For maximum safety, we recommend constantly monitoring the status of all optical rings. In the event of the first disruption of the optical ring the data is redirected to a backup route and the system continues to function. However, there can occur a second fault, after which, part of the system will be non-functioning. Event Management includes a variety of tools for early detection of faults. Moreover, it is able to monitor and control the (on / off) status of any ethernet or optical port.
