A close-up view of the auxiliary connector label, as shown in Figure 6-5, indicates the short signal name

for each connection point. Deﬁ nitions for these signals can be found in the SR-39-1 subrack manual.

Extra General Purpose Input / Output connectors (GPIO) that can be used for different functions

depending on the control card are listed to the right of the connectors. For example, the CI-BC-4E base

controller uses these lines for auxiliary audio inputs / outputs and auxiliary COR / PTT connections.

The CI-PM-3 paging modulator uses these signal lines for connecting A/D select lines, 2-level and

4-level data, etc. The custom functions of these connectors will be marked in the blank space next to

the signal name.
