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 is referred to as the Cisco ADSL WIC.
This document shows a Cisco ADSL WIC connected to a Cisco 6130 DSL access multiplexer (DSLAM) and terminates on a Cisco 6400 Universal Access Concentrator (UAC). The Cisco ADSL WIC is configured as a Dynamic Host Configuration Protocol (DHCP) server with PPP over ATM (PPPoA).
The Internet Service Provider (ISP) gives the subscriber a range of IP addresses, 10.0.0.1 to 10.255.255.254, with a mask of 255.0.0.0. The IP address 10.0.0.1 is manually configured on the Ethernet interface of the Cisco ADSL WIC. The left over IP addresses is assigned to a DHCP pool and leased to the local LAN devices attached to the Ethernet network of the Cisco ADSL WIC.
Before attempting this configuration, ensure that you meet these requirements:
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
The information in this document is based on these software and hardware versions:
To support the ADSL WIC on the Cisco 2600/3600, these hardware products are required:
2600: Chassis WIC slots, NM-2W
3600: NM-1FE1R2W, NM-1FE2W, NM-2FE2W, NM-2W
Note: For the Cisco 3600, ADSL is not supported on WIC NM-1E1R2W, NM-1E2W, or NM-2E2W.
To support the ADSL WIC, these are the minimum Cisco IOS Software releases 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.
Note: 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 does not support the ADSL WIC.
