The document is a Provisional Test Guide issued by the Telecommunication Engineering Centre (TEC) of India, which establishes the test schedule and procedures for evaluating the conformity, functionality, requirements, and performance of the International Private Leased Circuits Traffic Interception and Legal Monitoring (IPLC-TLMS) system intended for implementation in the Indian telecommunications network.

The guide replaces and updates the 2007 version, incorporating changes defined in the generic specification GR 49020:2025.

It is structured for use by official test teams and covers everything from general information about the applicant and equipment configuration to the exhaustive details of each test that must be performed to verify compliance.

WHOM DOES IT IMPACT?

The direct impact is on international telecommunications service providers, interception equipment manufacturers and suppliers, government law enforcement agencies, and technical and regulatory compliance areas.

CONCLUSION:

The guide establishes a critical technical and regulatory framework to ensure that lawful interception and monitoring of IPLC traffic is carried out with high accuracy, security, and availability, protecting the privacy of non-target users and ensuring effective cooperation between operators and authorities.
