Near Real-time Voice-band Analyzer

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 Nearly Real-time Voice-band Analyzer software for monitoring voice band traffic over VoIP (Voice over Internet Protocol), TDM, 2-Wire and wireless networks.

He added, "The VBA application operates on before captured files, making it a nearly-real time tool. It supports A-Law, µ-Law, 16-bit PCM, 16-bit PCM and MS Wave file formats. This package has been designed to work with other GL Communications Inc. tools just as PacketScan™, Call Capture and Analysis, and many other recording tools".

·VBA with GL's TDM T1 E1 Call Capture and Analysis, or ·VBA with GL's VoIP PacketScan™ ·VBA with GL's GSM, CDMA, and 3G Call Capture Products ·VBA with GL's 2-Wire Voice/Data Capture Products."

·Nearly real-time non-intrusive analysis platform. ·Supports 1, 2, 3, and 4-port signal data analysis ·Manual, batch, and automatic processing modes. ·Accepts A-Law, µ-Law, 16-bit PCM, 16-bit PCM and MS Wave input data formats ·Hosts built-in P.56 Active Voice Level analysis, Hybrid Echo analysis, and other licensed analysis algorithms just as 2-Wire Echo Analysis, Acoustic Echo Analysis and Traffic Classifier analysis ·Allows the grouping of files at the same time into data sets and automatically routes file data to appropriate inputs using user-specified file naming conventions. GL Call Capture and Analysis rules are built-in. ·User-selectable analysis output fields ·Native analysis output mode directly compatible with Microsoft® Excel and other gladly available analysis tools. ·Database interfaces available on request. ·Source signal file management options ·Directly compatible with many GL data capture products, including Call Capture and Analysis, 2-Wire Voice/Data Capture and PacketScan™. ·Compatible with products of other vendors provided only that their file-naming conventions could be used to group files into sets and associate files with algorithm inputs.

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 VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types just as frames, packets, voice files, digits, video, tones, noise, and fax. Nearly 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 as well 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 product line complements all of GL's products. Using ITU-standard algorithms, GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks are all available.

GL's Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE (Long Term Evolution, latest standard in the mobile network technology) networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.

The broadest range of simulation

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 just 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.

Wide variety of communications facilities

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 nearly 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.
