1-Port ADSL WAN Interface Card for Cisco 2600 Series and Cisco 3600 Series Routers

The ADSL WAN interface card is a 1-port WAN interface card (WIC) for the Cisco 2600 series and Cisco 3600 series routers. The card provides asymmetric digital subscriber line (ADSL) high-speed digital data transfer between a single customer premises equipment (CPE) subscriber and the central office.

The ADSL WIC is compatible with the Alcatel Digital Subscriber Loop Access Multiplexer (DSLAM) and the Cisco 6130, Cisco 6160, and Cisco 6260 DSLAMs with Flexi-line cards. It supports Asynchronous Transfer Mode (ATM) Adaptation Layer 2 (AAL2) and AAL5 for the Cisco 2600 series and Cisco 3600 series platforms for both voice and data service.

The general topology is shown in the figure below.

General Topology for ADSL WIC

Note	ADSL is a last-mile access technology, which has an asymmetrical data rate running over a single copper wire pair.

Use the following commands to verify configuration:

• To verify current configuration and to view the status for all controllers, use the show running-config command.
• To view ATM controller statistics, use the show controllers atm slot/port command.
• To verify the PVC status, use the show atm vc command. Make sure that active PVCs are up.
• To help identify ATM related events as they are generated, use the debug atm events command.
• To indicate what interfaces are having trouble, use the debug atm errors command.
• To identify an entry for the ATM interface you configured and to show an entry for the ATM slot/port you configured, use the show ip route command.
• To display the configured list of ATM static maps to remote hosts on an ATM network, use the show atm map command.
• To view the status of ATM interface, use the show interface atm slot/port command. Make sure that ATM slot/port and line protocol is up, as shown in the following example:
