As with all prediction standards, SR-332 should not be viewed as a substitute for actual reliability testing. Predictions provide a design-phase estimate that should be validated through appropriate qualification testing once prototypes become available.
The Telcordia SR332 standard has undergone several revisions since its initial publication. Issue 3 is the latest version of the standard, which was published in 2001. The main changes and updates introduced in Issue 3 include: "Of course it is

Telcordia SR-332, first published as Bellcore TR-332 in the 1980s, is the telecommunications industry's answer to the overly pessimistic predictions of the military-standard . Originally, Bellcore used MIL-HDBK-217 for its predictions but found it generated failure rates far higher than what was observed in the commercial field. Consequently, Telcordia (formerly Bellcore) took the 217 framework as a starting point, significantly modified and simplified the models, and tailored them to better reflect real-world field experience for commercial-grade electronic products.
