CEPT.ORG. ECO. T Recommendations. 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 over 4000 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).
