The Telecom Engineering Center (TEC) is an organization in India that provides testing and certification services for telecom products and equipment. While TEC primarily focuses on telecommunications equipment, including network infrastructure, devices, and systems, they may also provide certification services for feedback devices used in the telecom industry.
However, it's important to note that I don't have access to the latest information or updates beyond my September 2021 knowledge cutoff. Therefore, I recommend reaching out directly to the Telecom Engineering Center (TEC) or visiting their official website to obtain the most up-to-date and accurate information regarding certification requirements for feedback devices in the telecom industry. They will be able to provide you with specific details about the certification process, eligibility criteria, and any applicable standards or regulations.
