GL Communications (News - Alert) Inc., a supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks, has recently revealed an improved version of its Fax Demodulator and Decoder software.

The application is available as FaxDD (VBA038) and FaxDDT38 (PKV104). Furthermore, the VBA038 has two versions – one is a stand-alone command-line fax analysis application, and the other is integrated as a module within GL's Voice Band Analyzer application. The PKV104 is a stand-alone command-line fax analysis application for packet captures.

The new FaxDD application is ideal for processing captured files, and will produce fax TIFF-F images and other transmission information.

Mr. Robert Bichefsky Senior Manager for product development of the company said, “FaxDD is a fax decoder/demodulator application that processes 2-Wire or 4-Wire captures and analyzes voiceband traffic files for fax traffic. Call-center quality systems, brokerages, government agencies, and other entities have a need to monitor fax transactions between two parties. In some cases, the monitoring is done by recording the PCM stream for later conversion to a viewable format. The output of this application includes fields for fax success/failure, data rate, resolution, compression (Modified-Huffman, Modified-Read, Modified-Modified-Read), page size, error-red lines, total lines, total bytes, total pages, image name, and log file name.”

The innovative FaxDDT38 software is designed in such a way that it can easily convert PCAP files and packet capture outputs, from applications such as PacketScan or Wireshark, into TIFF-F files containing the fax image. In addition, this software also offers analysis of T.38 packets, T.30 frames, and general call-flow indicators, serving as a useful T.38 debug tool for system development.

Other features include analysis of files captured by popular IP capturing tools, transmission result reporting, modem rate reporting, single- and multi-page ECM and non-ECM fax sessions,  stand-alone operation from a Batch file or Windows Command screen or as part of the GL VoiceBand Analysis, and decoding of transmission-only captures.

These tools are intended to aid companies with conformance testing, automated stress/load testing, performance testing, remote accessibility, centralized web-based control and analysis, fault testing and analysis, and customized testing.
