GR-3070-CORE, Voice over Packet: NGN Element Management System
(EMS) Generic Requirements
This document describes the functionality and interfaces for a Voice over Packet
(VoP) Element Management System (EMS). The VoP EMS will operate at the
Element Management Layer (EML) of the Telecommunications Management
Network (TMN) architecture. In general, this layer has responsibility for functions
such as control and coordination of VOP Functional Elements (FEs), providing a
gateway to VoP FEs for the Network Management Layer (NML) and higher layers,
and maintenance of statistics and history pertaining to the VoP FEs. More
specifically, this document details a set of ‘generic’ functional requirements on a
VoP EMS to support the management of VoP networks and services. This GR
provides network management generic requirements that are common across the
VoP FEs as well as requirements for network management interfaces to each of the
VoP FEs and the VoP Billing Agent. In addition, this document specifies network
management functional requirements specific to each of the VoP FEs across the
Configuration Management, Fault Management, Performance Management, and
Security Management functional areas. This document is intended to be used as a
functional and interface requirements reference in the design and implementation
of a VoP EMS. Additionally, the document can be employed for testing and
verification of the EMS functions and interfaces. To demonstrate the potential use
of the requirements provided in this document, the GR also details several example
operations scenarios.
