Previous IETF efforts developed specifications for simple and extended Internet mail-based facsimile service profiles, tailored to interwork with the world of T.30 facsimile. This extension effort will take care of differential routing between classic Internet mail and timely deliveries, and consider with particular regard universal messaging issues and its relation with Internet mail. The WG will produce a final increment of specification for supporting a "full" equivalence of T.30 service over Internet mail. Technical work for this effort includes timely delivery, [image] feature selection/negotiation, document privacy, and integrated specification of Full-mode Facsimile Profile of Internet Mail (FFPIM). For interconnecting fax services over the dial-up telephone network and carriage of facsimile message data over the Internet, two types of interface systems are required: o Internet/Dial-up Fax gateway, moving data from the Internet to classic or Internet-aware dial-up fax products and services o Dial-up/Internet Fax gateway, moving data from classic or Internet-aware dial-up fax products and services to the Internet The working group will also consider the requirements for gatewaying Internet Mail (as profiled for facsimile Simple, Extended modes and FFPIM) with T.30 Facsimile. The working group will specifically take note of quality of service issues and might decide to produce an Implementer's Guide. T.30 facsimile carries expectations of message privacy, so that FFPIM must specify a basic facility via the Internet. Although T.30 does not provide document integrity, users frequently believe that it does. Consequently the Faxext working group will also seek specification of a basic authentication facility over the Internet. T.30 facsimile provides for receiver capability identification to the sender, allowing a sender to provide the "best" fax image the receiver can handle. The Faxext working group will consider mechanisms to provide similar functionality for fax images transferred by e-mail. Additional areas of discussion will be: Annotated fax messages and universal messaging issues as they relate to FFPIM, as well as schema and TIFF extensions required to support the new JBIG-2 (T.88) compression method. The working group will continue the excellent pattern of coordinating activities with other facsimile-related standards bodies, in particular the ITU, VPIM and other WGs, and with using work from related IETF efforts.
