SS7 Monitoring
The Signaling Advisor makes it easy for you to start monitoring, even if you don’t know what timeslots or protocols are being used for signaling. The auto configure tool configures the instrument’s receiver to match the bearer and then searches the bearer for signaling links (timeslots that are carrying signaling information). The correct protocol stack will be built based on signaling messages.
If the default protocol stacks do not match the signaling being tested, or a special variant is required, you can quickly change the assigned protocol stack graphically. Figure 1 shows a typical protocol stack.
Figure 1: Protocol Stack configuration
The SS7 Signaling Advisor monitors up to 16 bidirectional bearers and up to 32 duplex signaling links simultaneously (spread across one or more bearers). Each signaling link can carry a different protocol. Monitored data is processed then automatically stored to hard disk.
Post-capture Analysis
All of the capabilities available for real- time analysis are also available for use on previously logged data. The user may perform the same operations as in real time.
Applications
In addition to the default protocol analysis application, it is possible to setup multiple applications for statistical analysis or call traces.
Figure 2 shows a typical real- time measurement setup.
A wide variety of measurement triggers and filters can be set based on almost any interesting variable or event.
