5.1 Network supervision
The network operator receives the alarms sent by the network equipment. With the aid of the the 9900LT
software applications, the operator can view and analyse the alarms and trigger the appropriate corrective
operations (see procedures below).
In the event of unsatisfactory results from the performance measurement programs, analyses may be made
to localise the implicated station and implement the necessary maintenance operations to restore original link
performance.
On detection of a fault, the operator should go to the faulty station. He should take a laptop PC enabling him
to configure, if required, certain system characteristics.

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) complies with installation
requirements (see section 3 of this Manual). In case of doubt, the suspect parts should be checked, taking all
precautions to avoid interrupting link data transmission.
