This paper discusses Australia's two packet-switching networks, AUSTPAC and MIDAS, which are used for data transmissions with other computers located within Australia or between overseas destinations. Although the facilities of both are similar, a comparison of their services based on traffic volume, connection, registration, and rental charges is made for the benefit of those unacquainted with technical and communication terms. AUSTPAC is the major focus of this paper, which discusses Deakin University's preference for AUSTPAC to provide low-cost database searches for students, and suggestions for the management functions for its implementation; an AUSTPAC link-up between Deakin and the Open University (OU) in the United Kingdom for teaching master courses, use of electronic mail, and other administrative functions, use of videotex systems for general information dissemination, and the design of and access to computerized research and bibliographical databases; the AUSTPAC billing software and plans for future computer facilities for staff and student access; general procedures for accessing AUSTPAC; an explanation of basic concepts and technical aspects of AUSTPAC's Packet Assembler/Disassembly (PAD) facility for packet-switching; variables for successful usage of AUSTPAC; problems encountered in the 1985 AUSTPAC trials; computer-mediated communications and educational use; and staff and student development in the use of computer technology. Several tables are provided for illustrative purposes. (DJR)
