ToolKit Bellcore Module

The Bellcore / Telcordia Module calculates the reliability prediction of electronic equipment based on the Bellcore / Telcordia reliability prediction standards TR-332 and SR-332 (published by AT&T Bell Labs). These standards use a series of models for various categories of electronic, electrical and electro-mechanical components to predict steady-state failure rates and component reliability which are affected by environmental conditions, quality levels, electrical stress conditions and various other parameters. The models allow reliability prediction to be performed using three methods:

Method I: Parts Count
Method II: Combines Method I predictions with laboratory data
Method III: Predictions based on field data

Bellcore system

Module features include:

Multiple systems within the same project
Transfer to and from any other module
Redundancy modeling including hot standby
External Arrhenius temperature model for user defined failure rates
Linked Blocks: represent blocks with identical characteristics
Features common to all modules
