The sequence diagram feature is a powerful graphical call flow analysis tool integrated in the PALLADION NGN software suite. Call flow diagrams are easily browsable, the detail level of contained text information can be added and removed, and each protocol message will be opened automatically on mouse-over. Multiple calls can be shown at the same time, and even compare individual protocol messages with feature syntax highlighting, for better readability. Every call is displayed with in-depth media quality information, both from PALLADION and from the end devices.
