Telcordia
The Bellcore/Telcordia standards (Reliability Prediction Procedure for Electronic Equipment) provide reliability prediction models for electronic components in commercial applications. Lambda Predict supports four versions of the standard, including:
These standards provide a choice of three methods for calculating the steady-state failure rate. Method I (also known as the Black Box method) uses the generic failure rates defined by the Bellcore/Telcordia standards and the pi factors. Method II allows you to supplement the black box calculations with real data that you've obtained from testing, while Method III considers real data obtained from an identical or similar item operating in the field.
