TELECOMMUNICATION ENGINEERING CENTRE (TEC): The telecom industry's evolution, from the telegraph to modern global networks, showcases technological advancements and the importance of telecommunications in connecting people and businesses worldwide. In the early 2000s, liberalization and innovation led to mobile phone proliferation, internet expansion, and wireless communication growth. To ensure high-quality and compliant telecom equipment and services, India established the Telecommunication Engineering Centre (TEC) in 1991. Operating under the Department of Telecommunications (DoT), TEC sets technical standards, fostering a robust telecom infrastructure and enabling better communication for India's population.

    TEC is responsible for publishing specifications that establish quality measures for telecom equipment. These specifications are categorized into three types:

  • Generic Requirements (GRs)
  • Interface Requirements (IRs)
  • Service Requirements (SRs)
    • By establishing these specifications, TEC helps maintain a high level of quality and performance across the telecom industry in India. Compliance with TEC's standards is essential for manufacturers, service providers, and other stakeholders to ensure the smooth functioning and interconnectivity of telecom networks and services in the country.


      The Telecommunication Engineering Centre (TEC) in India offers various approvals for telecom equipment and services:

      Mandatory Testing and Certification of Telecom Equipment (MTCTE): Compulsory for telecom equipment sold or used in India, ensuring compliance with technical parameters and Essential Requirements (ERs).

      Interface Approval: Given to equipment interacting with standard network interfaces, ensuring seamless connectivity with other telecom systems.

      Service Provider Approval: Licenses for telecom service providers to operate in India, ensuring adherence to technical and regulatory requirements.
