Abstract
The DSN Discrepancy Report System records all outages of DSN Data Systems that occur during mission support operations, The recorded outages of the Telemetry Data System for 1981 through 1983 were tabulated and analyzed. The analysis developed availability characteristics of the Telemetry Data System and several of its major elements, including, in particular, the Traveling Wave Maser (TWM) Assemblies. The principal objective of the work was to provide a comparison of availability characteristics of the TWM Assemblies with those of other DSN subsystems and assemblies. For the three-year period, the Availability of the Telemetry Data System is 99.03%, and its Mean Time to Restore Service is 0.9 hours; the Availability of the TWM Assemblies is 99.83%, and their Mean Time to Restore Service is 2.5 hours.
