Adoption of TSDSI/ International Telecom Standards

A standard is a document that applies collectively to codes, specifications, recommended practices, classifications, test methods, and guides, which have been prepared by a standards developing organization or group, and published in accordance with established procedures. Adoption of International standards after public consultation promotes coherence with International Standards and helps in expanding portfolio of national standards. It is important that the Standards developed or International Standards transposed by TSDSI (or any other Standards Development Organization) are adopted by TEC for use in India nationally rather than simply relying on the use of these Standards themselves.

A committee was constituted to define the process of adoption/ratification of standards. The committee recommended that TEC shall implement the standard adoption process with the help of an institutional framework consisting  of Telecom Standards advisory committee (TSCA), consultative Committee(s)(CC) and task force(s) setup for the purpose. The process shall be coordinated by Standardization division. The standard adopted by TEC shall be regarded as the national standard of India. The committee formulated a Standardization Guide for adoption of TSDSI/ International Telecom Standards.


The Standards ratification /adoption process  in brief is as follows –

On receipt of a proposal for ratification/ adoption in TEC, the same shall be examined to see whether the standard proposed for adoption is duly approved by General body/ governing body of TSDSI / TSDO concerned and whether the national requirements have been represented / taken care of during standardization /transposition.

The proposal will then be put up to as Apex level committee (say TSAC) for examination whether the standard can be adopted as national standard . Proposed standard once agreed for adoption as national standard shall become draft TEC standard for circulation. The draft standard shall then be circulated electronically for inviting public comments .

If the proposal is not agreed/approved for adoption as national standards, TSDSI or the source of the proposal may be intimated accordingly. A draft standard shall normally be available for public comment irrespective of its national or international origin. Further only technical content or the Amendments affecting the technical content of standard shall be open for public comments.

Resolution of comments: The comments received on wide circulation of the draft shall be compiled and scrutinized/ reviewed. If no comments other than the editorials are received, the draft shall be recommended for ‘identical adoption’ after making editorial changes. If comments/ deviations related to incorporation of/ amendment in respect of national requirements/ parameters/ levels are received, the standard shall be modified accordingly in a manner consistent with ‘ISO/ IEC guide 21’ and submitted for approval as ‘modified adoption’. Process of seeking comments and discussion shall be repeated to resolve all the issues. After completion of the process, the draft shall be finalized by consultative committee and submitted for approval.

Further, Whether the proposal is approved for adoption or not will be notified and in case of any discrepancy in comments, there will be a procedure for the same.


The detailed process of  adoption of International standard is available at point 6  of the Adoption Guide.
