Fax Emulation Using VQuad™
Overview
GL's VQuad™ software can send and receive up to 12 independent and simultaneous T.30 single or multiple page faxes using the Dual UTA HD hardware platform. The user can configure the transmit and receive fax rate from 2,400 bps to 33,600 bps with V.34 supported. Interfaces supported for fax generation include 2-wire FXO and 4-wire analog.
The VQuad™ software includes an easy-to-use Graphical User Interface for sending and receiving Fax calls. Furthermore, the VQuad™ software provides scripting capability for test automation. The VQuad™ software can be controlled remotely for added flexibility. VQuad™ Fax provides all pertinent real-time fax messaging with proper time sequences. One can follow the fax session from start to finish on both the send and receive sides.
VQuad™ also provides a summary for each fax (completed or failed along with results). VQuad™ provides all errors associated with each fax with proper time sequence and an understanding of what the error indicates. All results (errors and summary) can be sent automatically to a web-based dashboard, WebViewer™.
VQuad™ can 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 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.

VQuad™ Fax Events
VQuad™ Fax Emulation includes three event screens, Fax Messages, Fax Summary and Fax Errors. The Fax Messages is shown in chronological order for simple understanding of the fax process. Multiple Fax Message screens can be displayed simultaneously thus showing full duplex fax sessions.
The Fax Summary includes one event per fax (Fax Send and Fax Receive) which shows initial settings and final settings upon fax completion (i.e. Fax Speed, Line Sent, Bad Lines, Pages Received). The Fax Summary also provides insight whether the Fax was successful or the Fax failed in which case an Error will be generated.
The Fax Error screen provides all Fax Errors associated with the Fax Send/Receive. Additional information is provided for each Fax error in order to understand the cause of the error. All event screens can be saved to text file in real-time.
The Fax status as shown on the Fax Event screen displays Total Successful and Total Failed faxes for each VQuad™ device ID.

The other configuration settings include:
- ECM (Error Correction mode) on / off option to automatically detect and correct errors
- RX Image Coding (receive fax only) options - MH (Modified Huffman), MR (Modified read), MMR (Modified Modified READ)
- Auto saved fax (both east and west) to PCM file can be analyzed using GL Insight and GL Fax Extractor

Remote Client WebViewer™
The VQuad™ Fax emulation summary and error results can be sent to the WebViewer™ Central database. These events can be queried using the WebViewer™ web based browser. From the WebViewer™, one can filter the results based on specific Error, Starting or Ending speed, Completed pages, Tx/Rx Lines including Bad Lines, Resolution and ECM settings.
