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.
