Sending Alarms Via Satellite

Optima Alarms-Uplink Mode

Learn how off-grid site alarms are processed, compressed, then sent via satellite to the RCS — where the original SNMP alarms are regenerated and sent on to your NMS.


1 Sending alarms via satellite links can be an expensive proposition. That is why Optima uses a unique compression method. It reduces the size of alarm messages by a factor of 40 or more. Once reduced to the absolute minimum, the alarms are ready for transport.


2 The scheduler makes sure the messages get queued up — and sent to the LEO satellite as soon as the alarms are ready for transport. It guarantees that there are no duplicates or missed alarms.


3 In turn, the alarms are sent on to the earth station. This gateway receives and logs all notifications as they come in. It catalogs the alarms from each of the remote sites, holding them ready for retrieval.


4 A special Optima Remote Commander Server (RCS) task polls the gateway. It securely retrieves all pending alarm notifications. It verifies and authenticates the retrieved messages to ensure authenticity.


5 The Optima RCS then reconstitutes the original SNMP trap or alarm notification. It follows Optima’s long established MIB format. This means no extra work or integration required — the NMS at the customer’s end accepts the alarm as if it was sent directly.
