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.
MFE signaling
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.
Table 136: MFE Frequency values
on page 297 lists the forward and backward frequencies
for MFE. The one backward signal for MFE is referred to as the "control" frequency.
