Information Highway - Polycom MGC-100 Getting Started Manual

Information Highway

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 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.
