Black Box 3600 MODEM manual Chapter Fax Operation

Chapter 9

Fax Operation

The Modem 3600 can send and receive fax documents at speeds up to 14,400 bps, with the appropriate software. As a fax modem, the modem conforms to EIA-578, which defines a standard interface between a PC with fax software and the DCE as a fax modem.

When used with a Class 1 fax software package, Modem 3600 is CCITT Group 3 compatible and can send and receive documents at 2400, 4800, 7200, 9600, 12,000, or 14,400 bps with any Group 3 fax machine or PC with a fax modem.

Service Class selection configures the modem for Class 0 data mode or Class 1 fax mode. The LCD display indicates when fax mode is enabled. The Modem 3600 default configuration is for data mode; Service Class is normally only changed by the software as necessary.

Previous chapters in this manual contain information about the modem that should be understood prior to fax operation.

Read the fax software manual before attempting fax communications.

Fax Operation

The user's manual for the Class 1 fax software package should provide most information necessary to configure the software and send and receive faxes.

The information in Chapter 2 of this manual should be considered as well, and the “Modem Initialization” section on page9-2 provides important information for proper fax communications.
