Chapter 1Overview
This chapter describes the various functions of the SMG-400 system, its component parts, and
system specifications to provide you with a good understanding of the system.
Introduction to the SMG-400
SMG-400 VoIP (Voice over Internet Protocol) gateway system is a high performance H.323
compliantgatewayoptimized for voice communicationover the Internet.
SMG-400 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-400 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-400 provides local/remote CLI (Command Line Interface). To use SMG-400 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-400 enables easier
systemconfiguration evenif a user is not accustomed to the Gatewaysystem.

1-2 Chapter 1
Overview
SMG-400 Features
The SMG-400 system has the following major features.
PSTN Interfaces
The SMG-400 system provides the following PSTN interfaces for interoperability with PBX
(Private Branch eXchange) or KTS (Key Telephone System).
☞LOOP Analog Trunk Interface
☞SLC Analog Interface
VoIP Interfaces
VoIP is a technology that enables simultaneous transmission of both voice and data over the
Internet, and enables Internet telephony service. The SMG-400 system offers the following VoIP
interfaces.
☞H.323-V3 VoIP Interface
☞Gatekeeper Interface (RAS)
☞Real Time Internet Fax Support (FoIP)
Trunk Routing Functions
The SMG-400 system offers the following trunk functions including trunk routing, trunk tandem,
and access code control.
☞Trunk Routing
yLCR (Lease Cost Routing) code and route control
yDynamic rerouting depending on the traffic load of PSTN and Internet Protocol state
yRouting Table
☞Trunk Tandem
yVarious PSTN and VoIP trunks connection
yInteroperability among analog trunk, digital station, and VoIP network
☞Access Code Control
yIP address translation based on access code and prefix number

1-3
Call Processing Functions
The SMG-400 system provides the following call processing functions.
☞DTMF Signaling
☞DTMF Relay between PSTN and VoIP
☞CDR (Call Detail Record) Generation
☞RTP Traffic Channel Status Monitoring Functions (Delay, Loss, and Link Down)
System Management Functions
The SMG-400 system provides GUI interface, and a Standard Network Management Protocol
(SNMP) for easier management. The SMG-400 also provides the following system management
functions.
☞Web-based Management
☞Program change by TFTP Loading
☞DHCP Client (IP address allocation by DHCP server)
☞FTP, Telnet Interface
☞CLI (Command Line Interface)
PSTN Routing
The SMG-400 system provides a function called PSTN rerouting (or PSTN Detour). PSTN
rerouting is used to reroute a call set by a VOIP to PSTN network bypassing an IP network in the
case of havingpoor QoS(QualityofService), or detectingIP network beingbusy or disconnected
or in error.
