| Title: Numbering Resource Optimization | |
| Abstract: In 1999, the Commission released the Numbering Resource Optimization Notice of Proposed Rulemaking (Notice) in CC Docket 99-200. The Notice examined and sought comment on several administrative and technical measures aimed at improving the efficiency with which telecommunications numbering resources are used and allocated. It incorporated input from the North American Numbering Council (NANC), a Federal advisory committee, which advises the Commission on issues related to number administration. In the Numbering Resource Optimization First Report and Order and Further Notice of Proposed Rulemaking (NRO First Report and Order), released on March 31, 2000, the Commission adopted a mandatory utilization data reporting requirement, a uniform set of categories of numbers for which carriers must report their utilization, and a utilization threshold framework to increase carrier accountability and incentives to use numbers efficiently. In addition, the Commission adopted a single system for allocating numbers in blocks of one thousand, rather than ten thousand, wherever possible, and established a plan for national rollout of thousands-block number pooling. The Commission also adopted numbering resource reclamation requirements to ensure that unused numbers are returned to the North American Numbering Plan (NANP) inventory for assignment to other carriers. Also, to encourage better management of numbering resources, carriers are required, to the extent possible, to first assign numbering resources within thousands blocks (a form of sequential numbering). In the NRO Second Report and Order, the Commission adopted a measure that requires all carriers to use at least 60 percent of their numbering resources before they may get additional numbers in a particular area. That 60 percent utilization threshold increases to 75 percent over the next three years. The Commission also established a five-year term for the national Pooling Administrator and an auditing program to verify carrier compliance with the Commission's rules. Furthermore, the Commission addressed several issues raised in the Notice, concerning area code relief. Specifically, the Commission declined to amend the existing Federal rules for area code relief or specify any new Federal guidelines for the implementation of area code relief. The Commission also declined to state a preference for either all-services overlays or geographic splits as a method of area code relief. Regarding mandatory nationwide ten-digit dialing, the Commission declined to adopt this measure at the present time. Furthermore, the Commission declined to mandate nationwide expansion of the "D digit" (the "N" of an NXX or central office code) to include 0 or 1, or to grant state commissions the authority to implement the expansion of the D digit as a numbering resource optimization measure at the present time. In the NRO Third Report and Order, the Commission addressed national thousands-block number pooling administration issues, including declining to alter the implementation date for covered CMRS carriers to participate in pooling. The Commission also addressed Federal cost recovery for national thousands-block number pooling, and continued to require States to establish cost recovery mechanisms for costs incurred by carriers participating in pooling trials. The Commission reaffirmed the Months-To-Exhaust (MTE) requirement for carriers. The Commission declined to lower the utilization threshold established in the Second Report and Order, and declined to exempt pooling carriers from the utilization threshold. The Commission also established a safety valve mechanism to allow carriers that do not meet the utilization threshold in a given rate center to obtain additional numbering resources. In the NRO Third Report and Order, the Commission lifted the ban on technology-specific overlays (TSOs), and delegated authority to the Common Carrier Bureau, in consultation with the Wireless Telecommunications Bureau, to resolve any such petitions. Furthermore, the Commission found that carriers who violate our numbering requirements, or fail to cooperate with an auditor conducting either a "for cause" or random audit, should be denied numbering resources in certain instances. The Commission also reaffirmed the 180-day reservation period, declined to impose fees to extend the reservation period, and found that State commissions should be allowed password-protected access to the NANPA database for data pertaining to NPAs located within their State. The measures adopted in the NRO orders will allow the Commission to monitor more closely the way numbering resources are used within the NANP, and will promote more efficient allocation and use of NANP resources by tying a carrier's ability to obtain numbering resources more closely to its actual need for numbers to serve its customers. These measures are designed to create national standards to optimize the use of numbering resources by: (1) Minimizing the negative impact on consumers of premature area code exhausts; (2) ensuring sufficient access to numbering resources for all service providers to enter into or to compete in telecommunications markets; (3) avoiding premature exhaust of the NANP; (4) extending the life of the NANP; (5) imposing the least societal cost possible, and ensuring competitive neutrality, while obtaining the highest benefit; (6) ensuring that no class of carrier or consumer is unduly favored or disfavored by the Commission's optimization efforts; and (7) minimizing the incentives for carriers to build and carry excessively large inventories of numbers. In NRO Third Order on Recon in CC Docket No. 99-200, Third Further Notice of Proposed Rulemaking in CC Docket No. 99-200 and Second Further Notice of Proposed Rulemaking in CC Docket No, 95-116, the Commission reconsidered its findings in the NRO Third Report and Order regarding the local Number portability (LNP) and thousands-block number pooling requirements for carriers in the top 100 Metropolitan Statistical areas (MSAs). Specifically, the Commission reversed its clarification that those requirements extend to all carriers in the largest 100 MSAs, regardless of whether they have received a request from another carrier to provide LNP. The Commission also sought comment on whether the Commission should again extend the LNP requirements to all carriers in the largest 100 MSAs, regardless of whether they receive a request to provide LNP. The Commission also sought comment on whether all carriers in the top 100 MSAs should be required to participate in thousands-block number pooling, regardless of whether they are required to be LNP capable. In addition, the Commission sought comment on whether all MSAs included in Combined Metropolitan Statistical Areas (CMSAs) on the Census Bureau's list of the largest 100 MSAs should be included on the Commission's list of the top 100 MSAs. In the NRO Fourth Report and Order and Further Notice of Proposed Rulemaking, the Commission reaffirmed that carriers must deploy LNP in switches within the 100 largest Metropolitan Statistical Areas (MSAs) for which another carrier has made a specific request for the provision of LNP. The Commission delegated the authority to state commissions to require carriers operating within the largest 100 MSAs that have not received a specific request for LNP from another carrier to provide LNP, under certain circumstances and on a case-by-case basis. The Commission concluded that all carriers, except those specifically exempted, are required to participate in thousands-block number pooling in accordance with the national rollout schedule, regardless of whether they are required to provide LNP, including commercial mobile radio service (CMRS) providers that were required to deploy LNP as of November 24, 2003. The Commission specifically exempted from the pooling requirement rural telephone companies and Tier III CMRS providers that have not received a request to provide LNP. The Commission also exempted from the pooling requirement carriers that are the only service provider receiving numbering resources in a given rate center. Additionally, the Commission sought further comment on whether these exemptions should be expanded to include carriers where there are only two service providers receiving numbering resources in the rate center. Finally, the Commission reaffirmed that the 100 largest MSAs identified in the 1990 U.S. Census reports as well as those areas included on any subsequent U.S. Census report of the 100 largest MSAs. In the NRO Order and Fifth Further Notice of Proposed Rulemaking, the Commission granted petitions for delegated authority to implement mandatory thousands-block pooling filed by the Public Service Commission of West Virginia, the Nebraska Public Service Commission, the Oklahoma Corporation Commission, the Michigan Public Service Commission, and the Missouri Public Service Commission. In granting these petitions, the Commission permitted these states to optimize numbering resources and further extend the life of the specific numbering plan areas. In the Further Notice of Proposed Rulemaking, the Commission sought comment on whether it should delegate authority to all states to implement mandatory thousands-block number pooling consistent with the parameters set forth in the NRO Order. | |
