The ADSL feature is supported in the IP/ADSL Image ("y7" image) for the Cisco 1700 Series. Cisco 2600/3600/3700 series routers require a PLUS IOS image for ADSL if using 12.2T. From 12.3 Mainline and beyond ADSL WIC support is available in the "IP Base" feature set. Some QoS features require an advanced image (IP PLUS, IP VOICE, or above) for Cisco 1700/2600/3600/3700 series router support.

The ADSL over POTS WIC (WIC-1ADSL), is available on the Cisco IOS 12.2(13)T Release for the Cisco 1700/2600/3600/3700 series routers.
