ITU Publications : Standardization (ITU-T)

The ITU is the leading publisher of telecommunication technology, regulatory and standard information. Over 4'500 titles in printed form and growing  number on CD-ROM, DVD and Online.


Telecommunication Standardization Sector (ITU-T)

The main products of ITU-T are the Recommendations. At present, more than 3,000 Recommendations (Standards) are in force. Recommendations are standards that define how telecommunication networks operate and interwork. ITU-T Recommendations are non-binding, however they are generally complied with due to their high quality and because they guarantee the interconnectivity of networks and enable telecommunication services to be provided on a worldwide scale. Available individually, as a collection on DVD or with a 12 month-access Online subscription

ITU-T Recommendations and selected Handbooks - DVD-ROM
2014  New!   Publication Notice with Order Form

Each quarterly edition of this DVD-ROM contains the most current set of ITU-T Recommendations in force. Some Recommendations, not yet available in their final edited format, are included in their provisional prepublished form. Associated software programs are in general included in the DVD-ROM, unless their volume prevents it, in which case they should be bought separately. Also included is a collection of technical Handbooks developed by the ITU Telecommunication Sector in fields such as mitigation measures for telecommunication installations and their protection against electromagnetic effects, formal languages, outside plant, network security, quality of service and network planning.
Available inCD/DVD   paper   electronic file

Mitigation measures for telecommunication installations
2008   Publication Notice with Order Form

This handbook describes case studies, supplied by ITU-T Study Group 5 members, of electromagnetic compatibility (EMC) interference problems that have affected telecommunication systems related to emission and immunity, overvoltage and overcurrent, and the solutions to such problems. This handbook also indicates typical sources of interference as well as the solutions that can be used to restore correct service to the system or to avoid any such problems before they manifest themselves. Whilst this handbook does not cover measurement methods or how to measure emissions, overvoltage or overcurrent, as these are covered within other ITU-T Recommendations, it does, through the case studies, suggest how to detect certain problems. The electronic version of part 2 is free of charge. www.itu.int/ITU-T/mitigation/mitigation-p2.html

Earthing and Bonding
2003   Publication Notice with Order Form

This ITU-T handbook on Earthing and Bonding is for use by engineers designing telecommunication systems, especially those concerned with applying protective measures. It aims to give the user a background to various terms used within the telecommunication and power industry regarding earthing and bonding of equipment and structures (Chapter 1) in various parts of the world. The concepts of earthing and bonding are described (Chapter 2) together with how to implement such methods (Chapters 3 and 4), detailing why these are necessary and what the results may be if they are not performed correctly. The final section of the handbook shows how to evaluate and maintain the effectiveness/quality of the earthing systems and bonding networks thus created.

Quality of service and network performance
The QoS Handbook sets out to specify network service quality parameters that enable services to be offered to customers/users in order to satisfy customers'/users' quality of service expectations. These parameters relate to both implementation and ongoing use of the service. Service quality is also related to all aspects of network assessment and management of the network.
