This text goes into the principles of all facets of the ISDN operation, giving an overview to set the operations in context and to act as an introduction to detailed standards, recommendations and specifications. The author looks at short and long term applications of ISDN that have become apparent since the first edition in 1990. New terminal equipment has emerged and this is described in chapter 8. Other additions include a more detailed consideration of supplementary services and an update on the situation on inter-PABX signalling and Broadband ISDN. An annex explaining the use of SDL in specifying ISDN interfaces is provided.
Trusted telecommunications expert Uyless Black has put together a complete yet accessible guide to the basics of narrowband signaling and the specifications for ISDN and SS7. He also discusses the potential applications of the protocol, including video conferencing, Internet access, and mobile and wireless 800 service.
This introduction to ISDN has been revised and expanded for this edition. It places special emphasis on ATM and Frame Relay applications, products and services. New material is included on NI (National ISDN) and AIN (Advanced Intelligent Network). There is
The present state of development of communication technology is characterized by two features, namely the digital representation of all signals transrnitted and processed, irrespective of information type - voice, text, data or images - and the integration of systems and services, this integration only being completely possible using digital technology. The boundaries between switching and transmission are shifting, and functions are being redefined and redistributed between terminals and communication networks. Multiservice terminals - unlike telephones, teleprinters, video data terminals - are designed to handle more than one information type. Lastly, the communication network allows voice, text, data and video information to be transmitted on the same circuit; the user obtains access to this network via a non dedicated "communication socket". The essential features of this Integrated Services Digital Network (ISDN) have been standardized over the last eight years by experts from all over the world under the aegis of the CCITT 1), the international standardizing body of the carriers of public communication networks. All the leading network carriers are working towards ISDN implementation because of the substantial benefits it will offer to users, network carriers and manufacturers alike: Users will obtain additional and advanced services, most of them designated to cater for the growth in non-voice traffic. The ISDN subscriber access will also enable users to operate existing systems more cost-effectively than via various dedicated networks.
Completely updated, revised, and expanded, this second edition includes the most up-to-date treatment of broadband ISDN. The new edition also features many examples, more than 100 clear illustrations, an updated list of acronyms and abbreviations, and a complete glossary for easy reference.
This is an elementary textbook on an advanced topic: broadband telecommunica tion networks. I must declare at the outset that this book is not primarily intended for an audience of telecommunication specialists who are weIl versed in the concepts, system architectures, and underlying technologies of high-speed, multi media, bandwidth-on-demand, packet-switching networks, although the techni caIly sophisticated telecommunication practitioner may wish to use it as a refer ence. Nor is this book intended to be an advanced textbook on the subject of broadband networks. Rather, this book is primarily intended for those eager to leam more about this exciting fron tier in the field of telecommunications, an audience that includes systems designers, hardware and software engineers, en gineering students, R&D managers, and market planners who seek an understand ing of local-, metropolitan-, and wide-area broadband networks for integrating voice, data, image, and video. Its primary audience also includes researchers and engineers from other disciplines or other branches of telecommunications who anticipate a future involvement in, or who would simply like to leam more about, the field of broadband networks, along with scientific researchers and corporate telecommunication and data communication managers whose increasingly sophis ticated applications would benefit from (and drive the need for) broadband net works. Advanced topics are certainly not ignored (in fact, a plausible argument could be mounted that aIl of the material is advanced, given the infancy of the topic).
ISDN (Integrated Services Digital Networking) is a major communications development whereby voice, data and video, for instance, are integrated and transmitted over an extensive network of digital exchanges. It is an extremely fast mechanism for transmitting data.; Now in its 3rd edition, this title provides an overview of the principles and applications of ISDN (Integrated Services Digital Networking) operations and applications. More information on broadband aspects is included and there is an explanation of Signalling Access Protocols.
