loaded into a card, and it is typically bundled with the Cisco IOS
image. (In general, Cisco does not refer to modem code
microcode.)
DSP Digital Signal Processor (DSP). The processor that does the
modulating and demodulating. The modem modulation protocols,
such as V.34 and V.90, that run in the DSP.
1. Examples and text that refer to both MICA and Microcom modems use the term firmware (not portware).

Inspecting and upgrading modem firmware is a fundamental part of commissioning a NAS. Cisco posts
new firmware versions on CCO for you to download via FTP. For more information, go to the
Cisco Software Center at the following URL:

A specific architecture surrounds integrated modem technology. Integrated modems get their modem
firmware from a file that is stored in one of three places:
" Bundled into the Cisco IOS software
" Stored in Flash memory
" Stored in bootFlash memory
The modem looks first for its firmware inside the bundled Cisco IOS image. The modem will not look
outside the bundled image unless you manually change the configuration settings by using
the copy source modem command or spe command.

Before you upgrade modem firmware for MICA or Microcom modems, you should perform
the following tasks:
" Determine the version of firmware that is currently loaded in each modem
(for example, 2.6.2.0).

" Find the version of firmware that is bundled with the Cisco IOS. The show modem map command
displays the region of NVRAM that identifies where the modems get their firmware from at bootup.
The field  IOS-Default indicates that the modem gets its firmware from the bundled IOS image.
At the end of the display, you see the versions of firmware that the Cisco IOS found and where they
are stored. Bundled firmware is stored in the directory system:/ucode.
The following example shows that MICA portware 2.6.2.0 is mapped to the modems and bundled
with the Cisco IOS software:
