Modem Code Scenarios
Table A-3 provides scenarios that can occur when you upgrade Cisco IOS software or modem code.
Table A-3
Modem Code Scenarios—Cisco IOS Software or Modem Code Upgrades
No.
Scenario
1
You receive a new access server from the Cisco factory.
2
You update Cisco IOS software, and you decide to use the
version of modem code selected by Cisco IOS software.
3
You update Cisco IOS software, and you decide not to use the
modem code selected by Cisco IOS software.
4
The modems are running a version of modem code from system
Flash memory that is different than the version bundled with
Cisco IOS software. You decide to revert to the bundled version.
5
Cisco releases new modem code, which is a later version than the
version currently running on the modems. You decide to use
Cisco's newest modem code.
1. To find out the version of modem in your system, use the show modem mapping command. This command displays the versions bundled with Cisco IOS
software (copied into Flash memory) and running on the modems.
2. In part, Cisco IOS software bases this decision on the last copy command issued. For more details about mapping, see Table A-5.
3. Cisco might ship this modem code on a diskette packed with the spare carrier card.

Update Process
• No action needed. The factory loads and maps a compatible
1
version of modem code.
• Update Cisco IOS software.
• No further action needed—Cisco IOS software automatically
downloads either its bundled version or a mapped version from
2
system Flash memory.
• Update Cisco IOS software.
• Copy the desired version of modem code file to system Flash
memory, then copy that file to the integrated modems on the
6-port module. See "Copy the Modem Code from Your PC to the
Modems," later in this appendix, for details.
• Use the Cisco IOS command copy system:/ucode/filename
modem. (or, for Cisco IOS releases earlier than 11.3AA or 12.0,
the copy ios-bundled modem command). Note that once you
map the bundled modem code to your modems, each time you
upgrade the Cisco IOS software, the new bundled modem code is
automatically mapped to your modems. See "Using the Modem
Code Bundled with Cisco IOS Software," later in this appendix,
for details.
• Copy the desired version of modem code file to system Flash
memory, then copy that file to the integrated modems. See "Copy
the Modem Code File from Local TFTP Server to Modems," later
in this appendix, for details.
