B.3 Service State Transitions
This section describes the transition from one service state to the next for cards, ports, and
cross-connects. A service state transition is based on the action performed on the entity.
Note When an entity is put in the OOS,MT administrative state, the ONS 15454 suppresses all standing alarms
on that entity. All alarms and events appear on the Conditions tab. You can change this behavior for the
LPBKFACILITY and LPBKTERMINAL alarms. To display these alarms on the Alarms tab, set the
NODE.general.ReportLoopbackConditionsOnOOS-MTPorts to TRUE on the NE Defaults tab.

Table B-4 lists card service state transitions.
