GL Communications (News - Alert), a company that specializes in test monitoring and analysis equipment for TDM, wireless, IP and VoIP networks, has enhanced its PacketScan software. The improvements to the Ethernet/IP/VoIP traffic analyzer will enable it to extract images from IP faxes, along with other innovative enhancements.

According to company officials, the new version of the software will feature real-time capture of Ethernet, IP, VoIP and video traffic, providing extensive analysis using graphs and statistics. The solution will be able to monitor both IPv4 and IPv6 networks, and segregate, capture and collect statistics on a range of VoIP calls. It will also monitor quality of service on voice and video calls, analyze conformance with protocol standards and present the analysis in a graphical format.

"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)," said Karthik Ramalingam, manager of product development at GL Communications.

One important use of the PacketScan software is in IP fax applications. First, it will provide detail decodes of fax calls. It also includes an option to extract images from captured fax calls and can be set to trigger on fax calls and store the extracted fax images in a folder.

In addition to fax applications, the PacketScan solution has other key features. It supports additional codecs: GSM-HR (half rate) and GSM-EFR (enhanced full rate) and also supports MOS Scores for AMR-WB codec for all nine modes. PacketScan will capture and analyze calls over IPv6 and report mid-call outband digits and SIP signaling events in CSV reports. Additionally, the software provides an option to import Wireshark traces (both .pcap and .cap) into the analyzer. These traces can then be converted to GL’s trace format (.HDL) for analysis.
