The system operator receives the alarms sent by the network equipment. With the aid of the the 7390LT
software applications, the operator can view and analyze the alarms and trigger the appropriate
operations (see specific procedures below).
On detection of a fault, the operator analyzes alarms and starts the suitable maintenance actions.
5.2 – Preventive maintenance
This maintenance is carried out, either during a corrective maintenance inspection, or during a periodic
inspection, on all station equipment. It consists in inspecting the units and their interconnections
(connectors, cables, sockets, etc.) and ensuring that the environment of the Indoor Units (NTs and RTs)
complies with installation requirements (see § 3 – Installation of the X-Pol RT’s A7390 Terminal Station).
It is essential to check connectors and splitters state with earthing.
In case of doubt, the suspect parts should be checked, taking all precautions to avoid interrupting link
data transmission.
