Gaithersburg, Maryland, USA - January 11, 2010 - GL Communications Inc. announced today the release of enhanced Voice-Band Analyzer (VBA) - An analysis tool for monitoring voice band traffic over VoIP, TDM, and Wireless networks. Speaking to press, Mr. Jagdish Vadalia Senior Manager said, "Voice-Band Analyzer (VBA) is an analysis tool for monitoring voice band traffic over VoIP, TDM, and Wireless networks. It can host a variety of analysis algorithms. Built-in algorithms include ITU-T P.56 Active Voice Level analysis, Line Echo (Hybrid) analysis, Acoustic Echo analysis, and Traffic Classifier". He added, "Other analysis modules such as ITU-T P.561, P.562, and P.563 can be hosted as plug-ins".

Mr. Vadalia further added, "The VBA application operates on captured files, almost instantaneously, making it near-real time tool. It supports A-Law, µ-Law, 16-bit PCM (Intel), 16-bit PCM (Motorola) and MS Wave file formats. The application has been designed to work with other GL tools such as PacketScan™ (for VoIP), Call Capture and Analysis (for TDM), and GSM, TRAU, and 3G analyzers (for Wireless). VBA can also work with GL's 2-Wire Voice/Data Capture products".

Some Important Features

• Near 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 (Intel), 16-bit PCM (Motorola) and MS Wave input data formats
• Hosts built-in P.56 Active Voice Level analysis, and Hybrid Echo analysis modules. Optionally, Acoustic Echo Analysis and Traffic Classifier analysis modules can be included. Other optional analysis modules are planned.
• Allows the grouping of files together into data sets and automatically routes file data to appropriate inputs using user-specified file naming conventions
• Measurements can be automatically input to a database for centralized applications.
• GL Call Capture and Analysis (CCA) rules are built into VBA.

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.
