GENERAL
The V.3400 can send and receive fax documents at speeds up to 14400
bps when used with the appropriate software. As a fax modem, the
modem conforms to EIA-578 which defines a standard interface
between the DTE (a PC with fax software) and the DCE as a fax
modem.
When used with a Class 1 fax software package, V.3400 is CCITT
Group 3 compatible and can send and receive documents at 2400, 4800,
7200, 9600, 12000, or 14400 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 V.3400 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. Those chapters should
be read before this chapter.
Users should understand 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 also the next section of this chapter provides important infor-
mation for proper fax communications.

The NO CARRIER result code indicates that a connection could not be established (no carrier detected) within the number of seconds specified in status register S7, or the dial command has been aborted due to a character sent from the DTE. V.3400... - Page 5 CED is completed, the call is released and the modem will send the NO CARRIER result code. On Hook H In fax mode, the H command instructs the modem to stop any transmis- sion and terminate the call by going on hook. V.3400...
