of digital switching systems, i.e., system testing and accep- tance and system maintenance and support. Chapter 8 covers networked aspects of the digital switching system, including STf SCP, and AIN.

  • Telecom) Terms Glossary and Dictionary - A
    Tele-Communication (Telecom) Terms Glossary and Dictionary - A A & B Bit A & B Bit is used in digital environments to convey signaling information. A bit equal to one generally corresponds to loop current flowing in an analog environment; A bit value of zero corresponds to no loop Current, i.e. to no connection. Other signals are made by changing bit values: for example, a flash-hook is sent by briefly setting the A bit to zero. A Links A Links, also known as SS7 access links, connect an end office or signal point to a mated pair of signal transfer points. They may also connect signal transfer points and signal control points at the regional level with the A-links assigned in a quad arrangement. A&B Bit Signaling A&B Bit Signaling, also called 24th channel signaling, is a procedure used in T1 transmission facilities in which each of the 24Â T1 subchannels devotes 1 bit of every sixth frame to the carrying of supervisory signaling information. On T1 lines that use Extended SuperFrame(ESF) framing, the signaling bits are robbed from the 6th, 12th, 18th, and 24th frame, resulting in "ABCD" signaling bits. ABAM cable ABAM cable refers to a type of T1 cable. This cable was a 22 gauge, 100 ohm insulated, twisted pair. ABAM cable is no longer available, but you can easily find cable that meets the technical requirements. Abandoned Call Abandoned Call is a call in which the call originator disconnects or cancels the call after a connection has been made, but before the call is established.

  • Software Fault Prevention by Language Choice: Why C Is Not My Favorite Language
    Software Fault Prevention by Language Choice: Why C is Not My Favorite Language Richard Fateman Computer Science Division Electrical Engineering and Computer Sciences Dept. University of California, Berkeley June 15, 1999 Abstract How much does the choice of a programming language in¯uence the prevalence of bugs in the resulting code? It seems obvious that at the level at which individuals write new programs, a change of language can eliminate whole classes of errors, or make them possible. With few exceptions, recent literature on the engineering of large software systems seems to neglect language choice as a factor in overall quality metrics. As a point of comparison we review some interesting recent work which implicitly assumesa program must be written in C. We speculate on how reliability might be affected by changing the language, in particular if we were to use ANSI Common Lisp. 1 Introduction and Background In a recent paper, W. D. Yu [6] describes the kinds of errors committed by coders working on Lucent Technologies advanced 5ESS switching system. This system's reliability is now dependent on the correct functioning of several million lines of source code.1 Yu not only categorizes the errors, but enumerates within some categories the technical guidelines developed to overcome problems. Yu's paper's advice mirrors, in some respects, the recommendations in Maguire's Writing Solid Code [4], a book brought to my attention several years ago for source material in a software engineering undergraduate course. This ge- nial book explains techniques for avoiding pitfalls in programming in C, and contains valuable advice for intermediate or advanced C language programmers.

  • Chapter 9 on the Early History and Impact of Unix Tools to Build the Tools for a New Millennium
    Chapter 9 On the Early History and Impact of Unix Tools to Build the Tools for a New Millennium “When the barbarian, advancing step by step, had discovered the native metals, and learned to melt them in the crucible and to cast them in moulds; when he had alloyed native copper with tin and produced bronze; and, finally, when by a still greater effort of thought he had invented the furnace, and produced iron from the ore, nine tenths of the battle for civilization was gained. Furnished, with iron tools capable of holding both an edge and a point, mankind were certain of attaining to civilization.” Lewis Henry Morgan “When Unix evolved within Bell Laboratories, it was not a result of some deliberate management initiative. It spread through channels of technical need and technical contact.... This was typical of the way Unix spread around Bell Laboratories.... I brought out that little hunk of history to point out that the spread and success of Unix, first in the Bell organizations and then in the rest of the world, was due to the fact that it was used, modified, and tinkered up in a whole variety of organizations.” Victor Vyssotsky “UNIX is a lever for the intellect.” John R. Mashey Iron Tools and Software Tools Our era is witnessing the birth of an important new technology, different from any in the past. This new technology is the technology of software production. The new tools of our era are tools that make it possible to produce software. Unlike the tools forged in the past, software tools are not something you can grab or hold.
