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 (International Telecommunication Union) is the United Nations specialized agency
for information and communication technologies – ICTs. It allocates global radio spectrum and satellite orbits, develops the technical standards that ensure networks and technologies seamlessly interconnect, and strives to improve access to ICTs to underserved communities worldwide.

ETSI, the European Telecommunications Standards Institute, produces globally-applicable standards for Information and Communications Technologies (ICT), including fixed, mobile, radio, converged, broadcast and internet technologies.
