[comp.dcom.telecom] Faxnet Info Request

HANK@barilvm.bitnet (Hank Nussbacher) (01/12/90)

I am looking for information about Faxnet products and integration to
PCs.  I am aware of Fax machines that can maintain lists of numbers to
dial so that one can have a distribution list via FAX.  But what if I
am on a PC and I want to send my data directly from my PC to a Faxnet
machine so that certain copies will be sent via Fax but some will be
sent via e-mail so that the destination user will receive the letter
in computer readable format.
 
What of the reverse?  Someone feeding in a typed letter into a FAX and
the FAXnet machine sending it to some people via straight FAX and
others via e-mail.  Is that posssible?
 
I am interested in hearing of any papers, documents, articles on this
matter.
 

Many thanks,
Hank

In article <2796@accuvax.nwu.edu> you write:

All of the major E-Mail services such as MCI Mail, AT&T Mail, and
Compuserve do this already.  Fax addresses typically look like email
addresses to a pseudo-system named fax or something like it.  To get
data from your PC to the E-Mail system you can use something like
Lotus Express which uses a proprietary protocol on top of X.PC to talk
to MCI Mail or UUPC, a free PC implementation of uucp, which should be
adequate to talk to AT&T Mail.

Not really.  Current OCR technology, certainly current low-cost OCR
technology, has a high error rate and I doubt anyone would be happy
with an OCR interpretation of a document scanned in via a Fax machine.
What is possible now is to receive faxes on your PC and treat the
image as a graphic email message.  One particularly clever
implementation allows you to attach the fax card to a DID trunk so the
fax card can have a whole lot of phone numbers, one per email user,
and route the incoming graphics messages based on the number called.

Your problem could be at the receiving end of the FAX transmission. If
the receiving FAX is looking for a Calling Tone ( a pulse that
identifies itself to the other FAX) and there isn't one, it could
assume the answer is voice. The opposite is true also. If YOUR machine
wants a Calling Tone and doesn't get it, it could assume that it was a
voice answer.
