SIGTRAN Protocol Analyzer
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.
GL's SIGTRAN analysis is an optional module available with PacketScan analyzer (PKV100) with additional licensing (PKV105).
In addition, GL provides emulation tools that further help in emulating SS7 and ISDN protocols over IP.
SIGTRAN Analyzer Main Features:
- Supports Real-time as well as Off-line analysis
- Uses industry standard NIC Card for interfacing to Ethernet.
- The SS7 and SIGTRAN Analyzer simultaneously can permit testing and verification of Signaling Gateways.
- Displays Summary, Detail, Hex-dump, Statistics, and Call Trace Views, the contents of this view can also be copied to clipboard.
- 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 raw frame data as hexadecimal and ASCII octet dump, the contents of this view can also be copied to clipboard.
- 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.
- Any protocol field can be added to the summary view, filtering, and search features providing users more flexibility to monitor required protocol fields.
- Application can be installed on multiple computers supporting Windows 2000/XP.
The supported protocol standards in Sigtran analyzer are SigTran ITU, SigTran ETSI, SigTran ANSI.

Summary, Detail and Hexdump View
The SIGTRAN Analyzer application is invoked from the main menu of GL's 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 User 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. Any protocol field can be added to the summary view,
filtering, and search features from this GUI providing the users more flexibility to monitor required protocol fields. 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.
