GL Communications Inc announced today, enhancements to their protocol analyzer and scripted client server products, with the release of T1 E1 Analyzer Software Version 5.20. Briefing the news to the press, Mr. Vijay Kulkarni, CEO of the company said, “Our T1 E1 Analysis suite of products provides comprehensive analysis and emulation capabilities for voiceband analysis and signaling protocol analysis. The additions now include a host of significant enhancements to protocol analyzers: GSM Protocol Analyzer, Trau Protocol & Trau Traffic Playback, and SS7 Protocol Analyzer. Also a new feature to simulate acoustic echo has been added to scripted client server software”.

Enhancements introduced to Protocol Analyzers:

  • GSM Protocol Analyzer

Our GSM real-time and offline protocol analyzer now supports decoding of proprietary 'Mobis' Interface (Motorola equivalent of the GSM A-bis interface). This includes messages between BSC (Base Site Controller) - BTS (Base Transceiver Station) and BSC (Base Site Controller) - PCU (Packet Controller Unit).

•TRAU Protocol Analyzer & TRAU Traffic Playback
The Physical Link layer parameters in Statistics has been changed to include Device 3, Start/End Subchannels, Start/End Timeslots, Timestamp, Errors Code, Total sub channels and Timeslots per sub channel used.

•SS7 Protocol Analyzer
Our SS7 Protocol Analyzer is enhanced to support decoding of INAP CS2 (Capability Set 2) as per INAP CS2: ITU recommendation Q.1228, and INAP CS2 (ETSI): EN 301 140-1 Specification.

Auto-connect Network Management messages are now available in the summary view, statistics, filtering, and search capabilities.

Enhancements introduced to the Window Client Server Application:
•Acoustic Echo Path Simulation using Dynamic DSP Operations
The application has been enhanced with Scripted DSP commands that provide the ability to specify a sequence of digital signal processing steps to be performed on incoming and/or outgoing timeslots. The WCS DSP Operation module allows real-time as well as offline testing using DSP commands to perform functions such as Amplification/Attenuation, Delay, Filter, File Tx/Rx, Logical Operations etc.

Complex echo paths and complex block diagram operations can be easily simulated using the following functions: sum, invert, filter, delay, amplify, attenuate, bxor, bor, brev, bnot, band, infile, outfile, white noise, tone, dual tone, phase shift, dtmf digits, mf digits, mfcr2 digits, power monitor, signaling bits monitor, const, bytes, and many other operators.
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 products generate / analyze thousands of calls simultaneously with traffic types such as 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 a Software Ethernet Testing capability that checks frame transport and throughput parameters of Ethernet and IP networks.

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, Landline, etc.) 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, RS422 / RS530, 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.
