Question:
What is MTTF or MTTR info of offers?

Answer:

Availability = MTTF (Mean Time To Failure)
Reliability = MTBF (Mean Time Between Failures)
Maintainability = MTTR (Mean Time To Repair)
MTBF is what R&D(design) could decide based on component spec.
But MTTR is decided by maintenance schedule and device maintenance cycle, its different with different customer.
MTTF=MTBF/(MTBF+MTTR), so also related with site practice.
So we only have MTBF information.
