Minimal FAX address format in Internet Mail
Alternative Format: Original Text Document
RFC 3192 Minimal FAX address format in Internet Mail October 2001
These IANA forms used to register the standard elements defined here
are given in the "IANA Considerations" chapter (section 7 of this
document).
All implementations supporting FAX over e-mail address format MUST
support this minimal specification.
1.1 Terminology and Syntax conventions
In this document the formal definitions are described using ABNF
syntax, as defined into [7]. We will also use some of the "CORE
DEFINITIONS" defined in "APPENDIX A - CORE" of that document. The
exact meaning of the capitalized words
"MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
"SHOULD NOT", "RECOMMENDED", "MAY", "OPTIONAL"
is defined in reference [6].
In this document the following new terms are also defined:
I-fax device:
an I-pstn device type [13] which is able to communicate either
directly or indirectly with the traditional FAX over GSTN
service;
mta-I-fax:
the Internet domain name which identifies uniquely an I-fax
device over the Internet (see also mta-I-pstn in [13]);
fax-email:
the complete Internet e-mail address structure which is used to
transport a FAX address over the Internet e-mail service (see
also pstn-email in [13]).
2. Minimal Fax address
The minimal fax address within e-mail has been defined for
consistency with reference [13] and it contains two elements: the
fax-mbox and an optional qualif-type1 element.
More precisely the GSTN minimal address specification requires the
use of a unique service-selector for each specific application
(section 2 in [13]).
The "service-selector" defined for the fax service is as follows:
service-selector = "FAX"
