Description
The power in the uplink (primarily
the Remote Unit) has exceeded the
defined threshold. This will cause
the LNA in the Remote Unit to
switch off until the overload
condition is removed.
It can be caused by uncontrolled
uplink power from mobiles or by
poor installation causing reduction
in Tx Rx isolation.
This relates primarily to the service
Module and is raised when the
downlink power from the connected
BTS or POI exceeds the specified
input level.
A unit that was present at the
application of Validate / Apply
Settings is no longer connected to
the system.
Description
The settings of the system need to
be confirmed by clicking Validate /
Apply Settings.
The output power requested at
System Setup cannot be achieved.
This will be due to a poor optical
link which requires too much
compensation (gain).
