Overview  
Before you install LiveGateway, make sure LiveManager (version 3.1) or other H.323 Gatekeeper has been 
installed on the network and LiveLAN (version 3.0 or later) or other H.323 client, has been installed on the 
client PCs. Review the following information before you begin your LiveGateway upgrade or new installation.  
 
What is LiveGateway? 
LiveGateway is a bi-directional H.320/H.323-compliant gateway that provides LiveLAN and other H.323-
compliant clients access to H.320-compliant systems and other LiveLAN clients across an Integrated Services 
Digital Network (ISDN) WAN.  
LiveGateway includes a full-length ISA/EISA board and a server application installed on a Windows NT 
TCP/IP server and, if you are using PictureTel LiveManager, an optional LiveGateway Console integrated 
within and managed through LiveManager via SNMP (Simple Network Management Protocol). By using this 
LiveGateway Console, a LAN administrator can test, troubleshoot, and configure the ISDN network 
characteristics of the LiveGateway(s) installed throughout the network.
