| Summary: | 碩士 === 國立中央大學 === 資訊及電子工程研究所 === 83 === Since both facsimiles and computer networks are used widely,
various systems integrating them are developed. One of these
application areas is the integration of the e-mail and
facsimiles. The e-mail is the most popular textual delivery
system on computer networks, and almost installed on each
computer connecting with Internet. The message exchange between
the fax/phone and e-mail will enhance their messaging
capabilities. In the Distributed System Laboratory at the
National Central University, a new system with the MIME mail
and fax/phone has been proposed to fill the request for the
transmission of bi-directional multimedia messages. With the
help of the Remote Printing Experiment, a user can send
messages from Internet to the Public Switched Telephone Network
(PSTN). Furthermore, our system extends their work to make
users send multimedia messages from PSTN to Internet. In the
meantime, the Fax-MIME gateway was developed by University of
Ottawa in Canada. This system also uses the mechanism of the
Remote Printing Experiment to send messages from Internet to
PSTN. The gateway has the ability of bidirection MIME messaging
with the Binary File Transfer (BFT) protocol support. However,
BFT is not adopted widely by the fax machine manufacturers as
Group 3, so most fax machines don't support this standard, and
the message transmission of this gateway is still a single
direction for most end-users. By contrast, our system offers
multiple contact points: telephones, Group 3 fax machines and
computers to transmit messages containing text , image or audio
to the Internet recipients through PSTN. Finally, we believe
that our system meets a real user need: bidirection multimedia
messaging, a simple and user-friendly interface, and a
transparent and complete addressing scheme.
