The Voice Band Analyzer (VBA) is an analysis tool for monitoring the quality of voice band traffic (including hybrid echo) over VoIP, TDM and wireless networks.
Gaithersburg, Maryland (PRWEB) February 07, 2013
GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, announced today the availability of its Software for Network Monitoring of Hybrid Echo and Voice Quality.
Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, "The Voice Band Analyzer (VBA) is an analysis tool for monitoring the quality of voice band traffic (including hybrid echo) over VoIP, TDM and wireless networks. VBA works in conjunction with GL's TDM, Packet, and Wireless non-intrusive capture products, such as T1 and E1 Call Capture and Analysis, VoIP PacketScanTM, and GSM, CDMA, and 3G Call Capture Products. VBA instantly detects voice file captures and with appropriately installed analysis modules, monitors speech levels, noise levels, and hybrid echo. Other analysis modules such as ITU-T P.561, P.562, P.563, fax and modem analysis, and many others can be hosted as plug-ins.”
He added, “The VBA application can also operate on pre-captured files. It supports A-Law, µ-Law, 16-bit PCM (Intel), 16-bit PCM (Motorola) and MS Wave file formats. VBA records its output into two files, the first containing overall channel measurements, and the second containing event records. It produces summary measurements of the captured signals, including active speech levels, noise level; percent time active, DC offset and the like.”
Mr. Kulkarni further added, “The software is directly compatible with many GL's data capture products, including Call Capture and Analysis (T1 E1 lines), 2-Wire Voice/Data Capture and PacketScan™ (VoIP) / MLPPP Analyzer. Also compatible with products of other vendors provided that their file-naming conventions allow grouping of files into sets and associate files with algorithm inputs.”
Some of the Important Features:
·Near real-time (NRT) non-intrusive analysis platform
·Supports 1, 2, 3, and 4-port signal data analysis
·Supports Fax Decode / Demodulation on 2-wire or 4-wire captures
·FaxDD module outputs fax signaling frames in a log file and Fax image in TIF format
·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, Traffic Classifier and Fax analysis
·Allows to implement Psophometric and C-Message signal conditioning before the Active Speech Level analysis; reports C-Message filtered files in dBrnC
·Allows the grouping of files together into data sets and automatically routes file data to appropriate inputs using user
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.
