14、quests must be submitted directly to the PA5; 2.5 These administration guidelines were prepared by the industry to be followed on a voluntary basis. However, the FCC has implemented a number of orders and rules referenced by footnote to the appropriate order associated with thousands-block number po
15、oling administration. Should the rules change, the associated text in the guidelines and references would change accordingly. In these guidelines, INC changed the term “NANPA” to “PA”, as appropriate. The FCC orders and rules incorporated in these guidelines are included in 15.0. 2.6 NANP numbering
16、resources shall be assigned to facilitate the most effective and efficient use of a finite numbering resource in order to prevent premature exhaust of an NPA and delay the need to develop and implement costly new numbering plans. Efficient resource management and code conservation are necessary to s
17、tay the industry impacts of expanding the numbering resource (e.g., expansion from 10 to 11 or 12 digits). Impacts of NANP expansion include: a) customer impacts (e.g., dialing, telephone number (TN) changes to advertising and stationery, security systems, etc.); b) Customer Premise Equipment (CPE)
18、modifications; c) domestic and international switching hardware and software modifications; d) operational support systems (OSS) modifications and/or upgrades; and e) reprogramming of non-telecommunications databases that contain TNs. The NANP Resources assigned in this guideline are expected to be
19、used in conformance with this guideline and the related ITU-T recommendations. Misuse of a resource either as defined in this guideline or as defined in ITU-T E.156 “Guidelines for ITU-T action on reported misuse of E.164 number resources” should be reported to the NANPA.6See Section 13 for contact
20、information. 2.7 When a service providers jurisdictional certification, license, or authorization to operate has been revoked, the appropriate regulatory authority should provide written direction and supporting documentation to NANPA and the PA to deny applications for the company name associated w
21、ith the revoked jurisdictional certification, license, or authorization7. 2.8 Block Applicants requesting resources from the industry inventory pool: 5 The PA will provide a report to NANPA of the SPs participating in pooling in a voluntary rate center outside of the top 100 MSAs. If NANPA determine
22、s from the report that an SP is participating in pooling in a voluntary rate center, NANPA will deny a CO Code application for that rate center. 67FCC 00-104 97 and FCC 15-70 53. Thousands-Block Number Pooling Administration Guidelines Final Document ATIS-0300066 March 4, 2016 Page 5 a) service prov
23、iders must provide, as part of their applications for initial numbering resources, evidence (e.g., state commission order or state certificate to operate as a carrier) demonstrating that they are licensed and/or certified to provide service in the area in which they seek numbering resources;8b) are
24、required to provide appropriate evidence (See Section 4.3.1) to the PA that demonstrates they have or will have facilities in place to provide service within 60 calendar days of the numbering resources activation date for initial numbering resources.9Self-certification is not acceptable. c) shall co
25、mply with state commission requests for copies of numbering resource applications (including supporting documentation accompanying applications) within one business day of receiving the request. State commissions have access to service providers applications for numbering resources, including the su
26、pporting documentation that SPs submit via e-mail to the PA to accompany those applications for numbering resources. State commissions may review copies of such applications in PAS, or may request copies of such applications (including supporting documentation accompanying applications) from the ser
27、vice providers operating within their states. Carriers that fail to comply with a state commission request for copies of numbering resource application materials shall be denied numbering resources10 when the state commission demonstrates (e.g. by email or facsimile) to the PA that the carrier faile
28、d to comply with the request.11d) Shall submit a customer letter as supporting documentation to accompany a dedicated code request when requesting a dedicated code for a single customer and MTE and utilization are met or it is the SPs initial request in the rate center. The letter shall be on the cu
29、stomers letterhead documenting the need for 10,000 consecutive telephone numbers, indicating the state and rate center where the numbers are needed, and signed by a party within the customers organization with the authority to make such a request (e.g., officer of the company). The SP shall e-mail t
30、his supporting documentation to the PA, along with the PAS tracking number, immediately after submitting the dedicated code request. When an SP requests dedicated code for a single customer and MTE and utilization are not met, a safety valve waiver is required. 847 CFR 52.15 (g) (2). 947 CFR 52.15 (

Thousands-Block Number Pooling Administration Guidelines Final Document ATIS-0300066 March 4, 2016 Page 6 e) shall donate12numbering resources to the industry inventory pool via the block disconnect process, in accordance with these guidelines and a
32、ny regulatory directives; f) shall establish internal policies and practices that provide for the efficient use and assignment of TNs to end users. These policies and practices shall balance product specifications, market strategies and customer needs with conservation principles to ensure “best pra
33、ctices” in TN utilization; g) shall use available numbers from a contaminated block before assigning TNs from an uncontaminated thousands-block, unless the available numbers in the opened thousands-block are not sufficient to meet a specific customer request13. This requirement shall apply to a serv
34、ice providers existing numbering resources as well as any new numbering resources it obtains in the future.14The exceptions to the sequential numbering requirement are intended to address a customers specific need for TNs that cannot be filled from the service providers opened thousands-blocks, rath
35、er than requests for specific individual numbers (such as vanity numbers); h) shall minimize the use of TNs within thousands-blocks for purposes other than subscriber assignments (e.g., Administrative Numbers); and i) will have a choice to initiate pooled block activation through Service Order Activ
36、ation (SOA) interface to NPAC Service Management System (SMS), or through NPAC personnel. 2.9 The schedule of holidays recognized by the PA will affect the administration of these guidelines. Holidays will not be considered a “calendar day” as a part of any timing of thousands-block allocations in a
37、ssociation with these guidelines. 2.10 SPs and numbering resource administrators are responsible for managing numbering resources in accordance with these guidelines and the orders of applicable regulatory authorities. Both SPs and numbering resource administrators are subject to audits. Further inf
38、ormation may be found in FCC 00-10462, FCC 00-42981-99, FCC 01-362 95-111 and 47CFR52.15(k). 2.11 Audits of the PA and Block Applicants/Holders will be performed by the Audits Branch of the Accounting Safeguards Division in the FCC Wireline Competition Bureau, or other designated agents to: 12An SP
39、can avoid the donation of blocks containing administrative numbers, e.g., TLDNs, Mobile Station Roaming Numbers (MSRN), by consolidating these numbers within blocks it intends to retain in compliance with FCC rules. The porting of TLDNs/MSRNs can cause call delivery to roaming subscribers to fail. 1

Thousands-Block Number Pooling Administration Guidelines Final Document ATIS-0300066 March 4, 2016 Page 7 a) ensure uniformity in application of these guidelines by the PA to all thousands-block requests received by the PA; b) ensure compliance with the
41、se guidelines by Block Applicants and the PA; and c) ensure the efficient and effective use of numbering resources by Block Applicants/Holders and efficient and effective management of numbering resources by the PA. 2.12 These guidelines were developed assuming pre-porting with Efficient Data Repres
42、entation (EDR) as the preferred method of implementation.152.13 It is assumed from a wireline perspective that CO Codes/blocks allocated to a wireline Service Provider are to be utilized to provide service to a customers premise located in the same rate center that the CO Codes/blocks are assigned.
43、Exceptions exist, for example, tariffed services such as foreign exchange service. 2.14 For the purposes of these guidelines, it is assumed that blocks donated to a pool from wireless grandfathered NXXs16cannot be assigned to SPs until regulatory authorities direct how to handle these unique numberi
44、ng resources. Additionally, because these blocks of grandfathered numbers have been donated to the pool, they are excluded from months to exhaust and utilization calculations on the Thousands-Block Months to Exhaust and Utilization Certification Worksheet TN level (Appendix 3) when a service provide
45、r requests additional thousands-blocks for growth. 2.15 The NPAC broadcast rates for activations, disconnects and modifications are set to the following limits to accommodate service provider system thresholds. The maximum number of block requests (activations, disconnects, and/or modifications) the
46、 NPAC can process per NPAC region is: 1,440 block requests per day except for Sundays, a maximum of 720 block requests on Sundays. If the NPAC is unable to meet the effective date established on the Part 1B NPAC Block Holder Data form for block activations and modifications, or on the Part 5 NPAC Th
47、ousands-Block Reclamation form for block disconnects, the NPAC shall notify the SP and PA of the new effective date via email. 2.16 Rate Center Consolidations/Changes 15Refer to NANC Meeting Record, August 1998. 16“Grandfathered” wireless NXXs exist in states where the regulatory agency has allowed
48、wireless carriers to maintain their existing (old) NPA-NXXs in geographic areas (and rate centers) that were assigned a new NPA. Equivalent circumstances occur in some states where the term “grandfathered” is not used, e.g., CO codes not in a correct geographic NPA.
