MGC-50/MGC-100 Getting Started Guide

iv

Before You Begin

This Getting Started Guide provides information on the in stallation and
basic operation of your MGC-50/100. For more information on def ining and
running conferences, defining IVR services and managing the system, refer
to the MGC Manager User’s Guide Volumes I & II and the MGC
Administrator’s Guide included with the system . Re ferences to the relevant
chapters of these guides are included throughout this Getting Started Guide.

This is an example of the notes that you may encounter throughout this guide.

System Overview

The MGC-50 and MGC-100 are high performance, high capacity multi­network solutions that provides you with feature-rich, and easy-to-use
multipoint voice, video and gateway conferencing.

The system meets International Telecommunication Union ­Telecommunication Standardization Sector, (ITU-T, formerly CCITT)
standards for multipoint multimedia bridging devices, and meets ETSI
standards for telecommunication products. The MGC-100 DC also meets
the NEBS Compliant St andard (when so o rdered) for our clien ts based in the
United States.

The flexible architecture in the system is designed to accommodate users’
changing multipoint needs. This system utilizes a modular “universal slot”
platform that allows the formation of different configurations based on
users’ individual port capacity and functionality requirements.

Description

The Functional Modules, also known as cards, perform
the various audio, video, and data processing functions
for the MGC unit. Both the MGC-100 and the MGC-50
use the same functional modules.Any module can be
inserted into any slot and servicing can be performed
while the system is in operation. The MGC-100 can
contain up to 16 Functi onal Mod ules and the MGC -50 can
contain up to 8 Functional Modules.

Input/Output (I/O) Cards connect the Functional Modules
to external systems and networks.

The MGC-50/MGC-100 requires basic configuration before you can start
running conferences.

Initial IP Configuration

The system is shipped with a default IP address: 129.254.4.8. Ordinarily,
you need to change the MCU’s default IP address to the IP address
appropriate for the site's LAN. This section describes how to modify it using
a monitor and terminal to connect directly to the MCU.

To modify the MCU default IP address to the site’s IP address:

1. Remove the Main Control Module cover.

3. Insert the DOS diskette into the MCU diskette drive.

4. Reset the MCU (by turning it off and then on), or if it is turned off, turn it

on. The command line is displayed.

5. Type C:\>dir mcu\cfg and press Enter.

6. Type C:\>\mcu\cfg>edit lan.cfg and press Enter.

The Edit screen opens displaying the IP configuration parameters.

7. Move the cursor to the appropriate line and enter the new IP Address.

If required, modify the Subnet Mask and the Default Gateway values.

8. Save the new IP configuration and exit the DOS editor.

9. Disconnect the monitor and keyboard from the MCU, and mount the

Main Control Module cover back to its place.

10. Restart the MCU.
