Service State Transitions
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 locked, maintenance administrative state, the ONS 15310-MA SDH
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.
