In a word, no. Unless your data modem has specific additional support for fax, you cannot communicate with fax devices using a data (only) modem. Simply put, the problem is that the modulation methods (tones) used to communicate data are different from those used to communicate faxes. Typically the modulation schemes used for fax are synchronous half-duplex while those used for data (at least by most UNIX and PC people) are asynchronous and full-duplex. Also, data modems, once they have negotiated a modulation scheme, tend to continue with the same one through out the session. Fax modems switch before and after each page between a high-speed modulation scheme used to transmit the image data and a lower (300 or 2400 bps) scheme to exchange control information. The following table outlines this briefly (see also part 1 of this FAQ for definitions of V.*). Data Rate Data Modulation Std. Fax Modulation Std. ========================+==========================+======================== 9,600 bps | V.32 | V.29 ------------------------+--------------------------+------------------------ 14,400 bps | V.32bis | V.17 ========================+==========================+======================== _________________________________________________________________ Q.1A CAN MY FAX MODEM TRANSMIT DATA? In a word, maybe. There is a standard proposed by the EIA/TIA/ANSI called Binary File Transfer (BFT) that extends the fax Group III modulation and protocols for bulk data transfer. The problem, of course, is that few fax modems or software packages provide support for this mechanism. Q.2 How can I fax PostScript or PCL documents using computer-based fax? In addition to the basic software to drive your fax modem/board, you will need specific software that can convert PostScript or PCL files into a raster image format compatible with your fax software package. GhostScript, for example, is a publically available software package that can convert PostScript into raster image format (although there are varying opinions on the quality of the font support). In the commercial world, most of the vendors of fax software provide software that can handle PostScript and/or PCL. When purchasing such software (a) check how many different fonts are supported (it's a pain to be able to use, say, NewCentury on your laser printer only to find it is not included in your fax package), and (b) in the case of PCL, check which level of the language is supported (PCL-4 does not support scalable fonts, PCL-5 does). _________________________________________________________________ Q.3 How can I view incoming faxes on my computer? In the PD world, there are a number of image-viewing packages available for X (such as xv). In the commercial world, most fax vendors provide support for the commonly available devices (in the case of UNIX, X; in the case of PC-UNIX, VGA and HGA support. Some vendors support other graphics-capable terminals such as the Wyse WY-160.) _________________________________________________________________ Q.4 How can I print incoming faxes on my computer? Most fax software packages include software to convert fax images into print data streams compatible with dot matrix, HP PCL, or PostScript printers. Also the publically available (where?) pbmplus filter kit will handle most image formats. _________________________________________________________________ Q.5 Can fax modems also handle data or voice calls? Not all fax boards can handle data (some are fax only). Most (all?) external fax modems can handle data as well as fax. Some (but not all) fax modems and software can automatically distinguish between data and fax calls and answer them appropriately. Some DOS/WINDOWS based products can automatically distinguish between voice and fax/data calls and operate as a digital answer machine as well as a fax machine. Also, several companies sell devices which can switch incoming calls between a fax machine, a telephone answering machine, and a modem. [Suggestions anyone?] _________________________________________________________________ Q.6 What resolution are fax images? The standard resolution for faxes is 3.85 scan lines/mm (approx. 98 dpi vertically) with 1728 pixels across a standard scan line of 215 mm (approx. 204 dpi horizontally). The optional "fine" resolution is 7.7 scan lines/mm (approx. 196 dpi vertically) with the same horizontal resolution. Many Group III fax machines use non-standard frames to negotiate higher resolutions (typically 300x300 dpi and 400x400 dpi) with other fax machines by the same manufacturer. Two fax machines (or modems) must negotiate a common resolution, page width, and page length before sending each page. The standard requires that all Group III fax machines suppport at least standard resolution and A4 size so that common ground can always be found. Extensions to the Group III standard to support these higher resolutions in a standard way have been proposed. Their current status is not known [Need more information]. [Need more information on resolutions supported by Group IV]. _________________________________________________________________ Q.7 Can I take a fax file and edit it? When faxes exchange information, it is done in the form of compressed images (with the exception of BFT). If you wish to edit or otherwise manipulate a received fax file you have two options: 1. edit the file using a "paint" program that will accept the fax file (unfortunately there is a wide range of file formats for image files and you may have to work to find a format that is common between your fax application and your paint program). 2. pass the file through an OCR program that will attempt to convert the image into ASCII (or word processing file format). The problem here is that most OCR programs are tuned to work with 300x300dpi images and faxes are either 98x204 or 196x204. _________________________________________________________________ Q.8 Is there a standard program interface (API) for fax communications? There are many API's that are used for fax communications. Words marked by -word- are further explained in the glossary in Part 1 of this FAQ. At the hardware level, the two standards that govern the exchange of commands between a host computer and a fax modem are EIA-578 (-Class 1-) and EIA-592 (-Class 2-). At the software level there is one "official" standard and a number of "industry standards". The one "official" standard is ITU-T T.611 ([need more information on this standard]). The most widely known industry standards are -CAS- (Communicating Applications Standard (?)) invented by Intel and DCA and tied closely to the Intel architecture, and -FaxBios- (developed by an industry consortium) which is less machine-dependent (implementations for MS-DOS and WINDOWS have been published and sporadic work on UNIX and other bindings is underway). _________________________________________________________________ Q.9 How can I share my single phone line with voice, fax, data, etc. There are a number of devices on the market (suggestions from happy campers welcome) that will try to distinguish between an incoming voice, fax, or data call and route the call appropriately. These fax switches attach to the phone line and then the other devices (your normal voice phone/answering machine, fax machine, data modem, etc.) are attached to the fax switch). All devices work on one of two general principles: listening for CNG or voice, or listening for distinctive ring patterns (cadences). In the first case the device will answer the phone and try to guess what it should do based on what it hears. Some machines play back a sound of a phone ringing so that humans dialling in think the phone is still ringing when in fact the fax switch is listening to see if the call is from a fax machine or a human. If the CNG tone (see Part 1 for a definition of CNG) from the calling fax machine is heard, then the switch connects the call to the fax machine, otherwise the call is deemed to be a voice call and is connected to your phone/answering machine. A slightly more sophisticated approach is for the fax switch to answer the phone and play a short recorded announcement. If, during the announcement the CNG tone is heard, then the call is switched to the fax machine. If no CNG tone is heard but sound is heard after the announcement, then the call is assumed to be voice and switched appropriately. If nothing is heard then the switch either considers the call a data call and switches it to a modem or considers it a fax call from a machine that does not generate a CNG and switches it to the fax machine. The other approach relies upon an optional service available from some telcos called "SmartRing", "Distinctive Ring", "RingMaster", "Ident-a-Ring", etc. This feature allows one to have more than one phone number associated with the same phone line. Incoming calls using the different phone numbers can be differentiated by the different ringing patterns (i.e. one long ring, two short rings, three short rings, etc.) The fax switch distributes the call based on the ring cadence it detects. The advantage of the first approach is that one does not have to send more money to the phone company (or depend upon the availability of the "SmartRing" feature being available). The disadvantage is that it is not always reliable (especially in the face of fax machines that do not generate CNG tones). The advantage of the second approach is that it is very very reliable. The disadvantage is that it requires the availability of the "SmartRing" feature from one's telco as well as sending more money to the telco every month. _________________________________________________________________ Q.10 How can I send a fax over the Internet?

The TCPA imposes restrictions on the use of automatic telephone dialing systems ("autodialers"), artificial or prerecorded voice messages, and telephone facsimile machines to send unsolicited advertisements. The TCPA also directs the FCC to adopt regulations to protect residential telephone subscribers' privacy rights to avoid receiving telephone solicitations to which they object. The FCC adopted rules and regulations, effective December 20, 1992, implementing the TCPA. The FCC will be monitoring complaints about automated calls and unwanted telephone solicitations to determine whether additional action to limit or to prohibit such calls would be appropriate. DO FCC RULES BAN UNSOLICITED ADVERTISEMENTS TO TELEPHONE FACSIMILE MACHINES? Yes. Effective December 20, 1992, FCC rules ban the transmission of unsolicited advertisements to telephone facsimile machines. An "unsolicited advertisement" is defined as a transmission advertising the commercial availability or quality of property, goods or services without the prior express invitation or permission of the person or entity receiving the transmission. Unsolicited advertisements may not be transmitted by any device to a telephone facsimile machine unless the person receiving the facsimile has given prior express invitation or permission to receive it. If the sender and the recipient have an established business relationship, an invitation or permission to receive unsolicited facsimile advertisements is presumed to exist. However, the recipient may end an established business relationship by requesting that no further unsolicited advertisements be sent, thus revoking any invitation or permission to receive further transmissions. WHAT OTHER REQUIREMENTS APPLY TO THE USE OR MANUFACTURE OF TELEPHONE FACSIMILE MACHINES? FCC rules require that each transmission to a telephone facsimile machine must clearly contain, in a margin at the top or bottom of each transmitted page or on the first page of the transmission, (1) the date and time the transmission is sent (2) the identity of the sender and (3) the telephone number of the sender or of the sending machine. All telephone facsimile machines manufactured on or after December 20, 1992 must have the capacity to clearly mark such identifying information on the first page or on each page of the transmission. [Note, according to the FCC January 13, 1993 Public Notice, the requirement to mark faxes with the above identifying information on applied to fax machines and not for fax cards used in computers pending reconsideration proceedings.] WHO IS RESPONSIBLE FOR COMPLIANCE WITH FCC RULES ON TELEPHONE FACSIMILE TRANSMISSIONS? The person on whose behalf a facsimile transmission is sent will ultimately be held liable for violations of the TCPA or FCC rules. DO THE TCPA AND THE FCC'S RULES PREEMPT STATE LAW? The TCPA specifically preempts state law where it conflicts with the technical and procedural requirements for identification of senders of telephone facsimile messages or automated artificial or prerecorded voice messages. The TCPA and the FCC's rules do not preempt state law which imposes more restrictive requirements or regulations for (1) the use of facsimile machines or other electronic devices to send unsolicited advertisements, (2) the use of autodialers, (3) the use of artificial or prerecorded voice messages, or (4) the making of telephone solicitations. Thus, depending on state law, the TCPA, the FCC's rules and/or state laws could apply to your company's services. You should contact the state public utilities commission in each state where your company provides the services listed in the previous paragraph to determine what laws apply in those states. WHERE CAN I ORDER A COMPLETE COPY OF THE TCPA AND THE FCC'S ORDER EXPLAINING IMPLEMENTATION OF THAT ACT? Copies can be ordered from the FCC's contractor for public records duplication: Downtown Copy Center, 1990 M Street, N.W., Suite 640, Washington, D.C. 20036 (telephone: (202) 452-1422). You should ask for copies of the Telephone Consumer Protection Act and the Report and Order in CC Docket No. 92-90 released by the Commission on October 16, 1992 (In the Matter of Rules and Regulations Implementing the Telephone Consumer Protection Act of 1991). ============================================================================== SOURCES OF INFORMATION I.1 Standards Related to Facsimile Communication CCITT (now renamed ITU-T) The Blue Book, Volume VII - Fascicle VII.3 Recommendation T.0 - T.63 EIA/TIA/ANSI EIA/TIA-602 Data Transmission Systems and Equipment-Serial Asynchronous Automatic Dialing and Control "This is the standard for the basic Hayes command set."

Historically they ran the "Facsimile and Image Communications Conference" every spring and every fall they held the "Annual Computer Fax Conference). In 1995, however, BIS is planning to merge these two conferences into a single "FAXWORLD'95" conference. Current plans are to hold this in San Francisco from June 5-7th, 1995 but rumours abound that it will be pushed back to the first week in December, 1995.
