Software Structure

The software system of the ZXA10 S300 consists of five parts:

Software Module of NOWC Board

Software Module of Transmission Convergence Board
Software Module of TDM Line Card
Subsystem of EOS Software
Subsystem of RPR Software
Software Module of NOWC Board
During the initialization, the NOWC board first loads the
database from the Flash to the memory and configures it to the
corresponding modules and line cards. Meanwhile, it obtains the
time postmark of the static configuration data from the
transmission NMS SMN through the Ethernet interface or ECC
protocol stack. If the static configuration data in the NOWC Flash
is different from the postmark in the SMN, the NOWC software
will obtain the database with different time postmarks from the
SMN, write it into the Flash and reconfigure it to the modules
and line cards.
After storing the static configuration data of the whole NE, the
NOWC board software can work independent of the SMN. The
NOWC board software has various functions, including alarm
management, performance
management, database management, processing and forwarding
of the ECC messages and processing of order wire in the NE. The
module structure of the NOWC board software is shown in Figure
