R2 line signaling

Brazil Config 2 R2 signals are according to CCITT standard. See
R2 signal definitions.

Note: CD bits are not used. They are set to 01 in transmit direction, and are ignored in receive direction.

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.
Table 38 shows the MFC signal configuration in the R2MFC MBM accessed through the CLI for
Brazil Config 2.
