Fax configuration options
Option Description
Fax speed limit Allows to limit the transmission speed. Normally, you do not need to limit the fax
speed because the Diva Media Board automatically negotiates the appropriate
speed.
Disable fine resolution Disables the transmission of fax messages with high resolution.
Disable Error Correction
Mode (ECM)
Disables the transmission of fax messages using ECM (Error Correction Mode).
Use ECM frame length of
64 bytes
Forces usage of HDLC frames with a maximum length of 64 bytes if transmitting fax
messages using ECM (Error Correction Mode).
Disable 2D fax document
compression
Disables usage of 2D fax document compression. This option also disables the
automatic (transparent to application) fax document compression provided by the
Diva Media Board in order to increase the effective transfer speed of fax messages.
Disable T.6 fax document
compression
Disables usage of T.6 fax document compression. This option also disables the
automatic (transparent to application) fax document compression provided by the
Diva Media Board in order to increase the effective transfer speed of fax messages.
Disable uncompressed T.6
fax document lines
In some cases, compression of a fax document line results in a line that is longer
than the uncompressed original. The T.6 protocol allows you to reduce the fax
transmission time by transmitting such lines without compression. This option
disables the line compression optimization.
Refuse incoming polling
requests
Disables incoming polling requests.
Hide "total pages"
information in fax
message
Hides the "total pages" information field in the fax message.
Hide "head line"
information in fax
message
Hides the "headline" information field in the fax messages.
Hide "page info"
information in fax
message
Hides the "page info" (i.e. message head) field in the fax messages.
Disable fallback to lower
speed on failure
"Feature fallback" is used to prevent excessive resending of fax documents if
working over poor quality lines. The Diva Media Board internally saves the fax ID of
the last peer and the results of the fax transmission from this peer. If the results of
the last fax transmission were negative and the application starts message re-
transmission, the Diva Media Board will detect this and fallback to a lower transfer
speed. This setting allows for disabling fallback.
