Abstract

The aim of this work is to characterize and develop a model for the determination of the cooling reliability of a mobile switching centre. From the analysis done with the reliability block diagram models (RBD), it was observed that the combined cooling reliability, MTBF and failure rate (λ) is 58.54%, 1389hrs and 0.000719704 respectively. Further checks on the combined cooling reliability gave 83.53% at 250hrs for the same failure rate which calls for urgent and stringent maintenance programs developed for the 250hrs cycle in addition to the already existing 744hrs cycle. This should be proactively applied to the cooling units on a need basis to increase the MTBF and the reliability of the older units to 99.982% required for high performance and public safety as specified by ANSI/TIA, especially during the heat season of the year.
