18、commitment. 7.2 Administrator Responsibility International Inbound NPA Assignment Guidelines ATIS-0300049 September 30, 2011 Page 11 of 17 _ The NANP resource administrator will contact any resource assignee(s) identified as not having returned to the administrator for reassignment of any NANP resou
19、rce: - Assigned, but no longer in use by the assignee(s), - Assigned to a service no longer offered, - Assigned, but not activated by the INC-established date, or - Assigned but not used in conformance with the appropriate assignment guidelines. The administrator will seek clarification from the ass
20、ignee(s) regarding the alleged non-use or misuse. If the assignee(s) provides an explanation satisfactory to the administrator, and in conformance with the assignment guidelines the resource will remain assigned. If no satisfactory explanation is provided, the administrator will request a letter fro
21、m the assignee(s) returning the assigned resource. If a direct contact can not be made with the assignee(s) to effect the above process a registered letter will be sent to the assignee(s) address of record requesting that they contact the administrator within 30 days regarding the alleged resource n
22、on-use or misuse. If the letter is returned as non-delivered the administrative advise the INC that the resource will be made available for reassignment following the established idle period, if any unless the INC advises otherwise within 30 days. The NANP resource administrator will refer to the IN
23、C for resolution any instance where a NANP-assigned resource has not been returned for reassignment by the assignee if: - The resource has not been activated by the INC established date. - A previously activated resource is not now in use. - An activated resource is not being used in accordance with
24、 the appropriate assignment guidelines. If a resource is not activated by the INC-established date and the administrator determines, by discussion with the resource assignee(s), that the reason for the non-activation is not within the control of the assignee(s), the administrator may extend the INC-
25、established activation date by up to 90 days. The NANP resource administrator will receive, process and refer to the INC for resolution any application from resource assignees for an extension on an INC-established NANP resource activation date when the: - Activation has not occurred within the 90 d
26、ay extension, - Administrator believes that the activation has not occurred due to reason within the assignees control, or - Assignee requests an extension in excess of 90 days. International Inbound NPA Assignment Guidelines ATIS-0300049 September 30, 2011 Page 12 of 17 _ Referral to INC will inclu

28、Accept all referrals of alleged non-use or misuse of NANP resources from the resource administrator or any other entity - Investigate the referral, - Review referrals in the context of existing assignment guidelines, - Attempt to resolve the referral, and - Direct the resource administrator regardin
29、g the action, if any, to be taken. Absent a consensus resolution of the referral or non compliance to the resolution by the resource assignee, INC shall refer the case to the appropriate regulatory authority for resolution. 8.0 Code Conservation Assignment of INT/NPA/NXX numbering resources is under
30、taken with the following conservation objectives: a) to efficiently and effectively manage a limited resource which is further encumbered by a technical limitation which only allows the translation of six digits and effectively limits the assignment of these NXXs to the NX level at this time (see Se
31、ctions 2.6 and 4.4). b) to delay the exhaust of the INT/NPA/NXX code resource. 8.1 Ongoing code administration practices which foster conservation, including annual audits and surveys, will be used to assure that the assignment criteria identified in Section 4, and code holder responsibilities ident
32、ified in Section 5, are being met. Appendix A provides a description of the Audit Process.

33、ing: 9.1 INT/NPA/NXX code assignments will be tracked and monitored, projected exhaust will be determined and relief planning activities will be initiated within the industry. 9.2 When the initially assigned 456 NPA code approaches exhaust it is planned that the code administrator will examine the a
34、vailable options and in consultation with the industry, assign another NPA code if appropriate. 10.0 Maintenance of Guidelines 10.1 It may be necessary to modify these assignment guidelines periodically to meet changing circumstances.
