Our network management software provides powerful fault, configuration, inventory, performance and security management of our OSA 5335 through an intuitive graphical user interface, either locally or from a remote location. Results can be compared to standard masks and trigger alarms when limits are exceeded. All results are forwarded to the network management system for display, user validation and storage. Local alarm indication is provided by means of an internal buzzer, electrical relay contacts and status LEDs on the front panel.
