Press Release : GL Enhances
SIGTRAN Protocol Test Suite for Hybrid Networks

Gaithersburg, Maryland, USA – August 10, 2015 - GL Communications Inc., announced today its enhanced SIGTRAN Protocol Test Suite for Hybrid Networks.

Speaking to the press, Mr. Jagdish Vadalia, a Senior Manager for product development of the company said,” MAPS™ is a powerful protocol test simulation platform supporting SIGTRAN (SS7 over IP), and ISDN SIGTRAN (ISDN over IP). Some of the common MAPS™ features supported across all SIGTRAN protocols are: Scripted call generation and call reception, Ready-to-use scripts for quick testing, Script based and protocol independent software architecture and more.”

He explained, “GL's MAPS™ SIGTRANis an advanced protocol simulator/tester for SS7 simulation over IP Networks. MAPS™ SIGTRAN connects to traditional SS7 interface and IP-enabled signaling nodes and then offloads TDM traffic to IP networks. Various traffic types include File, Digits, Tones, FAX, IVR, Dynamic VF, and Voice Quality Testing. MAPS™ can be configured to auto start the traffic over SS7 signaling or manually define traffic at run time. It can simulate ITU-T, UK, and ANSI variants of SS7 signaling stack implemented over M3UA, M2PA, M2UA, and ISUP protocols. It is able to run pre-defined test scenarios against ISUP test objects in a controlled & deterministic manner.  The application supports testing network elements, error tracking, regression testing, load testing/call generation and generation of high volumes of ISUP traffic.

MAPS™ SIGTRAN emulator and MAPS™ SS7 emulator can be combined into one entity to emulate a complete Signaling Gateway. 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 IP, Stream Control Transport Protocol (SCTP) and M3UA (MTP3 User Adaptation Layer).

GL’s MAPS™ ISDN SIGTRAN is an advanced protocol simulator/tester that can simulate a complete ISDN connection from TDM to Signaling Gateway (SG) and Media Gateways Controller (MGC) supporting both PRI ISDN (with traffic) and BRI ISDN interfaces. MAPS™ ISDN SIGTRAN connects to traditional ISDN interfaces and IP-enabled signaling nodes and then offloads TDM traffic to IP networks. Various traffic types include File, Digits, Tones, FAX, IVR, Dynamic VF, and Voice Quality Testing. MAPS™ can be configured to auto start the traffic over SS7 signaling or manually define traffic at run time. ISDN signaling is defined as per 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.

MAPS™ ISDN SIGTRAN emulator and MAPS™ ISDN emulator can be combined into one entity to emulate a complete Signaling Gateway. A Signaling Gateway (SG) on the TDM side connects to standard PRI T1 E1 lines (or BRI) and translates the ISDN messages to SIGTRAN IP format. It supports the same application and call management functions as ISDN but uses two protocol layers on top of IP, Stream Control Transport Protocol (SCTP) and ISDN Q.921-User Adaptation Layer (IUA). The SG talks to a Media Gateway Controller, which in turn performs further routing and signaling decisions within the NGN.”

Mr.Vadalia further added, “The enhanced SIGTRAN protocol test suite now includes enhanced feature rich MAPS™ framework, which includes user-defined statistics, video traffic support, voice quality scores, and commond line interface (CLI)functionalities. Using CLI, all of GUI functionalities can be controlled by various TCL, Python, VBScript, Java, and .Net clients.  In addition, the MAPS™ ISDN SIGTRAN now supports simulation of BRI network interfaces along with PRI interface.”
