Introduction

The Cisco 1700, 2600, and 3600 Series Routers support the Asymmetric Digital Subscriber Line (ADSL) WAN Interface Card (WIC). All three platforms are configured essentially the same, but there are differences in hardware and in the Cisco IOS® Software release required for each one. Throughout this document, the Cisco 1700/2600/3600 will be called the Cisco ADSL WIC.

This document provides a sample configuration that shows a Cisco ADSL WIC that has been configured with AAL5SNAP and routes IP to a Cisco 6400 Universal Access Concentrator (UAC).

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on these software and hardware versions:

• Cisco 6400 UAC-NRP IOS Software Release 12.1(3)DC1

• Cisco 6400 UAC-NSP IOS Software Release 12.1(3)DB

• Cisco 6130 DSLAM-NI2 IOS Software Release 12.1(5)DA

Hardware Requirements

In order to support the ADSL WIC on the Cisco 2600/3600, this hardware is required:

For the 2600:

• Chassis WIC slots

• NM-2W

For the 3600:

• NM-1FE1R2W

• NM-1FE2W

• NM-2FE2W

• NM-2W

Note: For the Cisco 3600, these do not support the ADSL WIC:

• NM-1E1R2W

• NM-1E2W

• NM-2E2W

Software Requirements

In order to support the ADSL WIC, these minimum Cisco IOS Software releases are required:

• Cisco IOS Software Release 12.1(5)YB (Plus versions only) on the Cisco 2600/3600.

• Cisco IOS Software Release IOS 12.1(3)XJ or later (Plus versions or ADSL feature set only) on the Cisco 1700. The ADSL feature set is identified by "y7" in the image name; for example, c1700-sy7-mz.121-3.XJ.bin.

  When you download the image for the Cisco 1700, make sure you select the image name of 1700. Do not download a 1720 or a 1750 image. The features will not support the ADSL WIC.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
