5 Powerful NgN Signaling Analysis Capabilities detailed information on every call NgN Analysis System provides you with comprehensive information on every call monitored, covering both calls in progress and calls long terminated. It correlates and stores the signaling messages associated with a call into a Call Flow Record (CFR). It also generates a Service Measurement Record (SMR) for each call, containing performance and quality of service (QoS) measurements. You can aggregate this data by customer, network element or service to provide essential information that helps to support service level agreements, network performance management and network planning. Troubleshooting is fast, easy and effective. You can select an individual call flow record from the list displayed to analyze it in detail. Abnormally released calls are highlighted in red to help you identify problems quickly. Different filters can be set to isolate calls of interest, such as calls to a specific area code or number Extensive SS7 link and trunk status reports provide useful information on hybrid network signaling issues. These include link status, current and average call hold times, continuity check failures, and blocked trunks reports. Network-wide signaling analysis for total network assurance

6 Agilent NgN Analysis System with Service Level Manager service assurance with proactive service and performance management Additional functionality is provided by NgN Service Level Manager, an integrated application providing proactive service/performance analysis and real time SLA monitoring and reporting. This valuable service assurance tool gives you an important competitive advantage, enabling you to differentiate your services through measurable and manageable SLAs. Extensive Service Level Monitoring, Alarming and Reporting The NgN Service Level Manager combines and correlates the available service measurement records by customer, network or network element.

8 Agilent NgN Analysis System in action Agilent NgN Analysis System is the only solution available that offers real time VoP surveillance. It provides detailed information on every call monitored, for calls in progress as well as historic calls, correlating and storing the signaling messages relating to each call in a Call Flow Record (CFR). It also generates Service Measurement Records (SMRs) that contain performance and quality of service (QoS) information for each call. This information enables detailed analysis and troubleshooting even for calls long terminated. Aggregation of this data by customer, network element or service provides vital information for service level agreements, network performance and network planning. Example 1: Detailed signaling analysis and troubleshooting The NgN Analysis System presents time-correlated VoP and SS7 signaling messages and timing information in a graphical call flow diagram. Clicking on individual signal messages displays the complete decoded signal message in a separate window for detailed analysis. The call voice path display indicates the IP end points involved and the IP-RTP quality parameters such as packet loss and jitter.

9 Example 2: Resolving signaling problems With just one mouse click, the NgN Analysis System produces a fullydocumented HTML record of an entire call. The record includes the message sequence chart, including the complete protocol decode of all the messages contained in the call. The record can be used with vendors or interconnected service providers to help resolve problems and ultimately to improve customer satisfaction. Example 3: Service Level Monitoring, Alarming and Reporting Automated SLA report generation on delivered QoS and SLA compliance can be made available for viewing on a secure Web page with any Web browser. These customizable reports include service performance, asset utilization, diagnostics reports and planning summary reports The NgN Analysis System s network wide surveillance and proactive troubleshooting combined with service and performance management provides you with all the information you need for service level management, performance monitoring and network planning.
