TRAI has issued the Telecom Regulatory Authority of India Repealing Regulations, 2023, to repeal the older quality of service (QoS) rules of December 2001 that it feels are no longer relevant. The older regulation of 2001 was applicable to all basic service operators and ISPs, including state-run BSNL, MTNL and erstwhile VSNL (rechristened Tata Communications).
