Informational
Some events also cause alarms and are sub-divided as described in the following sections. All these
event types are recorded in the log files accessible in the Configuration
13.1.1 Loss of Service
This occurs when the Primary Hub detects an event that will result in the complete loss of 1 or more
services in at least 1 RU location, e.g. a link calibration failure, Overload "Safe Mode", RU
communication timeout, thermal shutdown, etc.
A typical example of a Loss of Service alarm occurs when a Remote Unit is disconnected from the
system.
The log file will show the following type of behavior.
