Scope

This standard is part of a series of standards that specifies interface requirements between Operations Systems (OSs) and Network Elements (NEs). It describes a set of Performance Management functional area services and associated information model for Operations, Administration, Maintenance, and Provisioning (OAM&P) applications for DS1 and DS3 signals.

It is the intention of this standard to use and align with relevant OSI and ITU-T system management standards when they are available.

The alignment effort consists of adopting the relevant definitions in ITU-T Recommendation Q.822.

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 management needs. This growth has resulted in the proliferation of unique communication interfaces between OSs and NEs. The telecommunication 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 set of application messages for the support of OAM&P Performance Management functions.

Application

This standard supports the Transaction-Oriented class of OAM&P applications specified in ANSI T1.208 by describing how the communication functions in ANSI T1.208 are used to support the Performance Management functions in ANSI T1.210. These messages require the managed objects defined in ANSI T1.240 and ITU-T Recommendation Q.822.

The minimum service and protocol requirements at the Session and Presentation Layers, and the supporting Application Service Elements (ASEs) for two classes of OAM&P applications at the Application Layer, are defined in ANSI T1.208.
