SR-332 has its roots in the work of Bellcore (Bell Communications Research), the research arm of the Bell Operating Companies spun off from AT&T Bell Labs. It was developed as a more realistic alternative to the military-focused MIL-HDBK-217, which was found to produce overly pessimistic (i.e., higher failure rate) predictions for modern, high-quality commercial electronics. After Bellcore was purchased, it was required to change its name, becoming Telcordia Technologies in 1999; the company was later acquired by Ericsson in 2012.
