Overview
SIGTRAN protocol decoder software is a VoIP testing tool that permits real-time analysis, call trace, capture, and filtering of SS7
and ISDN signaling messages over IP. SIGTRAN uses a new connection oriented transport protocol called Stream Control Transport
Protocol (SCTP). SCTP is at the same level but more efficient at transport than TCP, UDP, or RTP.
Analyzer supports SCTP, M2UA, M3UA, M2PA, SUA, IUA, SIGTRAN protocols. Sigtran is a stack of networking protocols having
Stream Control Transport Protocol (SCTP) and a bunch of user adaptation (UA) layers over it.
SIGTRAN Analyzer Main Features:
- Supports Real-time as well as Off-line analysis
- Uses industry standard NIC Card for interfacing to Ethernet.
- GL Communications' SS7 and SIGTRAN Analyzer simultaneously can permit testing and verification of Signaling Gateways.
- Summary View displays M2UA Class, M2UA Type, M3UA Type and SUA Class, SUA Type, Called and Calling number, SCCP
message type, SSN, INAP information.
- Detailed View displays easy to understand decodes of the user-selected frame.
- Hex Dump View displays the frame information in HEX and ASCII format.
- Statistics View displays call and MSU statistics at any link or entire link set.
- Call Trace View isolates call specific information such as status of each call (active/ completed), duration of completed call, OPC,
DPC, CIC, Called and Calling Party Numbers, and more.
- Search and filtering capabilities for both real-time as well as offline analysis.
- Provides the 'Capture Filter' option to filter M2UA, M2PA, M3UA and SUA frames on the specified ports.
- Application can be installed on multiple computers supporting Windows 2000/XP.

Summary, Detail and Hexdump View
The SIGTRAN Analyzer application is invoked from the main menu of GL Communications' PacketScan™ Analyzer. The
analyzer displays summary, detailed, hex dump, statistics and call trace view in different panes. The summary pane displays
Direction, Frame Number, Time, Length, M2UA Class, M2UA Type, M3UA Type and SUA Class, SUA Type, Called and Calling number,
SCCP message type, SSN, INAP information and various types of SIGTRAN messages for all the frames. The Hex dump view
displays the frame information in HEX and ASCII

Real-time and Off-Line Analysis
Users can capture and analyze SIGTRAN message using real-time analyzer and record all or filtered traffic into a trace file. The
recorded trace file can then be analyzed offline and exported to ASCII file, or printed.

Filtering and Search
SIGTRAN Analyzer includes powerful features such as filtering and search capabilities. It allows to isolate required frames from
all frames in real-time as well as off-line analysis. The application allows filtering according to M2UA Class, M3UA Class, SUA Class,
M2PA, OPC, DPC, SSN, CIC, Called and Calling party number. The Real time filtering can be done using capture filter option for M2UA,
M2PA, M3UA and SUA frames on the specified ports. In addition, the application provides various search criteria to search
appropriate frame.

Call Trace & Statistics View
Call trace defining important call specific parameters like Call ID, Call Status, Call duration, Called Number, Release Cause
etc are displayed.
Statistics is an important feature available in Sigtran analyzer and can be obtained for all frames both in real-time as well as
offline mode. Various statistics can be obtained to study the performance, based on protocol fields and different parameters such
as Use Type (Key/Total/Field) , Statistic type (Frame count, Byte count, Frames/Sec) and patterns like Range List, Wild card.

Enhanced Trace Saving Options
Users can control the captured trace files by saving the trace using different conventions such as trace files with user-defined
prefixes, trace file with date-time prefixes, and slider control to indicate the total number of files, file size, frame count, or time limit.
This feature also allows the captured frames to be saved into a trace file based on the filtering criteria set using display filter feature.

Save/Load All Configuration Settings
Protocol Configuration window provides a consolidated interface for all the important settings required in the analyzer. This
includes various options such as protocol selection, startup options, stream/interface selection, filter/search criteria and so on.
All the configuration settings done in any of these options can be saved to a file, loaded from a configuration file, or user may just
revert to the default values using the default option.
