The main products of ITU-T are Recommendations (ITU-T Recs) – standards defining how
telecommunication networks operate and interwork. See below list for access. ITU-T Recs have
non-mandatory status until they are adopted in national laws. Levels of compliance are however
high due to international applicability and the high quality guaranteed by the ITU-T’s
secretariat and members from the world’s foremost ICT companies and global administrations.
There are well over 3000 Recommendations in force on topics from service definition to network
architecture and security, from broadband DSL to Gbit/s optical transmission systems to next-generation
networks (NGN) and IP-related issues, all together fundamental components of today’s information
and communication technologies (ICTs).
Membership of ITU-T gives exclusive rights to access working documents of standards
under development – tomorrow’s ICTs. The vast majority of all Recommendations are available
in electronic (PDF) form free of charge to all once a final editing process is complete. Texts that
are not free of charge include common ITU-T | ISO / IEC
texts for which special arrangements exist. Find out more about membership here.
