ISDN - The Integrated Services Digital Network
Author: Peter Bocker
language: en
Publisher: Springer Science & Business Media
Release Date: 2013-06-29
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.

ISDN Explained Worldwide Network and Applications Technology Third Edition John M. Griffiths and the staff at BT Laboratories, UK ISDN (Integrated Services Digital Network) is now an established communications development and continues to replace modems as a fast transmission mechanism. This significantly updated and expanded third edition of ISDN Explained provides an overview of the principles and applications of ISDN operation and application. Building on the success of the first and second editions, this new version provides more detail on the broadband aspects and adds a complete reference section on the signalling access protocols that control an ISDN connection. Other features in this comprehensive guide include: - complete coverage of the increasing number of supplementary services and the embedded data channel - useful end of chapter questions with solutions included at the end of the text - listing of ISDN terms in French, German and Spanish. As a highly readable introductory guide to ISDN it suits all levels of understanding, and as an authoritative text it is ideal for students in engineering and computing. Practising communications engineers, electrical and electronic engineers and computer communications personnel will also find this essential reading. Visit Our Web Page! http://www.wiley.com/
