    – 10 minutes. Changing the interval as well as learning the current value is only possible via AT commands. When operating with the iRZ Collector specialized server, the modem sends a keepalive packet to the iRZ Collector server to verify connection if data transmission is not available for over a minute. If there is no re- sponse to the keepalive packets, the server clears the connection.
