ITU-T Recommendations and selected Handbooks - DVD-ROM
2016   Publication Notice with Order Form

The enhanced DVD provides vastly improved search tools, including a detailed search-by-content that covers all ITU-T Recommendations in force. Recommendations not yet available in their final edited format are included in their provisional pre-published form. A wide range of electronic attachments are also included and or referenced for direct-download from the ITU website. The DVD also includes a searchable collection of selected 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. This quarterly DVD was available either individually or through a yearly subscription that covers four editions at a discounted rate, now replaced by USB Key.

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.

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.
