GL Communications Inc. conveyed today the availability of its product MAPS™ SIGTRAN ISDN Protocol Emulator – Scripted SIGTRAN ISDN Over IP Emulation.

MAPS(TM) ISDN SIGTRAN Web Architecture

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.

GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, conveyed today the availability of its product MAPS™ SIGTRAN ISDN Protocol Emulator – Scripted SIGTRAN ISDN Over IP Emulation.

Speaking to media persons, Mr. Jagdish Vadalia Senior Manager of the company said, ” 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.”

He added, ”MAPS™ SIGTRAN ISDN over IP also incorporates the flexibility to modify ISDN call parameters & message contents (arbitrary manipulation of messages, information elements and message sequence on the different protocols). This flexibility ensures that the MAPS™ SIGTRAN ISDN over IP communicates with the system under test. It supports powerful utilities like Message Editor and Script Editor which allows creating new scenarios or modifying the existing scenarios using ISDN messages and parameters.”

Mr. Vadalia further added, “GL also provides a GUI based SIGTRAN Analyzer for on-line capture and decode of the signaling in real-time both during tests and as a stand-alone tracer for live systems.”

About GL Communications Inc.,

Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.

GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, LTE, etc.), and with capacities up to thousands of channels. Our newest products provide astonishing capacity and capture capability up to and including gigabit speeds.

GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax. Almost all codecs are supported including G.711, G.729, AMR, EVRC-A,B,C, GSM, iSAC, and many more. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.

GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) is available.

GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.

GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic echo. GL’s compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.

GL’s wireless VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.

GL’s Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.

GL’s Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
