THE FEATURES OF THE ZXJ10 SWITCH
-----The Multi-module Forms an Exchange.
With a 2-level or 3-lever Networking Capability,
Module Can Further Carry Modules.
Two Cases:
• Level -1 Is Central Module
• Level -1 Is PSM

RLM:Remote subscriber line module , RSU
It is a subscriber unit used in a remote subscriber group .
•Each RLM is usually restricted to with in 960 subscriber lines.
•The way of connection between the PSM and RLM can be RDT board or RODT board.

•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 networkThe 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.
