The structure of background network

NT Server MP MP protocol TCP/IP router NT Client NT Client .. DDN PSTN/PSPDN NT Client NT Client NT Client

The structure of background network The Network Contain 3 Types of Nodes: Foreground Active/standby MP Background Servers(server) Background Maintenance Terminal(clients)

The structure of background network MP (foreground ) connects with background by the Ethernet. It uses the HUB to connect each other. The communication protocol is TCP/IP. The operating system of Sever and Client is WINDOWS NT

The structure of background network Each MP and the computer in background have a IP address respectively. The arrangement is as follows: 1~128 identify the active/standby Mps of the 64 modules(MP nodes) 129~133are background NT Server nodes 134~187 are background Client nodes 254 is for the specific alarm panel.
