An update package is composed of several dwl files that will be installed by the update agent. A CRC check is done by the update agent before installing the update package. So if the update package has been corrupted after its creation, it won't be installed. But if one of the dwl file used at the update package creation has a bad content (not a real dwl file, corrupted dwl file...), the update agent will not detect the bad file before beginning the installation. That-is to-say that some dwl files can be installed before detecting the bad content.

Using AMS, a parameter can be configured to send an alert to AMS when a specific value is reached. If the triggered value is reached but the Airprime is not registered on the network, the alert will be sent when Airprime is registered again. However in this case the reported value could be current one i.e. the last updated value (if the parameter value was changed between the moment triggered was reached and the report).
