This example demonstrates a network in which three SmartServers are used to create an IP-852
channel connecting three TP/FT-10 channels, each of which connects the devices installed on a
different floor in a building. The circled portion of the diagram represents the IP-852 channelthe
virtual, IP-based connection between the three SmartServers, the OpenLNS Server, and the IP-852
Configuration Server. An OpenLNS, LNS, or OpenLDV application can use this IP-852 channel to
communicate with the devices on all three of the TP/FT-10 channels connected to each of the three
SmartServers, and monitor and control the entire building.
A complete installation may contain many IP-852 devices attached to one IP-852 channel. Because the
IP-852 channel can exist on any IP network, a system may now span the entire globe as easily as it
once spanned a single building, as shown in the following figure.
