Internet Providers Criticize Leased Line Tariffs Bisnis Indonesia, Sept. 26, 2006, T2 JAKARTA: The Association of Indonesian Internet Service Providers urge network operators to lower leased line tariffs to allow a healthy competition in providing Internet services for retail customers. Chairman of the Association Sylvia W. Sumarlin said that network operators, which also provide direct internet services to customers, have disturbed ISP businesses. “Every day, a lot of ISP customers switch to network operators because they provide cheaper tariffs to access Internet,” she said to Bisnis yesterday.
