administrative.
(ii) Rural telephone companies, as defined in the Communications Act of
1934, as amended, 47 U.S.C. 153(37), that provide telecommunications service
in areas where local number portability has not been implemented shall
report utilization data at the central office code (NXX) level per rate
center in those areas.
(iii) All other reporting carriers shall report utilization data at the
thousands-block (NXX-X) level per rate center.
(6) Reporting frequency. (i) Reporting carriers shall file forecast and
utilization reports semi-annually on or before February 1 for the preceding
reporting period ending on December 31, and on or before August 1 for the
preceding reporting period ending on June 30. Mandatory reporting shall
commence August 1, 2000.
(ii) State commissions may reduce the reporting frequency for NPAs in their
states to annual. Reporting carriers operating in such NPAs shall file
forecast and utilization reports annually on or before August 1 for the
preceding reporting period ending on June 30, commencing August 1, 2000.
(iii) A state commission seeking to reduce the reporting frequency pursuant
to paragraph (f) (6)(ii) of this section shall notify the Wireline
Competition Bureau and the NANPA in writing prior to reducing the reporting
frequency.
(7) Access to data and confidentiality —States shall have access to data
reported to the NANPA provided that they have appropriate protections in
place to prevent public disclosure of disaggregated, carrier-specific data.
(g) Applications for numbering resources —(1) General requirements. All
applications for numbering resources must include the company name, company
headquarters address, OCN, parent company's OCN(s), and the primary type of
business in which the numbering resources will be used.
(2) Initial numbering resources. Applications for initial numbering
resources shall include evidence that:
(i) The applicant is authorized to provide service in the area for which the
numbering resources are being requested; and
(ii) The applicant is or will be capable of providing service within sixty
(60) days of the numbering resources activation date.
(3) Growth numbering resources. (i) Applications for growth numbering
resources shall include:
(A) A Months-to-Exhaust Worksheet that provides utilization by rate center
for the preceding six months and projected monthly utilization for the next
twelve (12) months; and
(B) The applicant's current numbering resource utilization level for the
rate center in which it is seeking growth numbering resources.
(ii) The numbering resource utilization level shall be calculated by
dividing all assigned numbers by the total numbering resources in the
applicant's inventory and multiplying the result by 100. Numbering resources
activated in the Local Exchange Routing Guide (LERG) within the preceding 90
days of reporting utilization levels may be excluded from the utilization
calculation.
(iii) All service providers shall maintain no more than a six-month
inventory of telephone numbers in each rate center or service area in which
it provides telecommunications service.
(iv) The NANPA shall withhold numbering resources from any U.S. carrier that
fails to comply with the reporting and numbering resource application
requirements established in this part. The NANPA shall not issue numbering
resources to a carrier without an OCN. The NANPA must notify the carrier in
writing of its decision to withhold numbering resources within ten (10) days
of receiving a request for numbering resources. The carrier may challenge
the NANPA's decision to the appropriate state regulatory commission. The
state commission may affirm or overturn the NANPA's decision to withhold
numbering resources from the carrier based on its determination of
compliance with the reporting and numbering resource application
requirements herein.
(4) Non-compliance. The NANPA shall withhold numbering resources from any
U.S. carrier that fails to comply with the reporting and numbering resource
application requirements established in this part. The NANPA shall not issue
numbering resources to a carrier without an Operating Company Number (OCN).
The NANPA must notify the carrier in writing of its decision to withhold
numbering resources within ten (10) days of receiving a request for
numbering resources. The carrier may challenge the NANPA's decision to the
appropriate state regulatory commission. The state commission may affirm, or
may overturn, the NANPA's decision to withhold numbering resources from the
carrier based on its determination that the carrier has complied with the
reporting and numbering resource application requirements herein. The state
commission also may overturn the NANPA's decision to withhold numbering
resources from the carrier based on its determination that the carrier has
demonstrated a verifiable need for numbering resources and has exhausted all
other available remedies.
(5) State access to applications. State regulatory commissions shall have
access to service provider's applications for numbering resources. The state
commissions should request copies of such applications from the service
providers operating within their states, and service providers must comply
with state commission requests for copies of numbering resource
applications. Carriers that fail to comply with a state commission request
for numbering resource application materials shall be denied numbering
resources.
(h) National utilization threshold. All applicants for growth numbering
resources shall achieve a 60% utilization threshold, calculated in
accordance with paragraph (g)(3)(ii) of this section, for the rate center in
which they are requesting growth numbering resources. This 60% utilization
threshold shall increase by 5% on June 30, 2002, and annually thereafter
until the utilization threshold reaches 75%.
(i) Reclamation of numbering resources. (1) Reclamation refers to the
process by which service providers are required to return numbering
resources to the NANPA or the Pooling Administrator.
(2) State commissions may investigate and determine whether service
providers have activated their numbering resources and may request proof
from all service providers that numbering resources have been activated and
assignment of telephone numbers has commenced.
(3) Service providers may be required to reduce contamination levels to
facilitate reclamation and/or pooling.
(4) State commissions shall provide service providers an opportunity to
explain the circumstances causing the delay in activating and commencing
assignment of their numbering resources prior to initiating reclamation.
(5) The NANPA and the Pooling Administrator shall abide by the state
commission's determination to reclaim numbering resources if the state
commission is satisfied that the service provider has not activated and
commenced assignment to end users of their numbering resources within six
months of receipt.
(6) The NANPA and Pooling Administrator shall initiate reclamation within
sixty days of expiration of the service provider's applicable activation
deadline.
(7) If a state commission declines to exercise the authority delegated to it
in this paragraph, the entity or entities designated by the Commission to
serve as the NANPA shall exercise this authority with respect to NXX codes
and the Pooling Administrator shall exercise this authority with respect to
thousands-blocks. The NANPA and the Pooling Administrator shall consult with
the Wireline Competition Bureau prior to exercising the authority delegated
to it in this provision.
(j) Sequential number assignment. (1) All service providers shall assign all
available telephone numbers within an opened thousands-block before
assigning telephone numbers from an uncontaminated thousands-block, unless
the available numbers in the opened thousands-block are not sufficient to
meet a specific customer request. This requirement shall apply to a service
provider's existing numbering resources as well as any new numbering
resources it obtains in the future.
(2) A service provider that opens an uncontaminated thousands-block prior to
assigning all available telephone numbers within an opened thousands-block
should be prepared to demonstrate to the state commission:
(i) A genuine request from a customer detailing the specific need for
telephone numbers; and
(ii) The service provider's inability to meet the specific customer request
for telephone numbers from the available numbers within the service
provider's opened thousands-blocks.
(3) Upon a finding by a state commission that a service provider
inappropriately assigned telephone numbers from an uncontaminated
thousands-block, the NANPA or the Pooling Administrator shall suspend
assignment or allocation of any additional numbering resources to that
service provider in the applicable NPA until the service provider
demonstrates that it does not have sufficient numbering resources to meet a
specific customer request.
(k) Numbering audits. (1) All telecommunications service providers shall be
subject to “for cause” and random audits to verify carrier compliance with
Commission regulations and applicable industry guidelines relating to
numbering administration.
(2) The Enforcement Bureau will oversee the conduct and scope of all
numbering audits conducted under the Commission's jurisdiction, and
determine the audit procedures necessary to perform the audit. Numbering
audits performed by independent auditors pursuant to this section shall be
conducted in accordance with generally accepted auditing standards and the
American Institute of Certified Public Accountants' standards for compliance
attestation engagements, as supplemented by the guidance and direction of
the Chief of the Enforcement Bureau.
(3) Requests for “for cause” audits shall be forwarded to the Chief of the
Enforcement Bureau, with a copy to the Chief of the Common Carrier Bureau.
Requests must state the reason for which a “for cause” audit is being
requested and include documentation of the alleged anomaly, inconsistency,
or violation of the Commission rules or orders or applicable industry
guidelines. The Chief of the Enforcement Bureau will provide carriers up to
30 days to provide a written response to a request for a “for cause” audit.
