B.3 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 15600 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.ReportLoopbackConditionsOnUnlocked,MaintenancePorts to TRUE
on the NE Defaults tab.
B.3.1 Card Service State Transitions
lists card service state transitions.
Locked,disabled
Removes the entity from service and disables it.
Locked,maintenance
Removes the entity from service for maintenance.
