Speaking to the media, Mr. Jagadish Vadalia, a Senior Manager, Product Development at GL said, “The Near Real-Time Voice-Band Analyzer (VBA) is an analysis tool for monitoring the quality of voice band traffic over VoIP, TDM, and Wireless networks. VBA works in conjunction with GL's TDM, Packet, and Wireless non-intrusive capture products”. He added, “VBA instantly detects voice file captures and with appropriately installed analysis modules monitors speech levels, noise levels, line echo, and acoustic echo”.
Mr. Vadalia further added, “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 and will be available soon. The VBA application can also operate on previously captured files. It supports on A-Law, µ-Law, 16-bit linear PCM, and Wave file formats”.
Main features:
• Near real-time non-intrusive analysis platform;
• Supports 1-, 2-, 3-, and 4-port signal data analysis;
• The VBA includes manual, batch, and automatic processing modes;
• Supports A-Law, µ-Law, 16-bit linear PCM, and WAV input data from files;
• Hosts built-in P.56 Active Voice Level analysis, Hybrid Echo analysis, and Acoustic Echo Analysis and optional analysis algorithms as plug-ins;
• Can group files together into file sets and routes file data to appropriate inputs using user-specified file naming conventions. GL Call Capture and Analysis (CCA) rules are built-in.
Modes of Processing
The Voice-Band Analyzer operates in three fundamental modes:
• Manual;
• Batch;
• Automatic.
Modes of operation
The Voice-Band Analyzer GUI supports various modes of operation while analyzing voice band for speech level, line echo, and acoustic echo.
• Link Emulation;
• Active Speech Level;
• Line Echo Model Configuration;
• Acoustic Echo Model Configuration.
