What is Modem Software?
Modem software is a generic term referring to the code that a modem requires to operate. Specific instances of modem software include MICA Portware and Microcom firmware.

Which Modem Software Should I Use?
MICA Portware is designed specifically for use with access servers with MICA 6-port modem modules installed. Platforms which support MICA modems include the 3600, 5200 and 5300.

Microcom firmware is designed specifically for use with access servers with Microcom 12-port modem modules installed. Microcom modems are only supported in AS5200 channel configurations.

Why Should You Upgrade Modem Software?
Cisco periodically releases new modem software versions with bug fixes and/or new features.  Upgrading your modem's software should result in improved system performance and reliability.

Cisco is pleased to announce the availability of the latest version of MICA Portware and Microcom firmware.  Portware 2.5.1.0 enables V.90 56K connections while continuing to support K56flex 1.1 connections.  2.5.1.0 also introduces Cisco Dial-out and Fax-out capabilities to the MICA modem platform.  Firmware 5.0.40 introduces support for the ITU-T V.90 modulation to the Microcom modem platform.

Choose a Modem Code Upgrade Strategy
Use the [Understanding Modem firmware on Cisco 3600 Series] and the [Understanding Modem firmware on Cisco AS5200 & AS5300 series] documents to learn about choosing a modem code upgrade strategy for your Cisco Access Servers.

How to upgrade Your Access Servers' Modem Software Downloading Modem Code should be a 4-step Process:

1. Use your web browser to download Router Software Loader 7.0 from CCO to your Win95 PC.
2. Install Router Software Loader 7.0 on your PC.
3. Download new modem software image from CCO to your PC by using your web browser.
4. Use RSL 7.0 to install the new modem software from your PC to your access server

Cisco Router Software Loader (RSL)
Router Software Loader (RSL) is used for loading Cisco Software onto the following supported platforms (currently Cisco 7200, AS5300, AS5200, 4x00, 3600, 2600, 2500, 1600 and 1000). Please note that RSL is only supported on Windows 95 platforms.

Note: It is possible to download the modem software to your Access Server via methods other than RSL. This includes using the TFTP or RCP protocols. For information on how to do this, please read on [Upgrading Modem Code Using TFTP].

Warning: Using TFTP or RCP to download modem software requires a working TFTP or RCP server. Cisco does not support TFTP or RCP servers, however, Cisco does provide a free TFTP server for Windows95 as a courtesy.
