scope:

This standard is part of a series of standards that specifies interface requirements for the interface between Operations Systems (OSs) and Network Elements (NEs). It describes a generic network model needed to develop Operations, Administration, Maintenance, and Provisioning (OAM&P) application message standards for modern telecommunications networks. The term, generic, is used in this document to imply that the managed object classes and their properties described are applicable across different telecommunications technologies (e.g., SONET, ISDN) for the various OAM&P functions defined in ATIS-0300210.The major focus of this standard is alignment with the set of standardization efforts in ITU-T and ISO in the area of Network Management:

• Structure of Management Information - Guidelines for the definition of managed objects [ITU-T Recommendation X.722:1992]. 
• Generic Network Information Model [ITU-T Recommendation M.3100:2005].
• Conformance Statement Proformas for Rec. M.3100, Generic Network Information Model [ITU-T Recommendation M.3101:2005].

System Management functions [ITU-T Recommendation, X.730:1992, X.731:1992, X.733:1992, X.734:1992 and X.735:1992].

The alignment effort consists of: a) Adopting the relevant definitions in ITU-T Recommendation M.3100, where appropriate;

b) Adopting the relevant definitions in ITU-T Recommendation M.3101, where appropriate;

c) Adopting the relevant definitions from the set of System Management Function (SMF) documents, where appropriate; and

d) Addressing in separate documents those aspects of the version 1 model that relate to the PDH transmission hierarchy.

It is the intention of this standard to continue to use and align with Open Systems Interconnection (OSI) management standards, where appropriate.

Purpose

Current telecommunications networks are populated by a large and increasing number of OSs and NEs supplied by different vendors. Both the number and variety of networks and services have grown, creating a diversity of network management needs. This growth has resulted in the proliferation of unique communication interfaces between OSs and NEs. The telecommunications industry stands to benefit from standardization of these interfaces, designed to achieve interoperability between a broad range of OSs and NEs. The purpose of this document is to provide a generic network model for use with this series of standards for telecommunications OAM&P applications.
