Chapter 4 - Hardware Description

Information Highway

The Information Highway is a high capacity TDM-type bus. It is used by both

the MGC+100 and the MGC+50. The Information Highway transfers

information from the Network Interface Modules to the MUX+ Modules and

from the MUX+ Modules to the Audio+, Video+ and Data Modules except

during IP calls. In IP calls (H.323 and SIP) the information is transferred

directly to the IP+ network module and from there to the Audio+, Video+ and

Data modules.

Powerplane

The MGC+100, as opposed to the MGC+50, uses a Powerplane. Up to three

Power Supply Modules can be plugged into the Powerplane. The Powerplane

and Power Supply Modules are designed to accommodate hot swapping of

power supplies.

In the MGC+50, there is one power supply, which is connected to the backplane

and fans via wire leads.
