ABSTRACT: This document replaces TR-NWT-001042 and TR-NWT-001042-disk.

This document presents the view of Telcordia on generic requirements for the information model of the system management interface between Management Systems and Synchronous Optical Network (SONET) Network Elements (NEs) using Open System Interconnection (OSI) management services and protocols.

This document provides an overview and usage requirements for the SONET Transport Information Model, referencing object class definitions provided by other Telcordia GRs and standards documents. Additional information is provided to aid developers in understanding, implementing, and using the information model. A companion document, GR-1042-IMD, Generic Requirements for Operations Interfaces Using OSI Tools - Information, Model Details: Synchronous Optical Network (SONET) Transport Information Model, provides detailed definition of object classes using GDMO (Guidelines for the Definition of Managed Objects) templates and ASN.1 (Abstract Syntax Notation - One) supporting productions.

When using GR-1042, you may need to refer to GR-836, GR-836-IMD, and GR-1042-IMD. You may also want to refer to GR-253, GR-828, GR-1114, GR-1230, GR-1253, GR-1400, and SR-NWT-002436; ITU-T G. 774, M.3100, Q.821, Q.822, X.209, X.229, X.721, X.738, X.739, and X.744; ISO 864, 865, 954, 959, 9542, 9595, 9596, 10164, 10165, 10589, 10733, 10737, and 10742; and ANSI T1.119-02, T1.231, and T1.247.
