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.

Fax Tx/Rx Configuration

VQuad™ scripting provides the ability to send and receive a fax session along with specifying necessary fax configuration settings.

The settings include Max Transmit Rate and Min Receive Rate which can effectively restrict available fax sessions.

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
