GL Communications has introduced enhanced SIGTRAN Protocol Analysis and Simulation tools. The SIGTRAN protocols are an extension of the SS7 protocol family, but carried over IP. A Signaling Gateway (SG) translates the SS7 TDM layers to SIGTRAN IP format. It supports the same application and call management functions as SS7 but uses two protocol layers on top of Internet Protocol (IP): Stream Control Transport Protocol (SCTP) and M3UA MTP3 User Adaptation Layer.

M3UA enables SS7 protocol's User Parts (e.g. ISUP, SCCP and TUP) to run over IP instead of TDM lines.

The SIGTRAN Protocol Test Suite comprises of SIGTRAN Protocol Analyser, SIGTRAN Protocol Emulation over IP, SIGTRAN ISDN over IP Emulation and BICC Protocol over IP Emulation.

The 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. The Analyser supports SCTP, M2UA, M3UA, M2PA, SUA, IUA, BICC, INAP, CAMEL, ICMP, MAP, TUP, TCAP, SCCP and more. The Analyser is an optional application and requires PacketScan - All IP Analyser license to invoke.

The Message Automation & Protocol Simulation (MAPS) is a powerful protocol test simulation platform supporting a wide ranging protocols such as SIGTRAN (SS7 over IP), SS7 over TDM (T1 E1), ISDN over TDM (T1 E1), GSM-A & GSM-Abis over TDM, Megaco, SIP, and MGCP over IP.

GL's MAPS SIGTRAN is an advanced protocol simulator/tester for SS7 simulation over IP Networks. It can simulate ISUP signalling specification as defined by ITU-T standards. The application supports testing network elements, error tracking, regression testing, load testing/call generation and generation of high volumes of ISUP traffic. MAPS SIGTRAN functionality covers the ITU and ANSI variant of SS7 implementing M3UA, and ISUP protocols. It is able to run pre-defined test scenarios against ISUP test objects in a controlled & deterministic manner.

MAPS SIGTRAN Emulator and MAPS SS7 Emulator can be combined into one entity to emulate a complete Signaling Gateway. M3UA, M2UA, and M2PA transports are easily supported.

GL’s MAPS SIGTRAN ISDN over IP is an advanced protocol simulator/tester used for ISDN simulation over IP. The tester can simulate a complete ISDN connection SG to MGC, where ISDN signaling is defined by the ITU-T Q.921 / Q.931 standards. It is a powerful tool that can be used to perform detailed testing of ISDN protocol messages over IP, and offers a complete solution for testing, troubleshooting, and maintenance of devices and networks implementing PRI ISDN.
