“TL 9000 certification sets apart vendors, such as ADTRAN, that have invested in themselves to drive the highest levels of global quality in hardware, software and services. The certifications are achieved through a rigorous audit process, with the goal of efficiently providing the highest quality ICT products and services, as well as enhancing overall customer experience,” said Fraser Pajak, CEO of QuEST Forum. “As one of the first companies in the world to achieve TL 9000 certification 15 years ago, ADTRAN has remained steadfast in their commitment to provide high quality products to their global customers.”
