R2 line signaling

Mexico Config 2 R2 signals are according to CCITT standard. See Table 31 for the Mexico Config 2 R2 signal definitions.

Table 31 Mexico Config 2 R2 A/B signals

Forward				Backward

Signal	A	B		Signal	A	B


Idle	1	0		Idle	1	0

Seize	0	0		Seize acknowledge	1	1

Clear forward	1	0		Answer	0	1

				Clear back	1	1

				Block	1	1

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 32 shows the MFC signal configuration in the R2MFC MBM accessed through the CLI for Mexico Config 2. Table 33 on page 97 shows the MFC transmitted signal configuration in the R2MFC MBM accessed through the CLI for Mexico Config 2. These values are preconfigured by the faceplate DIP switches as shown in Figure 30 on page 92. See Chapter 7, “Command Line Interface (CLI),” on page 73 for information on the CLI.
