R2 line signaling

Brazil Config 1 R2 signals are according to CCITT standard. See Table 32 for the Brazil Config 1

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.
