Generic Requirements for SONET Element Management Systems (EMSs)

Document Number GR-3000
Issue Number 02
Issue Date Nov 1999

    ABSTRACT: Synchronous Optical Network (SONET) transmission equipment provides high-speed data transport. SONET equipment includes network
    elements such as Add/Drop Multiplexers (ADMs); Digital Cross-Connect Systems (DCS's); Element Management Systems (EMS's), which
    manage groupings of network elements; and Network Management Systems (NMS's), which manage groupings of EMS's and possibly network

    This document provides generic requirements for SONET EMS's. The scope of this document includes the definition of management
    architectures relevant to SONET EMS's; functional requirements (grouped into six functional categories - Configuration Management,
    Fault Management, Performance Management, Security Management, Accounting Management, and Common Operations Management); and system
    requirements for the EMS itself. This document does not provide detailed interface specifications for EMS's, but does reference
    relevant interface standards.

    Updates from Issue 1 include addition of a description of the dual transmit ring interconnection method; support for client assigned
    labels; support for inventory discovery, auditing, and resynchronization; and the addition of a new section on accounting requirements.
