B.3 Service State Transitions
B.3 Service State Transitions
This section describes the transition from one service state to the next state for DWDM shelves, cards,
optical payload ports, OSC ports, OCHNCs, and transponder/muxponder cards and ports. A service state
transition is based on the action performed on the entity and any autonomous activity.
Note When an entity is put in the OOS,MT administrative state, the ONS node 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 (ANSI) or
NODE.general.ReportLoopbackConditionsOnPortsInLocked,Maintenance (ETSI) to TRUE on the NE
Defaults tab.
B.3.1 DWDM Shelf Service State Transitions
Table B-4 lists ANSI and ETSI service state transitions for shelf entities.
OOS,DSBLD Locked,disabled Removes the entity from service and disables it.
OOS,MT Locked,maintenance Removes the entity from service for maintenance.
