 Overall, more than 500 active participants, communications equipment manufacturers, service providers, government agencies, academic institutions, and end-users are engaged in TIA's standards setting process.To ensure that these standards become incorporated globally, TIA is also engaged in the International Telecommunication Union (ITU), the International Organization for Standardization (ISO), and the International Electrotechnical Commission (IEC).TIA merged in 2017 with the Quest Forum, home of the TL9000 quality standard for operators, which substantially increased the number of companies under the TIA umbrella.
