Modem Management Operations
In this Section
This section describes how to manage the modems on a Cisco AS5300 and AS5800 by using
the Cisco IOS.
The following sections are provided:

Task 1. Managing Modem Firmware

Task 2. Configuring Modems Using Modem Autoconfigure

Task 3. Gathering and Viewing Call Statistics
In this case study, Maui Onions and THEnet perform these same tasks to manage modem operations of
their network access servers (NAS). Maui Onions uses a Cisco AS5300; THEnet uses a Cisco AS5800.
For information on how to verify modem performance, see the section “Verifying Modem
Performance.”
Table 6-1 provides a list of terms for this section.

Term Description
MICA module MICA modem card containing 6 (HMM) or 12 (DMM) modems.
Portware MICA modem code.

SPE Service Processing Element (SPE). A SPE unit is defined as the
smallest software downloadable unit.
For Microcom, an SPE is an individual modem. For MICA, a SPE
is either 6 or 12 modems, depending on whether the MICA module
is single or double density.
ucode Short for microcode. Microcode in a Cisco NAS is code that gets
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
