AINS Support for Controllers
After the completion of a maintenance window, the controller can be removed from the maintenance state without manual intervention by configuring the Automatic-In-Service (AINS) state with a soak time period. After the expiry of the soak time period, the state automatically goes to the normal or the In-Service state.
AINS can be set or cleared on the controller using the automatic-in-service controller optics R/S/I/P hours x minutes y command in the EXEC XR mode.
RP/0/#automatic-in-service controller odu2 0/6/0/2 hours 0 minutes 15
The soak time can be configured when the controller is moved to the AINS state. The minimum soak time is 0 hours 15 minutes and the maximum is 48 hours. The soak time can be configured in intervals of 15 minutes. If a soak time is not specified, it defaults to eight hours. If the soak time is set to 0 using the automatic-in-service controller controller-name R/S/I/P hours 0 minutes 0 command , the AINS configuration on the controller is cleared.
The AINS configuration can be viewed using the show controllers controller-name R/S/I/P command.

The priority amongst the secondary administrative states are Maintenance > Automatic In-Service > In-Service (Normal). When the controller is put into maintenance, the soak timer is automatically paused and the soak timer status is moved to pending.

If a traffic impacting alarm is raised on the controller, the AINS soak timer is reset to the previously configured value or to eight hours if AINS was not previously configured. To transition from the AINS state to the in-service state, a clean soak period is mandatory with no traffic impacting alarms on the controller. New alarms are suppressed when the controller is in AINS state.
-
The AINS state is inherited by child controllers (OTU and ODU) from the parent controller .
-
Low order ODUs inherit configured soak timer values.
-
If a child controller is configured first with a higher soak timer value and then the parent controller is configured with a lower soak timer value, then the child controller inherits the parent value.
-
If the parent controller is configured first with a lower value and then the child controller is configured with a higher value, then the parent and child controllers retain their locally configured values and there is no inheritance.
-
If the child controller is configured first with a lower value and then parent controller is configured with a higher value, then the child controller inherits the parent controller value.
-
If the parent controller is configured with a higher value and then the child controller is configured with a lower value, the value is rejected as the soak time can be locally configured on the child controller but cannot be lesser than the parent controller.
