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.

Real-time Analysis
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.
