Default MTBF MTTR

I'm having trouble understanding the difference between MTTR and MTBF...

I am trying to model a conveyor where frequent stoppages occur on average once an hour (largely due to jams) -- no information is given on the type of distribution. And the time between belt stop and belt start for the last 50 occurrences follow an erlang distribution with a location value of 0, and a scale value 0.17, shape value of 21 and random number stream 1

Then is is okay to say (using the tool box) that:

MTBF follows an exponential distribution with scale value 60

MTTR follows erlang - with the values given above

Thanks

Lulu
