MGC Hardware and Installation Manual
The MGC unit can contain different types of IP network cards. The Main Control Module operating system includes drivers for all of the cards. The Main Control Module’s operating system automatically detects the card type. If the card is correctly identified, the system starts up correctly. If the system fails to detect any card type, it will start up according to the card type definition in the system.cfg file.
The Main Control Module includes several connectors. These are connected to ports on the chassis. Two types of connectors on the rear panel provide connections from the MGC to various external systems. These systems include reservation systems, local or remote operator consoles, management systems and billing systems. One connector is a standard Ethernet LAN interface, which support operator workstations operating on LANs via TCP/ IP. The other connector is an

The Main Control Module Control Bus connects to the Functional Modules.
The C8M provides the interface between the Main Control Module and the Backplane. This module also generates the MCU clock. The operating system running on the Main Control Module uses the Processor’s internal clock interrupts to set up its
This feature does not correct any time difference between the MGC Manager’s clock (which is derived from the Windows operating system run on the operator workstation) and the MCU internal clock.
