Comarch Fault Management is the ultimate solution to ongoing fault issues within an operator's networks. The system monitors all existing elements of the network, displays and efficiently tracks alarms.

This allows users to manage potentially debilitating network problems quickly and effectively. Its flexible and extensive range of features assists operators in detecting and solving issues that are at the root of network faults.

Main components of Comarch Fault Management solution are:

• Object Repository – main database storing all alarm related data for use by other components
• Correlation Service – carries out filtration and intelligent correlation of events detected in the network
• Mediation Platform – responsible for events collection and pre-filtration task, gathers events from the external devices and performs format translation
• Comarch OSS Console – provides unified GUI interface;
• System Repository and Configuration – supervises and controls all the components and subsystems, responsible for storing configuration of all subsystems and for verifying integrity of the system
• Authentication Service – authenticates users and provides users and privileges management
• Notification and Escalation Service – handles notifications and escalations
• Reporting Service – generates charts and reports

Comarch Fault Management enables users to fully configure the way alarms are processed. This speeds up identification of failures and allows users to allocate tasks according to internal company processes. All alarms are collected, processed and displayed in real-time. Alarm information is automatically updated as soon as new alarms arrive, providing users with a dynamically changing view that accurately reflects the actual state of the network. Detailed information on alarms within a selected location can be immediately displayed by opening the alarm manager from the context menu. Appropriate filters are applied automatically in order to allow fast, context-based navigation which strongly reduces alarm processing time.

Comarch Fault Management provides a sophisticated alarm visualization interface. Apart from visualizing the list of alarms it is possible to use maps in order to visualize the status of the network infrastructure. The system supplies geographical, logical and hierarchical visualization as well as a floor plan view of the network and its faulty elements through imported AutoCAD DXF files. This detailed view enables users to obtain the most complete information about the exact location of faulty elements that can be further passed onto other team members in order to optimize repair times.

Comarch Fault Management uses Reasoning Engine – Comarch's proprietary correlation module – in order to automate the processing of alarm events. This rule-based event management application is equipped with internal rule definition language, which is seamlessly configurable using the Comarch OSS Suite console user interface. The idea behind the use of the correlation engine is to speedup event management in order to quickly identify the root of existing alarms. By defining reasoning scenarios users can transfer the corporate infrastructure know-how to the Comarch Fault Management system in order to obtain real and meaningful alarms pointing out the real cause of the problem.

Comarch Fault Management provides users with a set of standard functions to be used during the definition of scenarios in order to retrieve additional data during execution of correlation rules:

• Notifications
• Event generators
• Counters
• Database connections and queries
• FTP/Telnet/SSH operations
• Remote command execution
