Data communications
Article Abstract:
Significant 1991-1992 trends and events in data communications include a blending of data and telecommunications technologies, implementation of frame relay technologies, efforts to link local area networks (LANs) to switched multimegabit data service (SMDS), implementation of 45M-bps backbone networks for the NSFnet research and education network and developments in Fiber Distributed Data Interface (FDDI) I and II standards. There were also a number of mergers, alliances and joint ventures, particularly in the development of links between LANs and SMDS. Several companies announced frame relay products in 1991, with even more firms promising implementations in 1992. The new NSFnet T3 backbone network links over 2300 university, government and industry networks. 47 vendors displayed FDDI products at the Interop 91 conference despite the fact that there has not been a resolution of which network management protocols to use and which twisted-pair wire media are going to be the FDDI standards. FDDI-II was proposed as a new ANSI standard that would accommodate integrated multimedia transmission.

The universal data connection
Article Abstract:
The communications world is working toward a universal standard for data and voice communications. The result will be a universal data connection, enabling the simultaneous translation of coded data, such as screen graphics, and voice communication. Networks such as this are called integrated-services digital networks (ISDN) and are expected to evolve from the digital telephone networks of several countries. Such networks will eliminate the cost and inconvenience of separate networks. The International Telephone and Telegraph Consultative Committee (CCITT), an organization of the United Nations, has formulated recommendations that define standardized interfaces that will make ISDN service as available as electric power is today. ISDN will be based on the OSI model. The introduction of the ISDN will certainly create a demand for new products, while phasing out older ones.
