17.1 INTRODUCTION
The RFL 9780 I/O modules serve as an interface for input and output signals between the RFL 9780
and the line coupling equipment. There are seven basic types of I/O modules that can be used with the
RFL 9780. The rear panel views of these are shown in Figure 17-1.
There are twelve types of Line I/O modules available. The rear panel views of these are shown in
Figure 17-2. Table 17-1 shows the various applications of all RFL 9780 I/O modules presently
available.
NOTE
Chassis power must be turned OFF before removing or installing
any RFL 9780 I/O modules.
