Technical Reference 2.7 Reliability The Mean Time Between Failures (MTBF) prediction is calculated using a parts count method. The calculation is based on the Telcordia SR-332, Method I Case 1 50% electrical stress, 55 ºC ambient. The MTBF prediction is used to estimate repair rates and spare parts requirements. The MTBF data is calculated from predicted data at 55 ºC. The MTBF for the board is 61,582 hours. 2.8 Environmental Table 26 lists the environmental specifications for the board. Table 26.
