SP--DSNI-S--DSN
An interface of SP level (SP – DSN)
FBI (Fiber Bus Interface)
It Applies Synchronous Multiplexing Technique and Optical Fiber Technique to Implement the Interconnections of Modules .
It Uses Two Optical Fiber Lines to Transmit up to 16 Lines of 8mb/s PCM Signals
It Can Reduce Connection Wires and Increase Anti-interference Ability of the System, and to Reduce Mutual Cross Talks Among Wires.
FBI(Fiber Bus Interface)
Note :
When HW Lines 4~19 Are Used for Intra-module Unit
Connection,the FBI Board Must Be Replaced by the
DSNI.

•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.
