GL Communications Inc. announced today its enhanced Near Real-time Voice-band Analyzer, an analysis tool for monitoring the quality of voice-band traffic over TDM, VoIP, and wireless networks.
Jagdish Vadalia, a senior manager for product development of the company, said, “The Near Real-time Voice-band Analyzer (VBA) is a versatile analysis tool that helps monitoring voice-band traffic over variety of networks including VoIP, TDM, 2-Wire, and Wireless. It can host an arbitrary number of analysis algorithms.”
Built-in algorithms, he said, include ITU-T P.56 Active Voice Level analysis, and Line Echo (Hybrid) analysis; licensed modules include 2-Wire Echo Analysis, Traffic Classifier, and Fax 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), MS Wave, G.726 (40 kb/s, 32 kb/s, 24 kb/s, and 16 kb/s), and G.722 (64 kb/s) 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.”
Vadalia further added, “The optional VBA FaxScan module can be used to analyze both 2-wire and 4-wire voice-band captures for fax traffic and output fax signaling frames in a log file and fax image in TIFF format.
“VBA works in conjunction with GL’s TDM, Packet, and Wireless nonintrusive capture products: VBA with GL’s TDM T1 E1 Call Capture and Analysis, orVBA with GL’s VoIP PacketScan/MLPPP Analyzer, VBA with GL’s GSM, CDMA, and 3G Call Capture Products, and VBA with GL’s 2-Wire Voice/Data Capture Products.”
