MFC Register Signaling

MFC signal definitions depends on the stage and the direction of the call; there are four tables of 15 signals each: the first stage uses I signals forward and A signals backward, and the second stage uses II signals forward and B signals backward. The meaning of the signals can also be different when being transmitted or received. Meanings of the MFC signals are configurable. MFC signal tables are part of the country-specific parameters.
