Chapter 1Overview
This chapter describes the various functions of the SMG-3200 system, its component parts, and
system specifications to provide you with a good understanding of the system.
Introduction to the SMG-3200
SMG-3200 VoIP (Voice over Internet Protocol) gateway system is a high performance H.323
compliantgatewayoptimized for voice communicationover the Internet.
SMG-3200 enables transmission of both voice and FAX data from a PSTN (Public Switched
Telephone Network) through real-time data compression and protocol conversion. Therefore, it
enables seamless integration of voice and data networks, simple network architecture design and
considerable cost reduction in network infrastructure construction. Also, it can provide long-
distance and international telephone services at local telephone rates for users in an Internet or
Intranet environment.
Since SMG-3200 is designed based on hardware and software modules, it is easy to install.
Installation of trunks, subscriber linesor new software for additional features is possible,even during
operation if necessary.
SMG-3200 provides local/remote CLI (Command Line Interface). To use SMG-3200 after
installing the hardware, only a basic information configuration for system operation using CLI
commands is needed, while the remaining operatingenvironment configuration is automatically
configured using default values. Providing conversational type CLI, SMG-3200 enables easier
systemconfiguration evenif a user is not accustomed to the Gatewaysystem.
