Network Analysis Software monitors Ethernet/IP/VoIP traffic.

Press Release Summary:

With PacketScan(TM), users can monitor IPv4 and IPv6 networks; segregate, capture, and collect statistics on VoIP calls; and monitor QoS on voice/video calls. Program delivers graphical presentations of analysis, including ladder diagrams of protocols. In addition to providing detail decodes of FAX calls, PacketScan(TM) can extract Fax images from captured fax calls. Software can capture and analyze calls for theoretically infinite time, limited only by finite space of hard disk or network hard drive.

Original Press Release:

GL Announces Enhanced PacketScan(TM) Software

Gaithersburg, Maryland, USA - GL Communications Inc. announced today the release of enhanced PacketScan(TM) software, an Ethernet/IP/VoIP Traffic Analyzer.

Speaking to reporters, Mr. Karthik Ramalingam Manager Product Development of the company said, "PacketScan(TM) is a powerful software tool that features real-time capture of Ethernet, IP, VoIP, and IP based Video traffic with extensive analysis using graphs, and statistics. Some of the important applications of PacketScan(TM) are:

o Monitors live IPv4 and IPv6 networks,

o Segregates, captures, and collects statistics on VoIP calls (H.323, SIP, MGCP, Megaco, T.38, and many others),

o Monitors QOS (quality of service) on voice and video calls,

o Permits analysis of, and conformance to protocol standards for the system under test or observation,

o Provides graphical presentation of analysis, including ladder diagrams of protocols

And PacketScan(TM) can monitor, report, analyze, and capture calls for theoretically infinite time, limited only by the finite space of your hard disk or network hard drive."

He added, "Users can listen/record audio and video data of a session in real-time; perform power, frequency, spectral, tone and digit analysis, and video analysis with ease and precision; get an exact picture of QoS (quality of the service)."

Mr. Ramalingam further added, "PacketScan(TM) can work with PacketScanWEB(TM) a central monitoring system for a comprehensive view of network performance. It features rich graphics, ladder diagrams, CDRs (Call Data Records), and compatibility with almost every voice CODEC."

Important Enhancements Introduced to PacketScan(TM) Software:

o IPv6 Support

The application is now enhanced to capture and analyze calls over IP version 6 (IPv6) Protocol.

o Extract Fax Image from Fax Call

In addition to providing detail decodes of a FAX call, PacketScan(TM) now includes an option to extract Fax images (in TIFF format) from captured fax calls. The analyzer can also be set to trigger on fax calls and store the extracted fax images in a folder automatically during the capture.

o Additional Codec Support

Supports two more codecs GSM-HR (Half Rate) and GSM-EFR (Enhanced Full Rate). Also supports MOS Scores for AMR_WB codec (for all 9 modes).

o Report Mid Call Digits

Mid call outband digits detected on a call are now reported along with SIP signaling events in CSV reports.

o Import Wireshark Traces

Provides an option to Import Wireshark traces (.pcap and .cap) into the Analyzer. Wireshark traces can be converted to .HDL (GL's trace format) file and opened in the analyzer for analysis.

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) are all 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.
