Abstract

   This document defines a number of terms useful for the discussion of
   Internet Fax. In addition, it describes the goals of the Internet Fax
   working group and establishes a baseline of desired functionality
   against which protocols for Internet Fax can be judged. It
   encompasses the goals for all modes of facsimile delivery, including
   'real-time', 'session', and 'store and forward'.  Different levels of
   desirability are indicated throughout the document.

1. Introduction

   Facsimile (Fax) has a long tradition as a telephony application for
   sending a document from one terminal device to another.

   Many mechanisms for sending fax documents over the Internet have been
   demonstrated and deployed and are currently in use. The general
   application of using the Internet for facsimile is called "Internet
   Fax".

   This document defines a number of terms useful for the discussion of
   Internet Fax. In addition, it describes the goals for Internet Fax and
   establishes a baseline of desired functionality against which
   protocols for Internet Fax can be judged. It encompasses the goals for
   all modes of facsimile delivery, including "real-time", "session", and
   "store and forward" (terms defined in Section 2 of this document).

   1.1 Terminology used within this document

   Within this document, different levels of desirability for a protocol
   for Internet Fax are indicated by different priorities, indicated in
   {braces}:

      {1} there is general agreement that this is a critical
          characteristic of any definition of Internet Fax.
      {2} most believe that this is an important characteristic
          of Internet Fax.
      {3} there is general belief that this is a useful feature
          of Internet Fax, but that other factors might override;
          a definition that does not provide this element is
