• Traffica as a data source for - NetAct Monitor (alarms)- NetAct Reporter (PIs)- NetAct Service Quality Manager (GSM and GPRS: alarms via
Monitor, GSM: PIs)- External systems (raw data via Traffica Database Export)
• Traffica as a surveillance tool- Graphs give a daily summary of network and service situation
and help in benchmarking- User-defined graphs can focus to customer specific services- Alarms indicate problems in the network
• Traffica as a troubleshooting tool- Clear Codes help determine the cause of problems- Traffic News for tracing details of problematic events- Graphs allow drilling Clear Codes and other data values into

Service Specific Monitoring
• In Traffica, Service specific monitoring can be implemented based on, for example
- IMSI or Direction_Number ranges
- Traffic Category, Route Category
- IN indicator- TCH Access Information- Used CGRs
• Any other data in the RTT can be combined to the service definition to allow, for example, drill-down functionality

Monitor Erlangs• Traffica allows you to monitor erlangs toward, for example, different
destinations and route categories (VMS, PSTN): note that Traffica graphs always provide an Erlang approximation, not the exact Erlang value
• Erlang summary is automatically provided with Traffica Summary Report Tool

Monitor Call Lengths
• Since Traffica registers the call start and end times, it is possible to calculate call length with Traffica
• The average call length can be monitored on different network entity levels, and call specific length is visible in Traffic News query output
• Very short calls may give indications of connection quality problems, and can be monitored using for example tailored graphs
