The DeftViewer receives SS7 data from a RTMon server. It then separates the SS7 packets, stores them in a memory array, extracts specific data elements, and puts them in an in-memory database. Filters are applied to the data elements to determine which messages are displayed in the messages window. Filtering When viewing SS7 traffic on a network, the user can become lost in the number of messages scrolling off the screen. In order to control what the user sees, the DeftViewer implements a robust set of filters.
Users can also execute a call trace that displays all messages for a specific call.
Full, Partial, and Hex. Full decodes contain all of the packet information in an easy to read presentation. Partial decode is used to focus in on protocol specific values, while Hex decode is used to see the raw data. The DeftViewer can save SS7 messages into several formats. A decoded message can be saved to a text file, or marked messages can be saved to a DeftCom Data Store file.
