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

57. 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

58. 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.
