Upgrading Modem Code

Modem code is a generic term applied to a modem code file, which is also called modem code for
MICA modems and firmware for Microcom modems.
With new systems, Cisco loads a Cisco IOS software-compatible version of modem code and copies
the version to the installed modem modules. A map of the version(s) of modem code copied to the
modem RAM for each modem module is stored in nonvolatile random-access memory (NVRAM)
so that it is retained over power cycles.
Note You do not have to take any action to use the pre-installed version of modem code with new
systems.
You can acquire new modem code in several ways:

memory and mapped to the modems. If you choose to use the modem code bundled with your installed
Cisco IOS software, you could be reverting to a previous version of modem code. Also note that once you
map the bundled modem code (using the copy system:/ucode/filename modem command or, for Cisco IOS
releases earlier than 11.3A or 12.0, the copy ios-bundled modem command) to your modems, each time you
upgrade the Cisco IOS software, the new bundled modem code is automatically mapped to your modems. See
"Displaying Modem Code Versions," later in this appendix, for details on displaying modem code versions
mapped to modems, installed in system Flash memory, and bundled with the Cisco IOS software on your
access server.

How to Obtain Modem Code

You can obtain modem code in one of two ways:
•
•
Cisco periodically releases new modem code versions (with bug fixes or new modem features)
that improve your system's overall modem performance.
Cisco also might ship modem code on diskette with spare boards or offer modem code for
purchase with spare boards.
Modem code is also available on the Cisco Software Center.
Understanding the modem code scenarios possible for your access server.
Choosing an upgrade strategy.
Finding out the modem code version installed on your access server.
Upgrading the modem code.
Cisco ships the access server with the latest version of modem code installed in the system Flash
Bundled in regular Cisco IOS releases. See "Using the Modem Code Bundled with Cisco IOS
Software" for details.
Unbundled from Cisco Connection Online (CCO) or supplied on diskette. This can be either a
more up-to-date version of modem code released before the next Cisco IOS release (when the
modem code will be bundled with the Cisco IOS release), or a special version of modem code
shipped with a new board. See "Upgrading Modem Code from the Cisco CCO TFTP Server" and
"Upgrading Modem Code from Diskettes" for details.
