MetarWork NMS & OSS Page 3 Features and Functionalities of NMS INMS LAYER 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. EMS LAYER IEMS EMS Sub-Network Management System (SNMS) EMS This manages a sub-net, so it usually has an INMS above it, therefore a northbound interface (NBIF) needs to be implemented. SONET/ CDMA/ IP/ATM Soft Integrated Element Management System (IEMS) SDH GSM/3G Switch Managing the NE’s directly or through vendor’s EMS, this also requires a northbound interface. NE LAYER 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.

A MD POOL DB SNMP CORBA Q3 RS232 TCP/IP customized interface, to be connected to an Siemens Ericsson … Alcatel Huawei Lucent NEC Fujitsu … external system, also supports all major protocols. 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 “disaster recovery” measure in case the entire Main Centre is debilitated. * All brand names and trademarks are the property of their respective owners.

References Regional Presence The map on the right illustrates our strong presence in China. The areas highlighted yellow denote the provincial fixed-line networks that employ MetarNet’s NMS solutions. With its explosive growth in demand for bandwidth, China’s telecom networks are often large-scale (composed of several thousand NE’s), and involve multiple (10+) vendors. The widespread use of MetarNet’s products in China, and elsewhere in Asia, is a strong testament to our ability to handle complex, heterogeneous networks.
