MTBF figures
From Zenitel Wiki
MTBF (Mean Time Between failures) figures try to give a measure of the reliability of a system. There are 2 ways in which MTBF figures can be obtained:
- Calculation. There are a number of different standards for the calculation of MTBF figures, of which 217 Plus is one of the methods.
- Statistical information. MTBF figures can also be calculated form data gathered about failures in real installations. Of each electronic unit the number of hours in operation is reported at the moment of failure. When this is done over a sufficient large quantity of the same units a realistic ‘real life’ MTBF can be calculated. The MTBF of newly designed items can still be calculated this way by comparing them to existing items with a similar complexity.
The table below provides MTBF figures (where available) in 3 different ways (all figures are in hours):
- Statistical, in line with common practice
- 217 Plus, Ground Stationary, 25 degrees C
- 217 Plus, Naval Sheltered, 40 degrees C
For information how MTBF relates to percentage of equipment still in service after some years, see MTBF and spares
