The different types of Functional Modules are used to produce a variety of
configurations. In the MGC+50 up to eight individual Functional Modules
can be used to build the desired configuration. In the MGC+100, 16 modules
can be used.

Figure 4-10 shows the general design of the Functional Modules. The
components that are common to all Functional Modules are shown in detail in
the figure and are described in Table 4-6 on page 4-19.
