Earth station interface for demand assignment applications
Abstract
The ESI interface with a message processor for Bolt Beranek and Newman called the PSAT. M/A COM LINKABIT does not have a PSAT, but design verification testing must be performed in order to ensure the enhancements performed under this contract meet the requirements set forth in the proposal. In addition, each of the six ESI's produced will require the performance of an Acceptance Test Procedure prior to shipment. M/A-COM LINKABIT has proposed the design and construction of a PSAT Emulator which could exercise the ESI in a manner which approximates the PSAT well enough to verify operational status. The PSAT Emulator is designed around a Hewlett Packard 9836 desktop computer, whose principal means of communication with the ESI will be through an Emulator Interface Circuit Card Assembly (CCA). The design of the Emulator CCA is a substantial task and is now underway. This Technical Report discusses the design requirements for that CCA and will, we hope, impart some overall understanding of the PSAT Emulator. It should also be noted that BB&N is producing a new message processor, the BSAT, which streamlines message handling protocols for improved channel throughput.
