A source in a telecom company claimed that a few products have got validation and hoped that other items, in due course, will get the necessary go ahead.

The National Security Directive on Telecommunication Sector (NSDTS) was framed keeping in mind the national security. Under the provisions of NSDTS, the government will declare a list of trusted sources and trusted products for installation in the country's telecom network.

In June this year, the government launched a website for giving clearance to trusted products that telecom operators can install in their network under the NSDTS.

Telecom operators are required to access the website to indicate the telecom products and the vendor from whom they intend to procure the products.
