This paper deals with the reliability analysis of a 3-unit subsystem of a cable plant. To facilitate the analysis, ten years maintenance data of the subsystem is collected and the states transition table for the subsystem is developed. Reliability indices of the subsystem such as mean time to failure, availability, expected number of repairs and expected busy period of the repairman are estimated using semiMarkov processes and regenerative point techniques. Simulation is carried out to demonstrate the effect of varying failure/repair rates on the subsystem reliability.
