The exact meaning of each MFC signal number (1-15) within each level can 
be programmed separately for each trunk route using MFC. This 
programming can be done by the customer and allows users to suit the needs 
of each MFC-equipped trunk route.
Each MFC-equipped trunk route is associated with a data block that contains 
the MFC signal functions supported for that route. Up to 127 such tables can 
be defined for an Option 11C system.
