Interconnection ensures the access of an operator to the communications infrastructure of another operator, thus enabling the end-users to communicate with the subscribers of other networks.The cost-oriented interconnection tariffs offer each operator equal chances to compete with the operators with significant market power, as well as access to the electronic communications fixed and mobile public infrastructure.

In order to promote competition, ensure the interoperability of electronic communications services and protect the users’ rights and interests, ANCOM adopted a series of measures to prevent abuse from the providers with significant market power.
ANCOM designated the providers with significant market power, imposing on them a series of obligations regarding access to certain facilities in terms of interconnection, cost-orientation of tariffs, separate accounts, as well as obligations regarding transparency and non-discrimination as to the other players on the market. These obligations have been provided in the ANCOM issued decisions regarding:
  •   the regime of interconnection with thefixed public telephone networks
  •   the regime of interconnection with the mobile public telephone networks
By imposing these obligations on the providers with significant market power, ANCOM succeeded removing the main market entry barriers encountered by the new operators.
