Install a Firmware Update using AT&T Communication Manager 7.1
IMPORTANT: To use the Install Firmware feature in ACM, firmware must be hosted on the Enterprise Configuration Service (ECS) server. Currently, AT&T does not host firmware in ECS so it will be necessary to download and install firmware updates directly from the manufacturer's website.
Updates to modem firmware (the device's internal operating software) are generally not downloaded as part of Communication Manager's normal software update process, but they can be. If an update is received, users will be asked whether to apply the update immediately or defer the update until later. If defer is chosen, the update can be applied by performing the following:
Click Tools > Settings.
Click the Updates tab.
Click Install Firmware. NOTE: If no updates are available the button will be grayed out.
