MGC

Description

Component

 

 

 

Control Module

The Main Control Module performs the conference setup

 

and termination and resource allocation in both the

 

MGC-100 and the MGC-50.

 

 

Backplane

The backplane is an electronic circuit board into which

 

The Network Interface Module, the Main Control Module,

 

Functional Modules, and I/O cards are plugged so the

 

various modules can communicate with each other. The

 

Backplane is based on the “universal slot” concept, where

 

any card can be inserted in any slot.

 

 

Power Plane

The Power Plane is a conducting layer providing power to

 

the components. It is part of the Backplane and is

 

designed to accommodate hot swapping of power

 

supplies.

 

 

Power Supply

The Power Supply Module is located underneath the Main

Modules

Control Module and the Functional Modules and is

 

connected to the backplane. It provides power to the

 

Backplane by means of a power bus. Both MGC units

 

(MGC-100 and MGC-50) operate at 100-240 volts AC 50/

 

60 Hz.

 

 

Fans

Three (MGC-100) or two (MGC-50) fans are mounted at

 

the bottom of the rear panel.

 

 

Alarms Port

In the MGC-100 an Alarms port is located on the Main

 

Control Module. The dry contacts on the rear panel of the

 

MGC-100 are for connecting to the customer’s alarm

 

system.
