TEC Approval (Diligence Certifications)

Introduction to TEC Approval

Back in the early 2000s, the telecommunications industry was among the most dynamic and transformative industries in the world economy. Given the onset of digital technologies, the quick pace of liberalization, and rising consumer demand, telecom had grown far beyond mere voice communications. Presently, it has encompassed a whole array of services, including voice and video calls, internet connectivity, data transmission, and cloud communication, enabling a faint connectivity stroke anywhere across the planet.

Telecommuting keeps the other side of a digital infrastructure alive. It connects people with other people, businesses, and governments alike, allowing the functioning of the ever-expanding universe. Generally, the business is divided into three major sub-sectors: equipment and apparatus for telecom, telecom services, and wireless communication. These collectively deliver hardware, connectivity, and mobility into our world.

The origin of the term “telecommunication” can be traced back to at least the 1830s, by way of the invention of the telegraph. Back then, this was the very first mechanical device to transmit information over long distances. It would therefore mark the beginning of an industry that would forever change world communication. Technological innovations relevant to the industry—from landlines to satellites and from 2G to 5G—have dramatically changed the face of telecommunications.

In recognition of the increasingly fast advancement of the telecommunication industry, the Government of India created the Telecommunication Engineering Centre (TEC) in 1991. The TEC Certification, which operates as the technical wing of the Department of Telecommunications (DoT), develops standards and ensures interoperability, safety, and quality issues relating to telecommunication equipment used in India. The TEC Certification aims to promote a world-class telecommunication network by certifying that all telecom products comply with regulatory and technical requirements on a stringent basis.

For manufacturers, importers, or sellers of telecom equipment in India, TEC certification is now an essential prerequisite. Under the MTCTE (Mandatory Testing and Certification of Telecom Equipment) scheme, TEC Certification works to get all telecom equipment certified as complying with Indian standards prior to its entry into the market, thus enabling the country in building upon a secure and dependable communication infrastructure.

What is TEC Approval | TEC Certificate Full Form

TEC is short for Telecommunication Engineering Centre, and it is the technical body under the Department of Telecommunications (DoT), Ministry of Communications, Government of India. It is tasked and empowered to formulate and ensure implementation of regulatory standards pertaining to the quality, safety, and interoperability of telecom equipment and services across the country.

The centre was set up to aid the advancement of telecom infrastructure in India and acts as one of the users in deciding the technical framework for the technologies now in use and those on the horizon. By prescribing standards and certification requirements, TEC Certification has thus ensured that telecom networks are efficiently run and secure and reliable enough to really build India’s digital ecosystem.

To assist the government in policy formulation and in evolving technical standards to ensure the safe and secure use of advanced telecommunications technologies in India such as 4G, 5G, IoT, etc., it works with stakeholders from the industry to finalize the assessment parameters of telecom equipment and systems prior to commissioning. This reduces possibilities of network failure or security threats.

The TEC Certification India has developed a structured framework of technical specifications to guide manufacturers, importers, service providers, and test labs. These are categorized essentially into three main groups:

Generic Requirements (GRs)
These include the necessary functional and technical aspects that telecom equipment must abide by, such as performance standards, environmental durability, and safety features.

Interface Requirements (IRs)
These are requirements about how telecom equipment shall interface or connect to other systems and networks, resulting in compatibility and easy integration with international/national communication infrastructures.

Service Requirements (SRs)
Here, quality and operational standards are applied to telecom services to ascertain uniform and reliable user experiences, including call service or internet service-related aspects.

By virtue of these standards and certification processes, the Telecom Engineering Centre (TEC) lays an essential foundation of trust, safety, and innovation for the fast-growing telecom sector within India. The so-called big picture involves creating a telecom network that is ready for the future, with support for the digital initiative of India and international competitiveness.

types

types of TEC Approval | TEC Certification

The Telecommunication Engineering Centre offers different types of approvals to see to it that telecom products meet the required technical standards before being put into deployment. Each kind of approval serves a certain purpose depending on the nature of the product and its specific application. The four major types of TEC approvals are as follows:

1. Type Approval
The Type Approval refers to the testing of telecom equipment and certifying that it conforms to such standards as defined by TEC under the Test Schedule & Test Procedure (TSTP). It primarily concerns the Standard for Products/Equipment of the product, wrongly sometimes called the Generic Requirement (GR).

Testing may be conducted either at the OEM’s premises or in a certified laboratory environment. TEC also accepted test reports on Electromagnetic Compatibility (EMC), Safety, and Environmental Testing issued from laboratories accredited by ILAC signatories.

2. Interface Approval
Interface Approval is meant to certify telecom equipment for compliance with TEC’s standards that govern interface and connectivity features, again under the TSTP method and concerning what is commonly and incorrectly called the product’s Interface Requirement (IR).

Testing may be done at the OEM site or in a controlled lab environment depending upon the stipulations. Test reports from ILAC-accredited laboratories, covering EMC, safety, and environmental specifications, are accepted. In many cases, Interface Approval is mandatory to be obtained from government departments, telecom service providers, or regulatory bodies in order to enter the market or obtain a license.

3. Certificate of Approval (CoA)
The Certificate of Approval (CoA) is given to telecom products that are not covered in existing Generic Requirements (GRs) or Interface Requirements (IRs) specified by TEC. In such a situation, the certification is based on the technical specifications and standards developed by the manufacturer.

Testing procedures remain the same, be it at an OEM facility or a certified laboratory. Test reports relating to EMC, safety, and environmental standards from ILAC-accredited labs are equally valid for this approval.

4. Technology Approval
Technology Approval is in effect for prototypes or early-stage telecom products from C-DOT or elsewhere, from other recognized R&D institutions. This license ensures that innovations in telecom hardware or software undergo technical checks against applicable standards, making them roll-out ready.

Technical Approval is conducted vis-a-vis the respective standards of the product, erstwhile referred to as the Generic Requirement (GR). Testing is carried out either on the OEM premises or in an accredited laboratory, and TEC accepts test results from laboratories that are signatories to ILAC for parameters such as EMC, safety, and environmental performance.

Each broadcast approval assures reliability, interoperability, and safety of telecommunication equipment in India for use. Whether a commercial product being tested, a new innovation, or a system requiring special interface validation, the TEC approval regime would see to equipping the integrity of the country’s telecommunication body.

Benefits of TEC Approval | TEC Certification

  • Market Access: TEC approval acts as a gateway to access the Indian telecommunication market. Without this, it would not be lawful to sell or market products in India.
  • Trust and Reliability: With TEC Approval, the products will be considered reliable and hence trustworthy by consumers and business associates, and thus market credibility will be achieved.
  • Conformity and Standards: The TEC Approval Procedure helps in confirming that telecommunication equipment guarantees presented standards to ensure network quality and safety as a whole.
