Equipment Management

5.2
The OptiX OSN 3500 is uniformly managed by the NM system. Through the Qx
interface or MML interface, the NM system can implement management,
maintenance and test to the whole optical transmission system in terms of fault,
performance, configuration and security. The NM system improves the quality of
network services, reduces the maintenance cost and ensures rational use of network
resources.
Huawei Technologies Co., Ltd. provides telecommunication operators with a whole
series of optical transmission systems, which can be used on networks of different
layers. To manage sub-network, area network or national network efficiently, the NM
system is required to feature basic operation and maintenance functions, and the
monitoring and management capability on the optical transmission network as well.
According to the Telecommunications Management Network (TMN) network
management hierarchical model, the telecommunication network management is
divided into network element layer (NEL), NE management layer (EML), network
management layer (NML), service management layer (SML) and business
management layer (BML). The NE management system manages NE equipments
within one subnet, while the NM system implements the network layer assignment,
fault monitoring, performance analysis, resource analysis, circuit dispatching, etc. in a
large-scale network.
To adapt to network management of different scales and levels, the OptiX iManager
series products of Huawei consists of the local maintenance terminal, NE
management system, regional network management system and network level NM
system. These products cover the applications of the TMN from the NE management
layer, subnet management layer to the network management layer, and contain part
of the service management layer functions. All the OptiX iManager series products
can perform uniform management on SDH, WDM and OSN equipments. With these
products, Huawei is able to provide telecommunication operators with a complete
package of network management solutions for single equipment, single service to
large scale and multi-service networks.
