Through the hardware interface provided by the SCC board, the communication
module transmits the OAM&P information and exchanges management information
between the NM system and NEs, and between NEs themselves. It consists of
network communication module, serial communication module and ECC
communication module.
Database management module
This module is an organic component of the NE software, composed of database and
management system. Database comprises several sub databases, including network
database, alarm database, performance database and equipment database. The
management system manages and accesses the data in the database.
5.4 Board Software
The board software runs on each board, managing, monitoring and controlling the
operation of the board. It receives the command issued from the NE software and
reports the board status to the NE software through performance and alarm events.
Its specific functions include: alarm management, performance management,
configuration management and communication management and so on. It can
directly control the functional circuits in corresponding boards and implement ITU-T
compliant specific functions of the NE.
The board software can be classified into the following types: line software,
cross-connect software, clock software and orderwire software.
5.5 NM System
The NM system implements a unified management over the optical transmission
network, and maintains all ION, SDH, Metro, DWDM NE equipment in the network. In
compliance with ITU-T Recommendation, it is a network management system
integrating standard management information model and object-oriented
management technology. It exchanges information with NE software through the
communication module to implement monitoring and management over the network
equipment.
The NM software runs on a workstation or PC, managing the equipment and the
transmission network. It enables the user to operate, maintain and manage the
transmission equipment. The management functions of the NM software include:
Alarm management: Collect, prompt, filter, browse, acknowledge, check, clear, and
statistics in real time; fulfill alarm insertion, alarm correlation analysis and fault
diagnosis.
Performance management: Set performance monitoring; browse, analyze and
print performance data; forecast medium-term and long-term performance; and
reset performance register.
