The FAX CLASS 2 application can ignore low-level T.30 protocol settings. The T.30 protocol stack that runs on the RISC CPU of the Dialogic® Diva® Media Board is able to perform the required adjustment of transmission parameters to provide reliable and fast document transmission without requiring application intervention.
You can overrule the automatic T.30 protocol parameter adjustment with FAX CLASS 2 commands. If your application does not support the appropriate command set or the required features are not part of the FAX CLASS 2 command set, you can use Global fax configuration options or Global Dialogic® Diva® TTY configuration options to overrule the automatic parameter adjustment.
