3.1 These guidelines and procedures should provide the greatest latitude to those providing AMPS based mobile systems, as well as other wireless technologies carriers providing roaming into AMPS based systems, while permitting the effective and efficient management of a finite resource.

3.2 The function of the IRM administrator will be performed by a person(s) or organization so agreed to by the IFAST. The IFAST management is responsible for IRM assignaments if such a body is not agreed to.

3.3 These guidelines do not describe the method by which IRMs are transmitted across and processed by networks. Network interworking arrangements are contained in other standards, documents, or business agreements.

3.4 Participation by all international carriers engaged in providing public correspondence based on wireless medium is strictly voluntary.

The assignment principles defined below allow all international wireless carriers the greatest possible latitude in providing seamless international roaming capabilities in AMPS based systems.

4.1 IRMs are to be assigned, to any wireless carrier meeting the criteria specified in Section 5 of these guideline, to provide roaming in AMPS based networks.

4.2 Upon approval of the application, the IRM adinistrator will initially assign one IRM (country code/network). An applicant must provide customer forecasts to the IRM administrator when more than one code is requested.

4.3 IRMs shall be assigned to permit the most effective and efficient use of a finite resource in order to maximize the existing allocated resource inventory and to defer, as long as practical, the need to request additional MIN resources.

4.4 The IRM administrator will:

• Assign IRMs in a fair, timely and impartial manner to any applicant that meets the criteria for assignment (Section 6).

• Assign IRMs on a first come, first served basis from the available pool.

• Make all assignments based on the procedures in these guidelines.

• Treat sensitive information received from applicants as proprietary and confidential, and not to be shared with non-administrator personnel.

4.5 Information that is requested of applicants in support of an IRM application shall be uniform and kept to a minimum.

4.6 Assigned IRMs should be deployed as soon as possible, but no later than twelve months after assignment. If the assignee can demonstrate that an assigned IRM has not been deployed solely due to delays beyond its control, the time period can be extended for up to 90 days. At the discretion of the administrator, three additional 90-day extensions may be granted.

4.7 Any IRMs assigned to meet the purpose of a "reserve" may be held by the applicant for a period not to exceed 3 years from the date of original assignment at which time the IRM Administrator may reclaim any unused reserve IRMs

4.8 An entity which is denied an IRM assignment or extension under these guidelines has the right to appeal that decision (Section 10).

5.1 The assignment criteria in the following paragraphs should be considered by a potential IRM applicant before submitting an IRM application and will be used by the IFAST in reviewing and processing an IRM application.

5.2 International Roaming MINs Network Codes will be assigned to all AMPS based cellular networks that are located in countries which are outside of the North American Numbering Plan area countries and have desire to provide roaming with countries included in NANP. All international wireless networks outside of the NANP area countries, including Global Mobile Satellite Service networks (which are based on intersystem operations for roaming which are not compatible with roaming protocol specified in all versions of the EIA/TIA/ANSI 41 standards, and have desire to provide roaming in AMPS based networks throughout the world with mutimode handsets and appropriate protocol conversion functions for mobility management signaling messages) are eligible for the assignment of IRMs.

Entities requesting IRMs assignments and entities already assigned one or more IRMs shall comply with the following:

6.1 IRM Netwok Code applicants and assignees must meet all conditions specified in these guidelines. Copies of the guidelines may be obtained from the IRM network Code administrator.

6.2 Applicants must apply in writing to the IRM Network Code assignment administrator once their petition has been approved by the IFAST Forum.

These guidelines make no attempt to "Grandfather" any previous assignments of MINs or IRM allocations. Use of all assigned resources on a going forward basis shall be consistent with these guidelines.

It may be necessary to modify the guidelines periodically to meet changing and unforeseen circumstances. The need for guidelines modification may be identified by the administrator, any entity in the international wireless telecommunications sector or the IFAST Forum. When need for modification is identified by other than the forum, the identifying entity will submit the modification issue to the forum. The forum will coordinate the modification process. Questions or concerns regarding the maintenance of the guidelines may be directed to:
