The following notes apply to the Dialogic combined voice and fax boards VFX/40 and VFX/40E, and the newer Dialogic JCT boards.

For more information on Dialogic JCT boards visit the Dialogic web pages here.

Hardware Installation

There are no switches to set for fax operation. The board is addressed via the voice board using the unit number set on the thumb-wheel and DIP switch 2-2.

Each fax and voice channel set shares a single telephone connection socket on the mounting bracket of the combined board. Channel 1 is nearest the fixing screw and channel 4 is nearest the board connectors.

Cover Sheets

The FAX40 board driver software does not directly support 'include' files in ASCII files. Instead it allows a page to be built from up to three segments in separate source files. CopiaFacts works around this problem by allowing the include file text "*INC:filename" in cover sheet templates and then building the separate segments for you automatically, with the following restrictions:

There must be a maximum of one ASCII block in the file, so that....

The include for a page header must be the first line in the template.

The include for a page footer must be the last line in the template.

If you have to have text both above and below a graphic image, you can have the ASCII block first, then include the image, then make your second include file an ASCII file. However CopiaFacts variables are not expanded in included ASCII files.

Merged files

You can merge up to three images or ASCII files on a single faxed page. This is controlled with the $merge_page command. When the merge-page feature is enabled, any image processed does not end a fax page, but has the following image appended to it. The maximum number of segments is THREE. For example:

; IIF Number 123

$type decision

$merge_page enable

$add_image part1

$add_image part2

$merge_page disable

$add_image part3

Alternatively:

; IIF Number 123123

$type group_image

$merge_page enable

$image_file 123001

$image_file 123002

$merge_page disable

$image_file 123003

If you accidentally add more than two items with merge_page enabled, or fail to send at least one item with merge_page disabled the fax will either not be sent or will not come out the way you expected. All image files participating in a merge page must have the same vertical resolution (normal or fine), but CopiaFacts does not check that this is the case.

Supported File Types

CopiaFacts supports three fax file formats for these boards: TIFF/F, JTFax, and ASCII. The file type is determined automatically and the file extension is not significant. If a file is not detected as TIFF or JTFax it is assumed to be ASCII. TIFF files with incomplete tag sets will be rejected and the transmission will fail.

The board drivers support sending ASCII pages with or without padding them to full page size. Full pages are specified with the 'full page' option in the COPIAFACTS program. ASCII pages which end with a TIFF image are not padded.

Multiple page files may have .TIF or .1 extension, but if a .1 file is a multiple-page TIFF then the system will not send any .2, .3, .4, etc files which are present. It will also send only the first page from a TIFF with numeric extension greater than 1.

Received files are stored in multiple-page-per-file TIFF format unless the Multi-Page TIFF COPIAFACTS run-time option is used to disable this. All image files will be transmitted using the resolution in which the file is stored. ASCII files such as cover sheets will be transmitted in normal resolution, as will any included graphics files.

The boards support conversion between normal and fine formats. The default is to send all image files using the resolution in which the file is stored, but this can be overridden with the $image_res command. ASCII files such as cover sheets will be transmitted in normal resolution unless the preceding header image file is fine resolution (in which case the footer image file, if present, will also be sent in fine resolution).

Standard wide fax formats are supported (2048 and 2432 pixels).

ASCII file controls

You can embed the following control sequences in an ASCII file:

                 3 lines/inch               <ESC>L2

                 4 lines/inch               <ESC>L1

                 6 lines/inch (default)        <ESC>L0

               8 lines/inch                  <ESC>L4

Tab Stop Setting (default 8)             <ESC>n

Fax Header

Up to 132 characters are available and any CopiaFacts variables may be expanded. In addition you may use %P to place the page number in the header.   See also the Fax Header Lines topic.

Inserting the Remote CSID in a fax header line

Use %R to place the 20-character remote CSID string (if available) in the header line.
