The Near Real-time Voice-band Analyzer (VBA) is an analysis tool that can host an arbitrary number of analysis algorithms.
Gaithersburg, Maryland (PRWEB) November 26, 2011
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 Near Real-time Voice-band Analyzer software for monitoring voice band traffic over VoIP, TDM, 2-Wire and wireless networks.
Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, ”The Near Real-time Voice-band Analyzer (VBA) is an analysis tool that can host an arbitrary number of analysis algorithms. Built-in algorithms include ITU-T P.56 Active Voice Level analysis, Line Echo (Hybrid) analysis, and licensed modules include 2-Wire Echo Analysis, Acoustic Echo analysis and Traffic Classifier analysis. Other analysis modules such as ITU-T P.561, P.562, and P.563 can be hosted as plug-ins”.
He added, “The VBA application operates on previously captured files, making it a near-real time (as opposed to a strictly real-time) tool. It supports A-Law, µ-Law, 16-bit PCM (Intel), 16-bit PCM (Motorola) and MS Wave file formats. This package has been designed to work with other GL Communications Inc. tools such as PacketScan™, Call Capture and Analysis, and many other recording tools”.
Mr. Kulkarni further added, “VBA works in conjunction with GL's TDM, Packet, and Wireless non-intrusive capture products:
·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.”
·Near real-time (NRT) 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 (Intel), 16-bit PCM (Motorola) and MS Wave input data formats
·Hosts built-in P.56 Active Voice Level analysis, Hybrid Echo analysis, and other licensed analysis algorithms such as 2-Wire Echo Analysis, Acoustic Echo Analysis and Traffic Classifier analysis
·Allows the grouping of files together into data sets and automatically routes file data to appropriate inputs using user-specified file naming conventions. GL Call Capture and Analysis (CCA) rules are built-in.
·User-selectable analysis output fields
·Native analysis output mode directly compatible with Microsoft® Excel and other readily 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 (T1/E1 lines), 2-Wire Voice/Data Capture and PacketScan™ (VOIP).
·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.
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) are all 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.
