Reliability

The Mean Time Between Failures (MTBF) prediction is calculated using component and
subassembly random failure rates. The calculation is based on the Telcordia
"Reliability Prediction Procedure for Electronic Equipment" SR-332 Issue 1, an update
of Bellcore TR-332, Issue 6. 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
221,007.51 hours.
