EVM and MMS/E served by Mitec Group

Mitec Group is responsible for support and service of Event Manager (EVM) and MMS/E, originally from Ericsson.

Mitec Group has assumed ownership and responsibility of both solutions due to the reputation and track record Mitec enjoys in the market for network management. The shift in responsibility provides an avenue to strengthen the Ericsson product portfolio in the area of network management.

Both solutions can be obtained from the traditional Ericsson channels.

The Event Manager (EVM) provides flexible and scalable management solutions based on industry standards and protocols. The Event Manager is available for a market leading management platform, the Hewlett-Packard OpenView? Network Node Manager, making it easy to use and integrate with third-party products. For enterprises and service providers this results in lower cost of operation, enhanced performance and increased network availability.

The Event Manager combines complex functionality with high usability, and provides tools that use a graphical user interface (GUI) for the visualization and monitoring of MD110 PBX networks, plus monitoring of D.N.A. Application Suite and OneBox services from one interface.

• The Event Manager is integrated with the Hewlett-Packard OpenView Network Node Manager, and thereby creates a single point of management.
• Familiar Windows interface provides simplified interaction and an integrated approach to network management.
• Open interfaces enable other applications to run in the same environment
• Standard platform enables easy integration with existing management infrastructures

• Easy Network Mapping using auto-discovery and synchronization of found nodes
• Possibility to manage non-Ericsson node types in a standardized environment
• Unique symbols for Ericsson network elements for easy identification and status overview
• Alarm history log for storing important alarm and status events
• Color-coded node status according to HP OpenView?s standard color codes
• Logon to nodes using telnet connection or other 3rd party management applications
• Node-to-node connection wizard for increased readability
• MIB browser for thorough inspection off all discovered network elements
• Other D.N.A. applications launched from node icon

The Event Manager uses HP OpenView?s discovery mechanisms to explore the network. The discovered nodes are polled and data is collected to provide an accurate view of the network topology.

• EVM nodes only, suitable for large-scale networks
• EVM nodes and other network elements in smaller networks, or where managing several node types from the same management interface is a requirement

The Event Manager will further explore any MD110, D.N.A. or OneBox nodes, and create individual submaps for each node with icon representations for each element. These submaps can then be joined together to provide a hierarchy of maps from global to node level. All alarms are reported up through the different topology layers as they occur. By focusing down to node level, the alarm log can be examined to determine the cause of the events.

Hierarchies of submaps are used to logically group and represent topological components.

By double-clicking on a selected symbol the user can drill down sub-maps and easily locate the component of interest.

The network level contains an overview of the nodes that form the network and the connections between them. In addition, users can configure this submap to group selected nodes into regions, for example, and hence have a better overview of the monitored network. These regions in turn contain the nodes that form a regional sub-network and the connections between them. This is called the sub-network level.

Hierarchies typically have four levels:

• The network level
• The sub-network level
• The node level
• The connection level

The Event Manager is integrated with the HP OpenView Network Node Manager, and is responsible for discovering the node level details. A dedicated connection wizard is available for creating connections between interfaces found at the node level, enabling easy-to-understand visualization of connections between node elements such as trunks.

Faults and configuration changes are propagated upwards in the map hierarchy and each icon is color coded to reflect alarm status. A common alarm log is also maintained which can be used to determine the cause of the alarms. The network nodes are also polled for status changes with configurable intervals. Since Event Manager is based on an open management platform, it is possible to make use of third-party applications and to create specific customer adaptations to further enhance management functionality.

Severities

HP OpenView?s color codes are used to reflect the status of the node and its components. This status information is propagated upwards in the map hierarchy. Node Manager also supports HP OpenView?s Event Correlation System that reduces the overflow of events into the system, improving overall performance.

The network nodes are polled at configurable time intervals to detect status and configuration changes.

Alarm log

The HP OpenView Alarm Browser is used for viewing alarm events. This also includes alarms received from nodes managed by EVM

Active MD110 Alarms

The EVM Alarm Handling Application is used to get more detailed information about active MD110 alarms, and notes can be added for each alarm. The EVM Alarm Handling Application also integrates with DynaText, and can display further explanation for selected MD110 alarms.

Launching External Applications

In addition to alarm reporting functions, Event Manager also supports the direct launching of external applications towards the selected network element. In this way, an MD110 node can be selected and sub-windows for the following applications be opened directly towards the network element:

• DynaText

• D.N.A. Extension Manager (EMG)

• D.N.A. Numbering Plan Manager (NPM)

• D.N.A. Performance Data Manager (PDM)

• D.N.A. Performance Presentation Manager (PPM)

• D.N.A. Routing Presentation Manager (RPM)

• WinFIOL

• Telnet

• Procomm
