Checking the Interface Configuration

After configuring the new interface, you can perform the following tests to verify that the new interface
is operating correctly:
•
•
•
•
•
•
If an interface is down and you configured it as up, or if the displays indicate that the hardware is not
functioning properly, make sure that the new interface is properly connected and configured.

Configuring 1-Port ADSL WAN Interface Card

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

Configuring RF loopback
Display the router hardware configuration with the show version command. Check that the list
includes the new interface.
Display all network modules and their interfaces with the show controllers command.
Specify an interface with the show interfaces [type slot/port] command and verify that the first line
of the display shows the interface with the correct slot and port number, and that the interface and
line protocol are in the correct state, up or down.
Display the protocols configured for the entire router and for individual interfaces with the show
protocols command. If necessary, return to configuration mode to add or remove protocol routing
on the router or its interfaces.
Display the running configuration with the show running-config command, and the configuration
stored in NVRAM using the show startup-config command.
Use the ping command to send an echo request to a specified IP address. Each returned signal is
displayed as an exclamation point (!) on the console; each signal that is not returned before the
timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good
connection; a series of periods (.....) or the message "timed out" or "failed" indicate that the
connection failed.
