The Overview of the Prediction Module page contains a description of the features available in Reliability Workbench for building a Telcordia SR-332 model.

It can also be used directly by telecommunications service providers for product reliability evaluation. The Telcordia standard also documents a recommended method for predicting serial system hardware reliability. The Prediction Module automatically calculates the First Year Multiplier based on specified system, unit and device burn-in times and temperatures. The component tr-3332 tested under temperatures ofand Kelvin. This First Year Multiplier (FYM) is influenced by burn-in times and temperatures. The failure rate during this wear-in phase is expressed as a multiplying factor operating on the predicted steady-state failure rate. Test duration 1s 3 File Name: lfeighthbrick.PDF Rev:, 93 RH, 4 days 50 of samples powered at 10 load and 50 unpowered 3 axes, 5 sweeps per axis, (output remains within ☙) Level 3, (output within. The Telcordia SR-332 Standard also provides models for predicting the failure rates of units and devices during the first year of operation. Telcordia SR-332 Issue 3 (2011) Each new version modifies the previous edition based on new. Method III provides predictions based on combining field tracking data with Parts Count data.Īll three methods are handled by the Reliability Workbench Prediction Module.Method II provides predictions based on combining laboratory test data with Parts Count data.

Method I provides predictions based on a Parts Count procedure.The Telcordia Standard allows reliability predictions to be performed using three methods: Issue 4 of SR-332, Reliability Prediction Procedure for Electronic Equipment, replaces Issue 3, and is a module of. The Telcordia SR-332 module was created using Telcordia SR-332, originally the Bell Laboratories Bellcore standard for the reliability prediction of commercial electronic components.
