Two separate complaints against incumbent telco Bulgarian Telecommunications Company (BTC) have been filed by alternative operators this week, according to the Competition Protection Commission (CPC). The complainants have alleged that BTC is abusing its dominant position and inhibiting competition in the broadband market by obstructing access to the local loop and its ADSL infrastructure. The CPC says it will investigate BTC’s practices – which currently include a policy of only allowing ISPs dial-up access to the local loop, rather than bit-stream access, under its own interpretation of the country’s telecoms law. BTC has also been criticised for charging high rental fees for last-mile access. Alternative operators have been allowed access to the local loop since 1 January 2005.
