The NMS server implements the Manager function, the NE order
wire control board implements the Agent function, and various
line cards implement specific management actions.
The MNS server can communicate with the NE order wire control
board through the Ethernet interface or ECC protocol stack, thus
allowing the Manage to manage the Agent.
It does not directly send the message to the TAA board, TDM
line cards (including 2.5 G/622 M/155 M optical line boards, E1
electrical tributary board and 10M/100M Ethernet transparent
transmission board), ES line card and ATM line card.
The communication message between it and the line cards
should be processed and forwarded by the corresponding
module of the NE order wire control board.
The software module of the NE order wire control board saves
the software versions of all boards as well as all static
configuration databases in this NE.
During the initialization after power-on, the function modules of
the NOWC board access the necessary static configuration data
in the data base module.
On the contrary, during the power-on and initialization, the line
cards first load the line card software from the Flash to the
SDRAM for running. Then the boards obtain the static data of
the line cards from the NE order wire control board.
