NEs supporting the alarm acknowledgment mechanism on 320G and 1600G devices

Question:
If alarms are generated, NEs of earlier versions report the alarms to the NMS only for three consecutive times regardless of whether the NMS receives the alarms or not. In the latest version, NEs establish an alarm acknowledgment mechanism with the NMS. Therefore, when alarms are generated, the NEs continuously report the alarms to the NMS until they receive acknowledgment information from the NMS. For 4.0 and 5.0 platforms, which NEs on 320G and 1600G devices support the alarm acknowledgement mechanism?
Answer:
On the 4.0 platform, NEs support the alarm acknowledgement mechanisms since 4.08.04.20P03. On the 5.0 platform, NEs support the alarm acknowledgement mechanisms since 5.08.03.10.
