Since the ipp group may not be aware of the content of the charter of the
ietf-fax group, I am submitting it to this list. I have some comments that
I will submit separately.

DESCRIPTION OF WORKING GROUP:
Facsimile (fax) serves as a reliable, inexpensive global
communications service. As the Internet becomes pervasive,
integrating fax and Internet services is appealing in terms of cost-
savings and opportunities for functional enhancements. This working
group will pursue an initial round of review and specification for
enabling standardized fax over the Internet. In the interest of
making progress quickly, an email-based service will be the first
transport mechanism pursued, since it requires the least additional
technical effort.
Facsimile/Internet integration can be considered in terms of
three user service models, in order of increasing technical
difficulty:
=85 Messaging, e.g., email & high latency
=85 Session-based, for observed delivery, with or=
without
capabilities negotiation
=85 Real-time, for telephone replacement and transparent to existing
fax machines
For interconnecting fax services over the dialup telephone
network and carriage of fax data over the Internet, two types of
translations devices are required:
=85 Internet/Dialup Fax gateway, moving data from the Internet
to classic
or Internet-aware dialup fax services
=85 Dialup/Internet Fax gateway, moving data from classic or Internet-
aware dialup fax services to the Internet
This working group shall include consideration of requirements for
these gateways, but will defer specifying their details.
The Fax working group will focus on an initial set of activities
to create a core fax-related service over the Internet, using existing
protocols and specifications where possible. Its activities will
include development of standardized terminology, standardized data
representation, and standardized data transport methods, attending to
addressing and reliability concerns. Common terminology will ensure a
shared framework for participants from the Internet and the facsimile
worlds. The second task will review existing facsimile-related
Internet data specifications and accept, modify, replace or augment
them, with particular attention to their encapsulation, such as via
MIME. The third task will provide for carriage of facsimile data via
Internet mail The fourth task will detail the operational constraints
for achieving session-oriented use of messaging, tailored for timely
delivery with the sender waiting for delivery confirmation.
The dominant use of fax today is during a real-time connection
over the dialup telephone network; hence an Internet-based direct
replacement service would save significant long-distance telephone
charges. However it is believed that this service is the most
difficult task to produce over the Internet, technically, whereas an
email-based service is likely to be the simplest.
The working group shall coordinate its activities with other
facsimile-related standards bodies.
GOALS AND MILESTONES:
Feb, 97 Submit terminology document and new or modified data
specifications onto standards track
Mar, 97 Submit email specification onto standards track
Jul, 97 Submit interactive-time fax-over-Internet specification onto
standards track
