Mean Time Between Failure and System Availability
Mean Time Between Failure (MTBF) data is used to provide statistical information as to the length of time that should
expire before a particular card or system fails. This information is calculated using the following method:
Calculated MTBF - Expected elapsed time before failure occurs using the method defined in Telcordia TR-NWT-
000332-CORE. This is based on reliability of components and design factors.
Failure per million hours (Fpmh) identifies the predicted failure rate per one million hours (for every 1,000,000 hours of
operation, ―FITS number‖ of failures would be expected to occur) for a component of the system.
MTBF Table
The following table shows the MTBF characteristics of each major component of the system.
