Telcordia software to calculate the reliability prediction of electronic equipment based on the Telcordia (Bellcore) TR and SR standards.
.Standards based reliability prediction is a methodology for predictingthe reliability of a product by using failure rate estimates publishedin globally recognized standards. It is usually conducted during the concept and design phaseof product development, where test data are not yet available. With therelease of Version 9,now supports fourreliability prediction standards: MIL-HDBK-217F, Bellcore/Telcordia(SR-332), NSWC-07 and FIDES. This article focuses on the Bellcore/Telcordiastandard.
We will present an overview of the four versions of the standardthat are supported by the software, and then give an example that uses the latest version ofthe standard, Telcordia SSR-332 Issue 3. Bellcore/Telcordia StandardsThe Telcordia reliability prediction procedure has a long and distinguished history of use inthe telecommunications and electronics industry. During the past fifteen years, four versions ofthe standard have been published:. Bellcore TR-332 Issue 6 (1997). Telcordia SR-332 Issue 1 (2001). Telcordia SR-332 Issue 2 (2006).
Telcordia Sr 332 Handbook 2 Walkthrough
Telcordia SR-332 Issue 3 (2011)Each new version modifies the previous edition based on new data. Telcordia Issue 1made minor changes and updated the devicefailure rates published in Bellcore TR-332. In Telcordia Issue 2,several new devices were introduced and the generic device failure rateswere updated. In addition, the standard deviation of the generic failurerate for each device was provided so calculations for the upperconfidence bound of the failure rate were made possible.
