What is Telcordia SR-332?
Note: Bellcore (Bell Communications Research, a spin-off of AT&T Bell Labs) was the research arm of the Bell Operating Companies. Bellcore was purchased by SAIC in 1997. The purchase agreement required Bellcore to change its name: Bellcore became Telcordia Technologies in 1999. Ericsson acquired Telcordia in 2012.

Bellcore previously used MIL-HDBK-217 for their reliability predictions, but found that 217 gave pessimistic numbers for its commercial quality products. A few years ago (1985), Bellcore used 217 as a starting point, modified (and simplified) the models to better reflect their field experience, and developed the Bellcore reliability prediction procedure, which is applicable to commercial electronic products. Telcordia has continued the development of the reliability prediction procedure.

Most commercial electronic product companies are now choosing to use the Telcordia SR-332 handbook for their reliability predictions.

RelCalc V5.1-TELC3 implements the models of this Telcordia document:
"Reliability Prediction Procedure for Electronic Equipment"
Document Number SR-332, Issue 3
