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/
