Prerequisites for 1-Port ADSL WAN Interface Card
A 1-Port ADSL WIC must be installed in the router to match the DSL service to be configured.
Restrictions for 1-Port ADSL WAN Interface Card
•
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 available bit rate (ABR) class of service (CoS).
•
For the Cisco 2600 series routers, the ADSL WAN interface card should be inserted only into on-board WIC slots or 2W network modules. This card does not function properly in older network modules.
•
For the Cisco 3600 series routers, the ADSL WAN interface card should be inserted only into on-board WIC slots or 2W, 1FE2W, 2FE2W, or 1FE1R2W network modules. This card does 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 Cisco 2600 series and Cisco 3600 series.
•
VoATM AAL2 and AAL5 are supported only if voice and data use separate permanent virtual circuits (PVCs).
•
VoATM AAL2 supports digital voice (T1/E1) only, while VoATM AAL5 supports both analog and digital voice.
•
VoIP is not supported 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.

ADSL WAN Interface Card
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 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.

•
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 Cisco 2600 series and Cisco 3600 series platforms.
•
Supports 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.
How to Configure 1-Port ADSL WAN Interface Card
•
Configuring the ADSL Port on the ADSL WAN Interface Card (required)
•
Verifying ATM Configuration (optional)
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

Glossary
ABR—available bit rate.
ADSL—asymmetric digital subscriber line (ADSL) available through several telecommunications carriers to accommodate the need for increased bandwidth for Internet access and telecommuting applications.
ATM—Asynchronous Transfer Mode. International standard for cell relay in which multiple service types (such as voice, video, or data) are conveyed in fixed-length (53-byte) cells. Fixed-length cells allow cell processing to occur in hardware, thereby reducing transit delays. ATM is designed to take advantage of high-speed transmission media such as E3, SONET, and T3.
CLI—command line interface.
CO—central office, or local exchange (local switch), which terminates individual local telephone subscriber lines for switching, and connects to the public network. Known as a class 5 switch office. For example, 5ESS by Lucent and DMS 100 by Nortel.
CPE—customer premise equipment, including devices such as channel service units (CSUs)/data service units (DSUs), modems, and ISDN terminal adapters, required to provide an electromagnetic termination for wide-area network circuits before connecting to the router or access server. This equipment was historically provided by the telephone company, but is now typically provided by the customer in North American markets.
DSL—digital subscriber line available through several telecommunications carriers to accommodate the need for increased bandwidth for Internet access and telecommuting applications.
FXO—foreign exchange office. A FXO interface connects to a central office.
FXS—foreign exchange station: A FXS interface connects directly to a standard telephone, supplying ring voltage, dial tone, etc.
G.SHDSL—multirate symmetrical high-speed digital subscriber line.
PVC—permanent virtual circuit.
