Features and Functionalities of NMS

                                                 Scope
                  INMS
                                                 In a large network, there can be several layers of
                                                 NMS. Metarnet can provide solutions for all those
 SNMS LAYER                                      layers:
                  SNMS                METARNET   Integrated Network Management System (INMS)
                                                 This is the management system at the top level.

                                                 This manages a sub-net, so it usually has an INMS
                                                 above it, therefore a northbound interface (NBIF)
                                                 needs to be implemented.

Functions
Metarnet NMS supports all the standard network
management functions:

   -    Topology management
   -    Alarm/Fault Management
   -    Performance Management
   -    Inventory Management
   -    Configuration Management
   -    System/Security Management
   -    Call Data Recording
   -    Traffic Data Analysis, etc


                                                 Topology Management
                                                 Integrated with cutting-edge Geographical
                                                 Information Systems (GIS), exact locations of
                                                 network equipment can be pinpointed. High
                                                 resolution maps allow users multiple zooming to
                                                 display geographical details accurately (up to
                                                 1:50,000).

                                                 The GIS can also be combined with other modules,
                                                 such as alarm management, so that equipment with
                                                 alarms can be shown blinking on the map.
Alarm/Fault Management

This module supports all major alarm/fault
functionalities, such as real-time alarm reporting,
alarm filtering, alarm masking, and severity
assignment, among others. Reporting of alarms can
be customized into various forms such as pie charts,
bar charts, graphs and tables.

A sophisticated Root Cause Analysis (RCA) system
uses artificial intelligence to filter out a large
number of alarms and narrow down to a few root
causes, thus saving the operator substantial
trouble-shooting time.

                                                       Performance Management

                                                       Performance monitoring data can be collected in
                                                       intervals as short as 15 minutes. Just like for
                                                       alarms, PM counts reporting can be customized into
                                                       various graphical representations.


                                                       PM thresholds can be set for each individual PM
                                                       attribute, so that when the PM count exceeds the
                                                       threshold, an alarm is raised.

                                                       User can also define their own PM attributes based
                                                       on existing attributes.


Configuration Management


This module provides comprehensive information on
network configuration such as network organization
architecture, resource management, traffic
distribution analysis, equipment room layout, and
equipment panel view.

Highly detailed and photo-realistic user interface
gives operators excellent look-and-feel, thus
allowing easy, intuitive provisioning of equipment
and circuits.

Hardware Architecture

The NMS can run on various hardware platforms,
including SUN, HP, IBM, SGI, and Linux* for smaller
systems. In a typical configuration, most hardware
are located at a Main NMS Centre, interconnected
through a high-speed Ethernet LAN. Network
management data are stored in a disk array, with
long-term back-up storage provided by a tape
library. PC’s are used as client terminals, and a
router connects the Main Centre to the operator’s
Digital Circuit Network (DCN) to communicate with
remote sites.

A high level of redundancy is achieved with extra
servers on hot standby, along with High Availability
(HA) software. For extra precaution, a backup site
                                                                                                                          Remote           Remote               Backup
can be implemented. The backup site serves as a
                                                                                                                           Site             Site                 Site

Centre is debilitated.

 With the imminent deployment of 3G services in                                 While our Unix-based NMS offers a powerful,
 many countries in the region, a comprehensive                                  comprehensive solution for large, heterogeneous
 network management solution for 3G networks is in                              networks, there is always a demand for smaller
 strong demand.                                                                 scaled, simpler network managements systems.


 MetarNet’s 3G NMS is designed based on the                                     Developed on Linux Redhat AS4*, our Linux-based
 specific requirements of 3G network management,                                NMS can monitor and manage small to medium sized
 features in 3G services, and the implementation                                Access and SDH networks (< 1000 nodes), with a
