Cisco Analog Modem Firmware Folheto

2 Release Notes for Analog Modem Firmware Version 1.0.1

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. 

The firmware version must be compatible with the Cisco IOS software release level, as shown in 
Table 1.
