A comprehensive overview of today's networked world, offering just the right amount of technical detail
Now updated to cover the latest wireless and broadband technologies, this lucid overview describes today's communications systems and networks-voice, data, video, and multimedia-and explains how they are likely to evolve and converge. Communications Systems and Networks delivers plain-English explanations of all the technical fundamentals-and puts everything in context by addressing standards, regulations, and the real-world outlook for legacy, contemporary, and emerging technologies. Whether you're a networking pro who wants to gain some perspective or you just want to understand our increasingly interconnected world, this is the one book you need to see the big picture.
Inside, you'll find clear explanations of:
* Essential concepts such as circuits, switches, and digital and analog transmission
* Transmission media--from twistedpair to satellite, microwave, infrared, and fiber optics
* Data communications, from LANs and WANs to broadband and 3G wireless
* Recent and emerging voice technologies, including Voice over Frame Relay (VoFR), Voice over ATM (VoATM), Voice over IP (VoIP), and Voice over DSL (VoDSL)
* Broadband access technologies, including Digital Subscriber Line (DSL), cable modems, Free Space Optics (FSO), and Wireless Local Loop (WLL)
* Internet and Web standards, topology, technologies, and protocols, including WAP and i-Mode
* Video and multimedia networking, from HDTV to videoconferencing systems
* Network convergence issues, such as standards, regulation, addressing, and Quality of Service (QoS)
* The latest regulatory flash points, from line sharing to Internet wiretapping
Synopsis
Communication Systems and Networks erscheint jetzt neu in der 3. aktualisierten Auflage.
Von der Vorg ngerauflage wurden ber 40.000 Exemplare verkauft.
Konvergenz ist verwirrend, aber wichtig und nicht zuletzt eine unausweichliche Tatsache.
In diesem Band erkl rt Branchenexperte Ray Horak, wie sich die Verschmelzung von Sprach- und Datennetzen entwickelt hat, und wie sie sich in Zukunft in einer informationsbasierten Wirtschaft entwickeln wird.
Zun chst gibt der Autor eine Einf hrung in die Grundlagen der Kommunikationstechnologie und geht dann auf die Grundlagen der bertragungsmedien ein (von verdrillten - ber Koaxialkabel, Satelliten- und Glasfaser bertragung).
Dann erfolgt ein berblick ber die Grundlagen von Sprachsystemen, angefangen bei Legacy Netzwerken, wie Telefonsysteme, ber PBXs, Centrex, Automatic Call Distributors und Computer Telephony Integration.
Auch die Grundlagen der Datenkommunikation werden ausf hrlich betrachtet; darunter grundlegende LAN- und WAN-Technik, Modems und andere Ger te zur Daten bermittlung, Breitband-Infrastruktur und Netzwerkdienste sowie Protokolle und Ausstattung, mit deren Hilfe das Internet zu einer globalen Realit t wird.
Dar ber hinaus werden auch aufstrebende Technologien und Anwendungen diskutiert, die sich nach und nach etablieren, wie z.B. drahtlose Netze und digitale Videonetze.
Communication Systems and Networks - die ultimative Pflichtlekt re f r alle, die sich einen fundierten berblick ber aktuelle Kommunikationstechnologien verschaffen wollen.

Now updated to cover the latest technologies, including wireless networking and digital video, this indispensable guide by telecom pundit Ray Horak gives IT professionals and operations managers the "big picture" on convergence -- the ongoing integration of voice, data, and video communications systems -- along with incisive prognostications and just the right amount of technical detail for sound decision-making.
Synopsis
* Convergence is confusing. Convergence is critical. And convergence is real. In this book, industry pundit Ray Horak describes how the merging of voice and data networks has evolved and is likely to evolve as we move toward an information-based economy.
* Beginning with the fundamentals of communications technology, the book grounds the reader in basic telecommunications concepts including circuits (dedicated, switched and virtual), switches (circuit, packet, and frame), and the issues involved in digital and analog transmission.
* Describes the rudiments of transmission media, from twisted pair and coaxial cable to satellite and fiber-optic transmission.
* Introduces the basics of voice systems, beginning with legacy networks like key telephone systems and including PBXs, Centrex, Automatic Call Distributors, and Computer Telephony Integration (CTI).
* Explains the fundamentals of data communications, including basic LAN and WAN engineering, modems and other forms of data communications equipment, broadband infrastructure and network services, and the protocols and equipment that make the global Internet a reality.
* Considers some of the emerging technologies and applications just now gaining widespread acceptance, including wireless networks and digital video networks, along with the economic and regulatory forces likely to determine the shape of the networked world of the 21st Century, as well as the speed with which we can expect to see it implemented.
* Previous edition sold 40,000+ copies.
