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.
The NT5K21 XMFC/MFE card can be programmed for MFE signaling
which is used mainly in France. MFE is much the same as MFC except it has
its own set of forward and backward signals.
