Users can choose single-mode or multimode optical modules as required, thus
facilitating maintenance.
Orderwire phone function is provided to ensure dedicated communication
channels for administrators at various stations.
By means of the NM system, the running and alarm status of the equipment at all
stations on the network are dynamically monitored.
In-service upgrade of board software and NE software is supported. Board
software and field programmable gate array (FPGA) supports remote loading, and
provides the functions of error prevention loading and resume download.
With remote maintenance function, the maintenance personnel can remotely
maintain the OptiX OSN 7500 through PSTN when the equipment goes faulty.
The PDH processing board provides pseudo-random code test function which

Administration
The OptiX OSN 7500 is uniformly managed by the iManager series transmission
network management system (NM system for short). Through the Qx interface or
human-machine language (MML) interface, the NM system can manage, maintain
and test the entire optical transmission system in terms of fault, performance,
configuration and security. The NM system improves the quality of network services,
lowers the maintenance cost and ensures rational use of network resources.
