Commission (FCC)
Part 15: Class A Statement. This equipment has
been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC
Rules. Test limits are designed to provide reasonable
protection against harmful interference when the
equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate
radio-frequency energy and, if not installed and used
in accordance with the instruction manuals, may
cause harmful interference to radio communications.
Operation of this equipment in a residential area is
likely to cause harmful interference, in which case the
user will be required to correct the interference at his
or her own expense.

Before You Begin
This Getting Started Guide provides information on the installation and
basic operation of your MGC-50/100. For more information on defining 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. References to the relevant
chapters of these guides are included throughout this Getting Started Guide.
System Overview
The MGC-50 and MGC-100 are high performance, high capacity multi-
network 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 Standard (when so ordered) for our clients 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.
This is an example of the notes that you may encounter throughout this guide.
