At Brookhaven National Laboratory data telecommunication for remote job entry, interactive time sharing, networking, graphics, and special purpose links became increasingly important--they now rival the more traditional over-the-counter traffic. The BNL Central Scientific Computing Facility (CSCF) responded to this need with a number of developments. The latest and most comprehensive of these is a ''front-end'' communications system built around MODCOMP II computers. To put this project into its proper framework, some historical background is presented describing predecessor systems, the development of specifications, and the factors considered in the decision to turn to MODCOMP. The hardware is based around dual MODCOMP II-233 processors with a specially developed link to the larger CSCF machines, two Control Data 6600 computers and one CDC 7600. The MODCOMP software is based upon an existing system developed by Chrysler Corporation, running under MAXCOM. On the Control Data side Scope 3.4/INTERCOM 4 is used as a basis. The developments and modifications, both hardware and software, necessary for these components to meet Brookhaven's specifications are described. Certain related special-purpose data link applications are described. Among them are a research project in national resource sharing networks using ARPANET, and a connection to the National Weather Service machines in Suitland, Maryland, using the bit-oriented protocol ADCCP. Future goals are briefly presented. 2 figures.
