Press Releases: GL Releases GSM A and
GSM Abis Emulation
Gaithersburg, Maryland, USA - August 5, 2009 - GL Communications Inc., announced today the release of GSM-A and GSM-Abis Emulation software for their T1 E1 platforms. In a statement released to the press, Mr. Vijay Kulkarni, CEO of the company said, "GSM is the global standard for mobile voice and data communications. The handheld mobile and the BTS communicate across the radio link. The BTS, BSC, and MSC communicate across Abis and A interfaces within the wireless infrastructure. GL has introduced solutions for the analysis and emulation of Abis and A interfaces. He added, "Our Message Automation & Protocol Simulation (MAPS™) has been enhanced to support GSM A and GSM Abis emulation. MAPS is a powerful Protocol Test platform - supporting a wide range of protocols such as ISDN, SS7, SIP, Megaco, MGCP, and many more."
He added, "MAPS GSM A and Abis interfaces can simulate BSSMAP and DTAP messages and the signaling specification as defined by 3GPP standards. They support testing network elements MSC and BSS, Error tracking, regression testing, conformance testing, load testing/call generation, and generation of high volumes of GSM traffic. The MAPS GSM A and Abis emulation software can run pre-defined test scenarios against GSM A and Abis interface test objects in a controlled & deterministic manner, and supports powerful utilities like Message Editor, Script Editor and Profile Editor which allow new scenarios to be created from existing scenarios using BSSMAP and DTAP messages and parameters".
Mr.Kulkarni, further added, "GL also provides an independent GUI based GSM protocol analyzer and GUI based GSM Abis TRAU protocol analyzer (optional applications) for online 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, STM-1, 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, etc.), and with capacities up to thousands of channels.
GL's VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. 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 excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) are all available.
GL's Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS 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 compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. GL's wirelss 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 intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
