The building blocks would be divided by the BOCs as follows: Basic Service Elements, Basic Serving Arrangements, Complimentary Network Services, and Ancillary Network Services. Even if a BOC did not want to enter the ESP market they were required to file with the FCC their ONA plans. If the BOCs successfully filed an ONA plan with the Commission, it would then be permitted to provide integrated ESP services without filing a CEI plan. The Computer Inquiries III provided safeguards that fell upon different entities into the following categories: annual ONA reporting, network information disclosure, cross-subsidization prohibitions, accounting safeguards, and customer proprietary network information. In 1989, the FCC created a reporting structure that the BOCs are required to file quarterly, semi-annual, and annual reports for their ONA that include the following information: "annual projected deployment schedules for ONA service, by type of service (BSA, BSE, CNS), in terms of percentage of access lines served system-wide and by market area; disposition of new ONA service requests from ISPs; disposition of ONA service requests that have previously been designated for further evaluation; disposition of ONA service requests that were previously deemed technically infeasible; information on Signaling System 7 (SS7), Integrated Services Digital Network (ISDN), and Intelligent Network (IN) projected development in terms of percentage of access lines served system-wide and on a market area basis; new ONA services available through SS7, ISDN, and IN; progress in the IILC (now NIIF) on continuing activities implementing service-specific and long-term uniformity issues; progress in providing billing information including Billing Name and Address (BNA), line-side Calling Number Identification (CNI), or possible CNI alternatives, and call detail services to ISPs; progress in developing and implementing Operation Support Systems (OSS) services and ESP access to those services; progress on the uniform provision of OSS services; and a list of BSEs used in the provision of BOC/GTE's own enhanced services." "In addition, the BOCs are required to report annually on the unbundling of new technologies arising from their own initiative, in response to requests by ISPs, or resulting from requirements imposed by the Commission." As of February 2011, the FCC to better serve the public interest have temporarily waived the reporting of these ONA reports to eliminate added expenses to the BOCs in preparing these reports. Carriers are required by the FCC to disclosure to the public all information relating to network design and technical standards and information affecting changes to the telecommunications network which would affect either inter-carrier interconnection or the manner in which customer-premises equipment is attached to the interstate network prior to implementation and with reasonable advance notification.
