The TRAI Act was formed in 1997 to regulate the telecom sector and protect consumer interests as the Department of Telecommunications was both the policy maker and competitor in the sector. TRAI was given functions like license management, interconnectivity regulation, and dispute resolution. However, a 2000 amendment was made to give TRAI more independence as a dispute between TRAI and DoT in 1998 showed DoT could still influence policy making. The amendment made TRAI an independent regulatory body and formed TDSAT to handle disputes. Recent TRAI regulations include tariff orders and promoting digital addressable systems to improve consumer services.
