Abstract This draft describes goals of Terminal Mode which was proposed in ITU-T SG16 meeting on November 2000 at Geneva. The Terminal Mode supports the transfer of image data, capabilities exchange and confirmation for Store and Forward internet fax terminals having limited memory and small CPU power. Terminal Mode also supports all features of Group 3 facsimile on the Internet using T.30 signals in capability exchange.

Introduction The specification defines the Terminal Mode carriage of facsimile data over the Internet, and its functionality necessary for achieving reliability, timeliness and capabilities negotiation for Internet mail that is on a par with classic T.30 facsimile. Terminal Mode is intend to implement features of all classic T.30 facsimile over Internet, providing a level of service that approximates the level currently enjoyed by fax users, and providing all fax-specific features that will be implemented in an embedded fax device software working on G3 fax based system with limited memory size and CPU performance. These fax specific features to be supported are Polling, Subaddress, Password, senders ID, Internet Selective Polling address, Internet Routing address and Double Side Printing, which will be easy to develop gateway function between G3 fax and Terminal Mode Internet fax. Also new features are designed such as (1) legal support by fax header or cover page with sender's ID and Time&date, (2) end to end SMTP session and (3) One SMTP session for capability exchange/image transmission/confirmation. 2. Goals for Terminal Mode Those are goals for Terminal Mode. Easy to Implement Interworking with G3 fax, IFAX Simple Mode and EIFAX Features shared with G3 fax Proof of delivery/receipt Capability Exchange Timely Delivery Data Format Support Cover Page and Fax Header Date and Time Information Legal Issue Legal Identity Exchange Quality of output Addressing Support Use of Existing Infrastructure Reliably in the global Internet Security Maeda Internet draft [Page 3] INTERNET-DRAFT Goals for Terminal Mode 23 June 2001 3. Detail Discussion 3.1 legal support Terminal Mode MUST support the legal requirement same as required in classic fax by fax header or cover page with sender's ID and Time&date. 3.2 end-to-end SMTP session Terminal Mode should support SMTP for transmit and receive. ESMTP will be extended to support end-to-end connection between the transmitter and the receiver in the Terminal Mode. 3.3 One SMTP session Terminal Mode MUST support one end-to-end SMTP session for capability exchange, image transmission and confirmation. There were discussion about confirmation. The direct E2E communication doesn't need DSN confirmation because the sender knows the result of delivery confirmation when the communication finished. If the receiver can not accept the data, it will return to the sender error code such as 4xx or 5xx as e-mail server. After sending 250 to the sender for success of reception and before closing the SMTP session, the receiver will send an accurate confirmation in MDN. After printing, IFAX can send an accurate confirmation including the result of printing. 3.4 Proof of delivery/receipt "delivery confirmation" and "processing confirmation" should be requested in Terminal Mode. DSN will not be required for "delivery confirmation" on end-to-end SMTP. 3.5 Fall back When the transmitter can not connect SMTP to the receiver, the transmitter MAY send it by Simple Mode, EIFAX or FFPIM to the email server for the destination address, manually. 4. Acknowledgements The author would like to thank the ITU-T old SG8 members and the ITU-T new SG16 members for their contributions. The author also would like to thank Mr. Toyoda, Mr. Tamura and Mr. Wing who helped to extend my basic idea. Maeda Internet draft [Page 4] INTERNET-DRAFT Goals for Terminal Mode 23 June 2001 5.
