1、 ATIS-0300118 ATIS Standard on - Next Generation Interconnection Interoperability Forum NGN Reference Document NGN Interconnection ii Foreword The Alliance for Telecommunications Industry Solutions (ATIS) serves the public through improved understanding between carriers, customers, and manufacturers

2、. The Next Generation Interconnection Interoperability Forum (NGIIF) addresses next generation network interconnection and interoperability topics associated with emerging technologies. Specifically, it develops operational procedures that involve the network aspects of architecture, disaster prepar

3、edness, installation, maintenance, management, reliability, routing, security, and testing between network operators. In addition, NGIIF addresses issues that impact the interconnection of existing and next generation networks and facilitate the transition to emerging technologies. The mandatory req

4、uirements are designated by the word shall, and recommendations by the word should. Where both a mandatory requirement and a recommendation are specified for the same criterion, the recommendation represents a goal currently identifiable as having distinct compatibility or performance advantages. Th

5、e word may denotes an optional capability that could augment the standard. The standard is fully functional without the incorporation of this optional capability. Suggestions for improvement of this document are welcome. They should be sent to the Alliance for Telecommunications Industry Solutions,
