SMS Text triggers Out-Of-Band connection
At Opengear the fastest growing segment of our business is the cellular enabled out-of-band solutions. Day after day, we are contacted by customers looking to replace POTS lines connected to an external modem that historically enabled remote admin access during an outage. When presented with a Cellular option to a POTS line solution the first idea to newcomers is “can i dial this like a modem?” Technically, yes we can however most carriers have stopped supportinig CSD equipment to allow cellular connection to answer like good old fashion modems. Some of these users feel that SMS texting to trigger the cellular radio signal is the best method for out-of-band access in their application. Technicians who once carried modems to access remote sites now rely on SMS text and tablet technology to serve customers in a timely fashion and ensure uptime. The flexibility of our products to meet and scale to any demand is really a fun process to watch in action as our products have near limitless customization.
Customers who wish to contact our devices via SMS text to raise and lower the cellular radio signal can find this solution in a Knowledgebase article here.
Oh wait, what if we forget to SMS the Opengear to drop the connection after we are finished troubleshooting?
Gotcha covered with an Idle timeout script. As well our device can be queried via SMS to report back the dynamically assigned IP address and cellular signal strength.
