TATT has done this through the “Equipment Standardisation and Certification Framework for the Telecommunications and Broadcasting Sectors of Trinidad and Tobago” published September 2008. The regulation mandates that telecommunications equipment must be certified by applying to the TATT with the "Equipment Certification Application Form".
