Shipboard Data Multiplex System AN/USQ...(V) T&E (Test and Evaluation) Management Plan. Recommended Test and Evaluation of the SDMS Engineering Development Model.

In response to ADO 32-A7X, NAVSEA has undertaken the development of a general-purpose Shipboard Data Multiplex System SDMS that will provide modular, flexible, single data interconnection for use in many ships and submarines. Instead of specific system designs requiring miles of unique cabling for each ship, SDMS meets information transfer needs with general-purpose multiplex cables installed according to a standard plan that does not vary with changes in a shipss electronics configuration.The SDMS provides an unusual approach towards multiplexing in that it is totally asynchronous and has no central point of control. The local control of data parameters plus the actively redundant architecture of SDMS results in a system with high reliability, no single point of failure, graceful degradation, and high survivability. These features, together with minimal intercompartmental cabling and standardization of user interfaces, result in a flexible and cost-effective information transfer system. This management plan sets forth the recommended program necessary for testing and evaluating the engineering development model EDM of SDMS.
