GL Announces Enhanced Fax Emulation
Gaithersburg, Maryland, USA - GL Communications Inc. announced today the release of its latest Enhanced Fax Emulation software.
Speaking to reporters, Mr. Robert Bichefsky Senior Manager said, "Fax emulation has never been easier using GL's products. Now - low cost, easy to use fax emulation is available with our VQuad(TM) and Dual UTA 2-wire and 4-wire hardware platforms.
VQuad(TM) coupled with Dual UTA provides easy and flexible "quality of service" assessment across almost every network interface - whether it's IP, TDM, Analog, or Wireless - one platform handles all possibilities - Voice Quality, Data Quality, and now Fax Quality. Fax is not going away - not by a long shot. For financial and legal reasons fax is a necessity."
He added, "GL's VQuad(TM) has been enhanced to support sending and receiving of up to 4 independent and simultaneous T.30 faxes over the Dual UTA hardware platform. The user can configure the TX and RX fax rate from 2400 bps to 33,600 bps - V.34 is fully supported. Interfaces supported for fax generation include 2-wire FXO and 4-wire analog. Fax Emulation is fully automated using VQuad(TM) scripts and can be initiated remotely such that one VQuad can control both sides of the fax. VQuad(TM) Fax provides all pertinent real-time fax messaging with proper time sequences. In other words, one can follow the fax session from start to finish on both the send and receive sides."
Mr. Bichefsky further added, "In addition to the fax messages, VQuad(TM) Fax also provides fax summary for each fax (fax completed or failed along with fax results). VQuad(TM) Fax provides all errors associated with each fax with proper time sequence and an understanding of what the error might indicate. All results (errors and summary) can be sent automatically to the WebViewer(TM) Central Database for query using the WebViewer(TM) browser.
In order to fully support GL's Fax Analysis products, VQuad(TM) Fax provides the ability to automatically save the fax session (both East and West directions) to a PCM file. This file can be exported to GLInsight(TM) or GL's Fax Demodulator/Decoder analysis software packages for further analysis of the fax session. GL's Fax Demodulator / Decoder can be configured for fully automated analysis.
GL's WebViewer(TM) provides access and display, in real time, to all results associated with VQuad(TM) including the Fax events, errors, and summary logs."
o Fax Emulation supporting up to 4 independent and simultaneous sessions with speeds up to 33600 baud (V.34). Supports both Tx and Rx fax emulation using VQuad(TM) with Dual UTA analog interfaces (2-wire FXO, 4-wire balanced, 4-wire Handset, PTT).
o VQuad(TM) Fax events includes messages, summary, and errors log
o Ability to auto save fax (both East and West directions) to PCM file for enhanced analysis using GL Insight(TM) and GL Fax Demodulator/Decoder
o VQuad(TM) scripting supports both fax send and receive session configuration
o Support for querying Fax events/results/errors over web interface
o Support for additional interfaces such as T1/E1 and VoIP (T.38) is coming soon

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.
