These periods are expressed in time units (microseconds) while 40 and 12
are the number of symbol durations these periods will last. We need to
multiply them both with the symbol_duration in order to get these
values in microseconds.

As mentioned in the discussion on the other thread I ripped this one out 
and applied it as fix to the wpan tree. Thanks!
