This document includes the following sections:
Modem firmware is downloaded to the modems at startup. A version of firmware is always bundled with the Cisco IOS image. A separate file can be stored in Flash memory to override this firmware with one that contains newer features. If the router finds more than one version of modem firmware at startup, it automatically loads the latest version.
