GL Announces PacketScan™ with Video QoS

GL Communications Inc. announced today the release of its new PacketScan™ software with Video QoS feature. Addressing the news conference, Mr. Vijay Kulkarni, CEO of the company said, "PacketScan™ is a powerful software tool that features real-time capture and monitoring of IP, VoIP, and now IP based Video traffic:

•segregates, captures, and collects statistics on VoIP calls (H.323, SIP, MGCP, Megaco, T.38, and others), •monitors QOS (quality of service) on voice and video calls, •permits analysis of adherence to protocol standards for the system under test or observation, •provides graphical presentation of analysis, including ladder diagrams of protocols

He added, "We continue to improve PacketScan™ with features that our customers request, and as a result the application has been now enhanced to send H.323 CDR to central Database. This permits monitoring network performance through web based clients such as PacketScanWeb™. Also the application can now calculate Video Statistics such as Media Delivery Index for video sessions. The Media Delivery Index (MDI) is a set of measures that can be used to monitor both the quality of a delivered video stream and to show system margin for IPTV systems by giving an accurate measurement of jitter and delay at network level (Internet Protocol, IP), which are the real causes for quality loss. The Media Delivery Index is typically shown as two numbers separated by a colon the Delay Factor (DF) and the Media Loss Rate (MLR)".

Mr.Kulkarni further added, "New PacketScan™ with Video QoS capability addresses customers long felt need of Video Call Quality checking in VoIP networks".

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 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.

The broadest range of simulation

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 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 intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
