1-Port ADSL WAN Interface Card
This feature module describes the 1-port Asymmetric Digital Subscriber Line Wide Area Network (ADSL WAN) Interface Card feature for Cisco 1700 series, Cisco 2600 series and Cisco 3600 series routers. It describes the benefits of the new feature, supported platforms, configuration, related documents, and provides command reference information.
This document includes the following sections:

Configuring the ADSL WAN Interface Card
Feature Overview
The ADSL WAN interface card is a 1-port WAN interface card (WIC) for the Cisco 1700 series, 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 2600/3600 series platforms, and AAL5 only for the 1700, for both voice and data service.
The general topology is shown in Figure 1.
Figure 1 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.
Benefits
•
Enables business class broadband service with voice integration, scalable performance, flexibility, and security.
•
Aggregates both ADSL and other transport options into a single box.
•
Provides both POTS and ADSL high-speed digital data transmissions between the customer premise equipment (CPE) and the central office (CO).
•
Supports ITU G.992.1 (or G.DMT, which specifies full-rate ADSL).
•
Supports and complies with ANSI T1.413 issue 2, and ITU G.992.1 (G.DMT for full-rate ADSL).
•
Supports ATM AAL2 and AAL5 services on the 2600/3600 series platforms and AAL5 services on the 1700 series platform and applications (including VoATM voice), ATM class of service (variable bit rate-nonreal time [VBR-NRT], variable bit rate-real time [VBR-rt], and unspecified bit rate [UBR]) and up to 23 virtual circuits on a WIC.
•
Provides ATM traffic management to enable service providers to manage their core ATM network infrastructures.
Restrictions
•
The ADSL WAN interface card does not support dual latency. When the ADSL link is intended to support both voice and data traffic simultaneously, the link should be configured for either all fast-path data or all interleave data with an interleave depth of zero to insure that latency is minimized. In addition, the total supported data rate must be reduced to adjust for the reduced coding gain, which is usually present with high-latency traffic.
•
The ADSL WAN interface card does not support ABR class of service (CoS).
•
For the Cisco 2600 series routers, the ADSL WAN interface card should only be inserted into on-board WIC slots or 2W network modules. This card will not function properly in older network modules.
•
For the Cisco 3600 series routers, the ADSL WAN interface card should only be inserted into on-board WIC slots or 2W, 1FE2W, 2FE2W, or 1FE1R2W network modules. This card will not function properly in older network modules.
•
When using AAL2, analog voice is not supported. Voice calls should come through a digital voice card, such as the NM-HDV.
•
VoATM is supported in both AAL2 and AAL5 modes on the 2600 and 3600 series. VoATM AAL5 is supported on the 1700 series.
•
VoATM AAL2 and AAL5 are only supported if voice and data use separate PVCs.
•
VoATM AAL2 supports digital voice only (T1/E1), while VoATM AAL5 supports both analog and digital voice.
•
VoIP is not supported until a later release unless the ADSL WIC carries only voice traffic (with no data). The QoS features necessary for VoIP and data sharing the same PVC, or different PVCs on the same interface, are not supported yet. These features include LLQ, LFI and tx-ring tuning.

Configuring the ADSL WAN Interface Card
This section contains the following information:
•
Configuring the ADSL port on the ADSL WAN Interface Card
Features used on the ADSL WAN interface card must also be configured on the DSLAM. See the documentation for the specific DSLAM for information about configuring features.
Configuring the ADSL port on the ADSL WAN Interface Card
To configure an ADSL port on the ADSL WAN interface card, complete the following steps:
Verifying ATM Configuration
Use the following commands to verify configuration:
•
Use show running-config to verify current configuration and to view the status for all controllers.
•
Use show controllers atm slot/port to view ATM controller statistics.
•
Use show atm vc to verify the PVC status. Make sure that active PVCs are up.
•
Use debug atm events to help identify ATM related events as they are generated. Use debug atm errors to indicate what interfaces are having trouble.
•
Use show ip route to identify an entry for the ATM interface you configured and to show that an entry for the ATM slot/port you configured it.
•
Use show atm map to display the configured list of ATM static maps to remote hosts on an ATM network.
•
Use show interface atm slot/port to view the status of ATM interface. Make sure ATM slot/port and line protocol is up, as shown in the following example:
