Fax Demodulator/ Decoder

“FaxDD™ is a fax decoder/demodulator application that processes 2-Wire or 4-Wire captures and analyzes voiceband traffic files for fax traffic. FaxDDT38™ also provides analysis of the T.38 packets, T.30 frames, and general call-flow indicators.

Gaithersburg, Maryland (PRWEB) April 23, 2013

GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, announced today its enhanced Fax Demodulator and Decoder software.

Speaking to media persons, Mr. Robert Bichefsky Senior Manager for product development of the company said, “Fax decoder/demodulator (FaxDD™) application is used for processing captured files and produce the Fax TIF image and other transmission information. The application is available as FaxDD™ (VBA038) and FaxDDT38™ (PKV104).

FaxDD™ has two versions – one, as a stand-alone command-line fax analysis application and other, integrated as a module within GL's Voice Band Analyzer application. FaxDDT38™ is a stand-alone command-line fax analysis application for packet captures.”

He added, “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.”

Mr.Bichefsky further added, “GL’s FaxDDT38™ software converts PCAP files and outputs of packet capture applications such as PacketScan™ or Wireshark, into TIFF-F files containing the fax image. FaxDDT38™ also provides analysis of the T.38 packets, T.30 frames, and general call-flow indicators. So it is a valuable T.38 debug and test tool, aiding significantly in system development.”

Main Features:

·2-wire or 4-wire captures, A-Law, µ-Law, 13-bit linear PCM, and16-bit linear PCM data formats
·Operates stand-alone from a Batch file or Windows Command screen or as part of the GL VoiceBand Analysis application to produce decoded fax image TIFF files and call logs
·Output contains page-by-page packet statistics and Fax image summary
·Fax image output in TIFF-F format
·Reports Transmission Result
·NO_FAX: Input is not a fax signal (no V.21 flags detected)
·FAX_NO_PAGES: Input is a fax signal but no pages were recovered
·COMPLETE_SUCCESS: All pages recovered had less than 10% bad lines
·PARTIAL_SUCCESS: At least one page had more than 10% bad lines
·NSS_MODE_ON: Session is using non-standard facilities as opposed to T.30
·Reports Modem Rate, Resolution, Encoding, and Page Size
·2400, 4800, 7200, 9600, 12000, or 14400 bits per second
·HIGH (204x196dpi), LOW (204x98dpi), or SUPER_HIGH (204x391dpi)
·Modified Huffman (MH), Modified READ (MR), or Modified-Modified READ (MMR).
·A4, B4, or A3.
·Supports analysis of files captured by popular IP capturing tools. T.38 version 1 is supported.
·Single- and multi-page ECM and non-ECM fax sessions are supported.
·Decoding of transmitter-only captures is supported for non-ECM faxes.
