Communications Support for Flight Data Entry and Printout Terminals

摘要

The FDEP service, as it is to be upgraded under the FDIO Program, was analyzed to determine the optimal communications support strategy. That analysis yielded the following conclusions; integration of FDEP into NADIN is more economical than independent operation of FDEP, provision of local switching for FDEP messages in the NADIN concentrators should prove economical as more services are absorbed by NADIN, and procurement of FDIO equipment that would not be used when FDEP is integrated into NADIN should be avoided unless the timely upgrading of FDEP would be otherwise jeopardized. The analysis also produced detailed designs for local access FDEP circuits and identified specific enhancements required for NADIN if FDEP is to be absorbed. (Author)
