The Table5-3 provides alarm indicator descriptions for the mBSC DAS system. Alarm types for the Host
Unit and Remote Unit monitored by the NMS are included as well as optional components such as the
POI. The recommended category for the alarm indicator is included in column 3 of the table along with the
affected component. Critical alarms indicate system failures that disable the uplink or downlink operation.
Other categories, such as Major, may indicate impaired performance, but not the catastrophic system
failure or a specific RU node failure.
