Communications Support for Area A and Request/Reply

摘要

Service A communication requirements were analyzed to determine the optimal communications support strategy, with the National Airspace Data Interchange Network (NADIN) integration as one of the primary alternatives to be evaluated. That analysis yielded the following conclusions: integration of Service A into NADIN will reduce monthly leased line recurring costs; NADIN use will result in little or no increase in total present value cost; Service A integration into NADIN is not feasible prior to WMSC replacement; WMSC Replacement design will be simplified by use of NADIN support for Service A; and NADIN will improve Service A performance by permitting cost effective circuit reconfiguration. In addition, the analysis determined detailed enhancements to NADIN required to support Service A while adequately maintaining other NADIN traffic.
