12、) directed the Industry Numbering Committee (“INC”) to examine the issue of “the technical feasibility of modifying the existing toll free database to make only those 500 and 900 numbers that are assigned to local exchange carrier portable and file a report with the FCC within twelve months of the e

13、ffective date of the order.” The Commission further asked that this examination consider whether the technical feasibility could be achieved through modifying the existing toll free database or through another system. The INC accepted this directive and accordingly, submits the following report. In

14、addition, INC sought the expertise of the Network Interconnection/Interoperability Forums (“NIIF”) Networks Interconnection/Architecture Committee (“NIAC”) on those aspects of this report pertaining to interconnection and architecture. Thus, the consensus reflected in this report is that of the INCs

15、 and where pertaining to architectures, the NIIFs NIAC (hereinafter the “NIIF”) as well. The NIIF is also sponsored by the Alliance for Telecommunications Industry Solutions (“ATIS”). The INC has interpreted the FCCs directive associated with portability for local exchange carrier (“LEC”) 500 and 90

16、0 numbers to mean that only 500 and 900 numbers assigned to LECs need be portable, and that such numbers would be portable only between LECs in the United States.1Accordingly, 500 or 900 numbers assigned to non-LECs (e.g. interexchange carriers or CMRS (“Commercial Mobile Radio Service”) providers)

17、would not be portable and subscribers assigned these numbers, who choose to change service providers, would require a number change. Similarly, a subscriber assigned a LEC 500 or 900 number who choose to migrate their service to a non-LEC service provider would also require a number change. In this

18、report, the network architecture(s) that could be used to support portability of LEC 500/900 numbers are described. In addition, the report examines the impact of portability for LEC 500 and 900 numbers on number administration, resource utilization, network elements, and end users. Within number ad

19、ministration, the areas of assignment guidelines, the pooling of numbers and relief planning are also considered. The INC and NIIF submits that the network architecture and call processing flows described in the previously developed INC Report on PCS N00 Portability could be used to support LEC 500/

20、900 portability2. It is estimated that the development and 1Any reference to LEC(s) in this document refers only to FCC-regulated LECs. 2INC Report on PCS N00 Portability, INC 95-0512-010, see Attachment 1. deployment of this architecture could take up to forty-eight months following FCC direction.

21、The use of the infrastructure currently in place to support portability of 800 numbers modified and/or expanded as necessary - for use as the vehicle for the implementation of 500 and/or 900 portability is also examined. The 800 Service Management Team the industry organization responsible for the d

22、esign and maintenance of the 800 Service Management System (“SMS”)indicates that the necessary effort for a 500/900 SMS based on the 800 SMS would take from 1.5 to 2 years from the date of firm, fully defined requirements for the SMS and appropriate client authorization and tariff approvals. The SMS

23、 portion of the development represents only a part of the necessary effort; further development of network switches and routing data bases would be required to interface with a 500/900 SMS required within the four year period. It is concluded that the capabilities necessary for the support of LEC 50

24、0 and 900 portability are not currently available, but that the technology to provide such portability is understood and could be developed with the associated effort and expense. However, and most importantly, the INC and the NIIF concluded that portability of only LEC 500 and 900 numbers would be

25、confusing to end users, could favor one industry segment over another, would not promote the most efficient utilization of the resources, and would be complex, time consuming and expensive to implement. Consequently, it is the unanimous opinion of the INC and the NIIF that number portability for LEC

26、-only 500 and 900 assigned numbers should not be implemented because it is not prudent; nor is it technically feasible using existing network and administrative data base capabilities.

27、Rulemaking, In the Matter of Telephone Number Portability, CC Docket No. 95-116/RM 8535 (FCC 96-286) Adopted: June 27, 1996, Released: July 2, 1996 1.0 INTRODUCTION - In paragraph 198 of its First Report And Order And Further Notice Of Proposed Rulemaking, (hereinafter the “First Report and Order”)

28、(In the Matter of Telephone Number Portability, CC Docket No. 95-116/RM 8538 (FCC 96-286) Adopted: June 27, 1996; Released: July 2, 1996), the Federal Communications Commission (“FCC” or “Commission”) directed the Industry Numbering Committee (“INC”) to examine the issue of “the technical feasibilit

29、y of modifying the existing toll free database to make only those 500 and 900 numbers that are assigned to local exchange carriers portable and file a report with the FCC within twelve months of the effective date of the order .” The Commission further asked that this examination consider whether th

30、e technical feasibility could be achieved through modifying the existing toll free database or through another system. The INC accepted this directive and accordingly, submits the following report. In addition, INC sought the expertise of the Network Interconnection/Interoperability Forums (“NIIF”)

31、Networks Interconnection/Architecture Committee (“NIAC”) on those aspects of this report pertaining to interconnection and architecture. Thus, the consensus reflected in this report is that of the INCs and where pertaining to architectures, the NIIFs NIAC (hereinafter the “NIIF”) as well. The NIIF i

32、s also sponsored by the Alliance for Telecommunications Industry Solutions (“ATIS”). 2.0 BACKGROUND ABOUT THE INDUSTRY NUMBERING COMMITTEE- The INC was formed in October, 1993 to provide an open forum to address and resolve industry-wide issues associated with the planning, administration, allocatio

33、n, assignment and use of numbering resources and related dialing considerations for public telecommunications within the North American Numbering Plan (“NANP”) area. The INC reports to the Carrier Liaison Committee of ATIS. INC participation typically includes LECs, interexchange carriers (“IXCs”),

34、competitive local exchange carriers, manufacturers, cellular companies and paging carriers from the US and its territories, Canada and the Caribbean. INC reaches resolution by consensus. Any interested party may submit an issue to INC. However, only issues conforming to the mission of INC will be ac

35、cepted and discussed. Once consensus on an issue before INC is reached, the issue is placed in a status called “initial closure.” Initial closure serves as official notification to the industry that the INC has completed its work. Notice is sent to all INC participants as well as any interested part

36、y on the INC mailing list. It is also posted to the INC website (www.atis.org/atis/clc/inc/inchom.htm). Should any party have concerns about the proposed resolution of an issue, the party can submit contributions to INC during the interval between initial closure and final closure. The INC will cons

37、ider all such contributions. After such consideration, the INC will modify the proposed resolution if consensus is reached to do so based on the contribution. The issue will then move into final closure. Final closure serves as official notification that consensus has been reached for resolution of

38、an issue. In this four and a half years of existence, INC has accepted over 100 issues. It has produced a number of guidelines and recommendations in use by the telecommunications industry today. These consensus documents were developed based on industry input to address the need for a uniform, cons

39、istent manner in the assignment and use of numbering resources. 3.0 ASSUMPTIONS AND THE RAMIFICATIONS OF THOSE ASSUMPTIONS - The INC reviewed the FCC direction in CC Docket 95-116, paragraphs 188 through 198. In order to develop the INCs response, it agreed to the following assumptions and limitatio

40、ns based on the information in the FCC directive. These assumptions and recognized limitations allowed the INC and NIIF participants to start their deliberations, analysis and develop understandings on common ground. It should be noted that if INCs and NIIFs assumptions are correct, then significant

41、 problems/issues are raised because it results in the concept of “limited portability” (i.e., LEC-only portability). 1) Only FCC-regulated LECs are obligated to offer number portability for their own 500 and 900 numbers to the extent technically feasible. 2) The Telecommunications Act of 1996 (herei

42、nafter the “Act”) defines the term “local exchange carrier” as any person that is engaged in the provision of telephone exchange service or exchange access. 3) Commercial Mobile Radio Service (“CMRS”) providers are excluded from the definition of local exchange carriers, and therefore are also exclu

43、ded from the Acts Section 251(b) obligations to provide number portability, unless the Commission ultimately concludes that they should be included in the definition of a LEC. 4) The First Report and Order does not specifically address whether 500 and 900 numbers assigned to CMRS providers shall be

44、portable. Since CMRS providers are not by definition considered to be LECs, it is assumed for the purposes of this report that the 500 and 900 numbers assigned to CMRS providers do not have to be portable. 5) It is assumed that the offering of 500 and 900 services by LECs will increase in the future

45、. Thus, it is also assumed that the volume of such numbers will increase in the future. 6) If it is technically feasible for only LEC-assigned 500 and 900 numbers to be portable, these numbers will be portable only between LECs and not between LECs and other 500 and 900 service providers (IXCs, CMRS

46、, etc.). 7) It is assumed that the type of 500 and 900 service provider (LEC, IXC, CMRS) is determined by its specific business intent, and not by the principal business of the number assignees corporate affiliation. For example, a 500 or 900 number assigned to BellSouth Wireless is considered to be

47、 a CMRS number rather than a LEC number and as such, BellSouth Wireless would not have to make its 500/900 numbers portable. 8) In the current non-portable environment for both 500 and 900 services, number assignment is NXX based; that is, numbers are assigned to 500 and 900 service providers on a N

48、XX basis in blocks of 10,000 numbers consistent with industry assignment guidelines.3With the implementation of portability, number assignment could continue to be NXX based as it is today. However, it may be advantageous to consider number pooling, in which numbers within designated portable NXXs a

49、re made available to all 500 and 900 service providers who participate in 500 and 900 portability. If pooling is mandated by the FCC, then new number assignment guidelines for the pooled environment will need to be developed. The concept of pooling and its relationship to portability are further explained in Section
