Rather than reporting alarms over IP, simply configure your wireless RTU to send SMS alarm notifications to your SMS Receiver. The SMS Receiver then parses the SMS Notification and forwards an SNMP trap to your T/Mon or alarm master station over LAN.
Reporting alarms via SMS rather than IP allows you to bypass the traditional hassles of wireless IP-based alarm reporting. One SMS Receiver can report alarms for multiple RTUs as well, allowing you to cheaply and easily employ wireless RTUs or establish a backup alarm-reporting path over wireless devices.
