Description: For values 1 to 8 :
   this variable gives details on transitory failures 
of a CU (Control Unit) card.
Other values :
   this variable gives details on failures on signals
from or to a BBSYN card.
For the other cards, this variable is not significant;
see adnEquipTrapCause to know the reason of the last 
failure.
The value zero indicates that there is no such type 
of failure.
