The MGC Unit is made up of:
• Main Control Module, located at the top left of the unit when viewed
from the front
• Functional Modules, located to the right of the Main Control Module
when the unit is viewed from the front
• Power Supply Module, located underneath the Main Control Module and
Functional Modules
• Input/Output cards, located behind the backplane opposite the Functional
Modules.
The various modules communicate with each other via the Backplane. The
Control Bus and Information Highway are implemented on the Backplane.
