VQuad™ coupled with Dual UTA HD provides easy and flexible “quality of service” assessment across almost every network interface – whether its IP, TDM, Analog, or Wireless – one platform handles all possibilities - Voice, Data, Video Quality, and now Fax Quality. Fax is not going away – not by a long shot. For financial and legal reasons fax is a necessity.

GL’s VQuad™ has been enhanced to support sending and receiving of up to 4 independent and simultaneous T.30 faxes over the Dual UTA HD hardware platform. The user can configure the TX and RX fax rate from 2400 bps to 33,600 bps with V.34 fully supported. Interfaces supported for fax generation include 2-wire FXO and 4-wire analog. Support for additional interfaces such as T1/E1 and VoIP (T.38) is coming soon.

In addition to the fax messages, VQuad™ Fax also provides fax summary for each fax (fax completed or failed along with fax results). VQuad™ 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™ Central Database for query using the WebViewer™ browser.

In order to fully support GL Fax Analysis products, VQuad™ 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™ or GL 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™ provides access and display, in real time, to all results associated with VQuad™ including the Fax events, errors, and summary logs.

Main Features:

  • Fax Emulation supporting up to 4 independent and simultaneous sessions with speeds up to 33600 bps (V.34).Supports both Tx and Rx fax emulation using VQuad™ with Dual UTA HD analog interfaces (2-wire FXO, 4-wire balanced, 4-wire Handset, PTT).
  • VQuad™ Fax events include messages, summary, and errors log
  • Ability to auto save fax (both East and West directions) to PCM file for enhanced analysis using GL Insight™ and GL Fax Demodulator/Decoder
  • VQuad™ scripting supports both fax send and receive session configuration
  • Support for querying Fax events/results/errors over web interface.
  • Support for additional interfaces such as T1/E1 and VoIP (T.38) is coming soon
Fax emulation is fully automated using VQuad™ scripts and can be initiated remotely such that one VQuad can control both sides of the fax. VQuad™ 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.
