TEC (Telecommunication Engineering Centre)


Telecommunication Engineering Centre (TEC)


TEC Registration / Certification is given to a Telecom Product or network which will be interfaced with Indian Telecom network. Any Original Equipment Manufacturer and Importer, who wants to sell, import, or use any telecom equipment in India, has to obtain TEC Certificate from Telecommunication Engineering Centre (TEC India), Department of Telecommunications, Ministry of Communications, Government of India.

The Indian Telegraph (Amendment) Rules, 2017, provides that every telecom equipment must undergo prior mandatory testing and certification. The detailed procedure for Mandatory Testing and Certification of Telecom Equipments (MTCTE) under these rules has been notified. The testing is to be carried out by Indian Accredited Labs {which have been designated as CAB (Conformance Assessment Body) by TEC}  and based upon their test reports, the certificate shall be issued by TEC.

Groups and Schemes in TEC

Groups in TEC

Groups in TEC refers to the Grouping of types of equipment for which TEC Certification is mandatory. Types of equipment are grouped according to the time and complexity involved in testing the equipment or evaluating test reports. These types of equipment are divided into three groups:

  • Group A,
  • Group B and
  • Group C.
Schemes in TEC

Below are the 2 types of Certification Schemes for notified Telecom Equipment:

  • General Certification Scheme (GCS)

Under this scheme, the applicant has to submit test wise compliance along with test reports, in respect of parameters included in  Essential Requirements (ERs), from any designated Conformance Assessment Body (CAB).

General Certification Scheme (GCS) is applicable to Group A, Group B and Group C equipment.

  • Simplified Certification Scheme (SCS)

Under this scheme, the applicant has to submit a test wise compliance sheet, along with a Self-Declaration of Conformity (SDoC), in respect of parameters included in ERs. Test reports from CAB are not required to be submitted by the applicant or evaluated by TEC.

Simplified Certification Scheme (SCS) is applicable to Group A equipment.
